If the stain is still there, spray it with carpet, then make it into powder and suck it off as usual.

In addition, the carpet will be cleaned once a year with a steam cleaning machine to suck away stains while spraying hot steam.

The ingenious use of organizational function

The kitchen is surrounded by oil smoke every day, which is the top priority of household cleaning.

Where there is a lot of oil, spray kitchen cleaner first, and then spread a napkin to keep the cleaner moist, fully combine with the dirt and not evaporate quickly.

After about 15 minutes, most of the oil stains will adhere to the wet tissue, so just pick up the wet tissue and wipe the oil stains clean.

Tips for bathroom cleaning

Because the bathroom is a place that must be used every day, if you are not careful, bacteria can easily breed and endanger the health of your family in a high temperature and high humidity environment.

If there are windows in the bathroom, it is best to open the windows from time to time to let the air circulate. In addition, the concept of dry-wet separation should be further popularized.

When cleaning the bathroom, what should I do to relax? The following cleaning tips:

1.

Toilet:

Because the toilet is easy to be contaminated with urine stains, feces and other dirt, if it is not cleaned on weekdays, it is easy to form macular stains, and it will also breed mold and bacteria.

The correct step of cleaning is to lift the seat cushion first and spray it with toilet cleaner. After a few minutes, brush it thoroughly with the toilet brush, and then brush the gaps such as the toilet seat.

Because the water outlet at the inner edge of the toilet is a place where it is easy to hide dirt and shelter evil people, the general spray toilet cleaner can't spray the cleaner there smoothly. Therefore, it is best to use the toilet cleaner with unique duckbill head design to go deep into the inner edge of the toilet to remove stubborn dirt.

As for the pedestal on the outside of the toilet that is easily overlooked by ordinary people, it should also be sprayed with detergent, washed with water and oil, and finally dried with a clean cloth to make it as bright as new.

Finally, put a "wash-free automatic toilet cleaner" in the toilet tank to do a good job of cleaning and descaling on weekdays.

However, people are reminded not to mix acidic, neutral or alkaline cleaners with different ingredients to avoid danger due to chemical changes.

2.

The bathtub pot is getting heavier and heavier, which will definitely affect the temperature of cooking in the future, so be sure to wash the front and back together, and then put it on the stove to dry it with fire to completely remove water.

4, rattan furniture with ordinary detergent brush.

Washing rattan furniture with ordinary detergent will damage rattan.

It is best to scrub with salt water, which can not only decontaminate, but also make the rattan soft and elastic.

The dust on the rattan chair can be brushed from the inside out with a soft brush.

If the stain is too heavy, you can wipe it off with detergent and then dry it.

If it is a white rattan chair, put a little vinegar at last and neutralize it with detergent to prevent discoloration.

Scrubbing rattan chairs with a brush dipped in baking soda water can also remove stubborn dirt.

5. Wipe the computer, TV and stereo with water.

Computers, televisions and stereos are all precision machines, so don't wipe them with water when cleaning.

When cleaning household appliances, you can wipe the dust with a portable electrostatic brush to prevent static electricity.

Small holes or button slots for inserting headphones in household appliances should be cleaned with cotton swabs.

If the dirt is hard, it can be cleaned with a toothpick cloth, which is easy to remove.

Diluted alcohol is best for keys on stereos and computers. You can spray alcohol on the keys with a watering can and then wipe them with a dry cotton cloth, which can not only remove stains, but also disinfect them.

At the same time, clothes softener can also come in handy when cleaning at home. Wipe household appliances with water mixed with softener, and it is not easy to get dust in a week, and the effect is excellent.

6. When cleaning, the walking route is messy.

The specific policy is: from top to bottom, from inside to outside, put the cleaning utensils in a bucket, let it follow you at any time and clean the room clockwise.

Store the required cleaning tools in a centralized way to keep the cleaned room clean and tidy.

The cleaned house is stained with dust again.

Market prospect analysis

With the rapid development of China's economy, the acceleration of urbanization and the emergence of more urban buildings, the problem of building pollution has become increasingly prominent, the most prominent being the exposed external walls and increasingly luxurious interior decoration. The external walls of buildings are naturally weathered by wind and sun all the year round, and all kinds of dust in the atmosphere are attached to the outside of buildings. The direct action of many corrosive substances also pollutes and destroys the appearance of buildings and loses its original charm. Greatly affected the beauty and image of the city. With the development of high-grade, complicated and humanized interior decoration, a large number of expensive decorative materials and supporting facilities are widely used, and at the same time, due to human and natural factors, they are easily polluted. Therefore, whether it is the external cleaning or the internal cleaning of buildings, the traditional cleaning methods can not be satisfied, and professional cleaning services are needed.

With the development of economy, the acceleration of urban construction and people's pursuit of high-quality life, professional cleaning service has attracted more and more attention and favor.

Patriotic health, city appearance activities, national health cities and excellent tourist cities also stimulate the rapid development of professional cleaning and cleaning market, making the property cleaning market present an exciting buyer's market. According to the statistics of the Ministry of Information Industry, there is a potential demand of 300 billion yuan of professional cleaning market in China every year.

Land reclamation and daily cleaning

Building decoration often leaves all kinds of rubbish and dirt, and a lot of stains or stains such as cement, paint, coating, glass glue, water pollution and rust will be left on the ground and walls. These must be handed over to the owner through professional reclamation projects. The quality of land reclamation project directly affects the quality and grade of daily cleaning work, so it is highly valued by the owners. The market capacity is huge.

Daily cleaning business can be divided into family cleaning and unit cleaning, that is, providing high-quality cleaning services for owners on a regular basis. At present, due to the increasing specialization and popularization of cleaning services, owners pay more and more attention to daily cleaning, which has great market potential.

High-altitude external wall cleaning

The dirt attached to the external wall of a building is generally firmly combined with the surface of the building, because the dirt with weak combination has been washed away by the wind and rain, leaving behind.

Dirt can be roughly divided into the following categories:

● Dust combined with coulomb force and wall surface;

● Solid dirt such as dust, scraps of paper and leaves attached to the wall by organic matter;

● Insect and bird fragments that hit the wall after high-speed flight and stick to the wall after death;

● Air pollution, causing rust spots on the exterior wall surface;

● Waterline left by rainwater containing organic matter and inorganic salts;

● Dirt carried by rainwater left on the roof.

Due to the different types, bonding force and bonding methods, as well as the different deposition time on the external wall, the above dirt is very different to clean, which puts forward a series of technical requirements for building external wall cleaning. Because of the danger and complexity of exterior wall cleaning of high-rise buildings,

So this job is a science major, with great technical difficulty and high profit.

At present, cities are increasingly aware that the cleanliness of buildings directly represents the face of the city. For this reason, Beijing, Shanghai, Guangzhou and other developed cities have issued a series of local laws and regulations, requiring building owners to clean the external walls regularly, especially before major festivals, celebrations and conferences, the external wall cleaning business can be described as in short supply.

Generally, the cleaning service of high-altitude external walls is charged by area, and the unit price is determined according to factors such as cleaning materials, cleaning agents, cleaning difficulty, cleaning area, cleaning height and cleaning requirements. At present, the market price is about 1.2-3.0 yuan/square meter in big cities, and it is relatively high in remote areas, generally around 3.0-6.0 yuan/square meter.

Renovation, crystallization and maintenance of stone natural stone is widely used in many high-grade buildings because of its natural beauty and outstanding decorative effect. However, because the stone itself contains minerals and pores such as iron and calcium in different degrees, a large number of pollutants such as dust, waste gas, acid rain and freezing are destroyed in the environment, improper mining, transportation, installation and bonding processes, poor maintenance during use and many other reasons, it is easy to appear whitening, rust spots and water stains. Oil stain and wax layer, cracks and frost damage, pulverization, fading and other diseases. In addition, in daily use, edible oil and engine oil, rust, ink, coffee, tea and other organic substances will also corrode stone, thus affecting the natural color and beauty of stone. Dyed stone will cause visual pollution to urban landscape and indoor environment, and also shorten the service life of stone.

In order to nip in the bud, prolong the life cycle of stone, keep the stone youthful and bright, and make the decorative effect of stone lasting and bright, the stone beauty maintenance industry came into being. The main services include stone waxing and polishing, stone crystal hardening, stone renovation, multifunctional maintenance, stone rust removal and glue removal, etc.

Stone beauty maintenance market has great potential. The annual consumption of decorative stone in Beijing reaches 22 million square meters, but the maintenance cost of stone is only one tenth of the average level of European countries. According to the statistics of Beijing stone conservation industry association, the total cost of stone conservation project in Beijing in 2005 was about 80 million yuan, and if calculated according to the European level, the annual investment in stone conservation in Beijing should be around 800 million yuan, and the national market potential is very huge.

Special purpose

It mainly includes floor waxing and polishing technology, furniture waxing and maintenance technology, stainless steel cleaning and maintenance technology, glass cleaning technology, combined chandelier cleaning technology, carpet cleaning and nursing technology, leather sofa cleaning and renovation technology, air conditioning cleaning technology, water dispenser cleaning technology, computer cleaning technology, range hood and oil fume duct cleaning technology. Special services are mainly carried out in land reclamation or daily cleaning services, or independently. The market potential is huge.

Painting service 1. Wall quality inspection.

This step should be completed in the closing stage. First of all, everyone should comprehensively check whether the walls that need to be painted in the room are solid and flat.

If there are big cracks and holes in the wall, the developer or property should be advised to redo it.

A single hole can be filled with gypsum.

2. Preparation before scraping putty.

Ensure that the wall is solid and flat, clean it with steel brush or other tools, and try to make the wall free of floating soil and subsidence.

Roll the concrete interface agent evenly on the wall as far as possible, and after it is dried (generally more than 2 hours), you can blow putty.

3. Scrape water-resistant putty.

Before blowing putty, measure the flatness of the wall with a measuring ruler of more than 2M to determine the method of blowing putty.

Generally, putty can be scraped on both sides of the wall, which can both level and cover the background color.

Putty with poor flatness needs to be scraped several times locally.

If the wall with poor flatness is seriously inclined, consider scraping gypsum for leveling first, and then scraping putty.

The interval between each batch scraping of putty should be more than 2 hours (after the surface is dry).

Step 4 polish putty.

After water-resistant putty 1-2 days, putty grinding will be started.

Polishing can be carried out at night, with a light bulb of 100 watt or more close to the wall for lighting, and check the flatness while polishing.

5. Brush the primer.

After the floating dust on the polished putty surface is cleaned, it can be primed.

Primer can be brushed once, and it must be uniform. After drying (2-4 hours), the next step can be carried out.

6. Brush the top coat.

Generally, the top coat is brushed twice, and the interval between each time should be more than 2-4 hours (depending on the surface drying time) until it is basically dry.

It takes 1-2 days for the paint to completely dry after the second coating. Before the paint is completely dry, pay attention to waterproof, drought-proof and sun protection to prevent problems with the paint film.

External wall construction: 1. New wall construction: the painted bottom layer of the external wall of the building needs sufficient curing period, and the surface of fresh water mortar concrete must be cured for a reasonable time to make it "spit alkali" and fully dry.

The bottom surface should be dry, solid and firm, and there should be no defects such as sand, cracks and looseness.

2. Construction method: It is not advisable to scrape putty on a large area for exterior wall painting, and the putty layer should not be too thick. The material is polymer cement putty.

Generally, primary coating and secondary surface coating are adopted.

According to the requirements of engineering quality, the number of surface painting can be increased appropriately.

The painting construction is generally carried out from top to bottom, and each painting should be maintained and renovated at the dividing line, the wall surface, the junction of yin and yang angles or the downpipe: the old wall renovation and the three newly painted walls.

3. For the old coating with no bearing capacity, looseness and peeling, it should be completely carved out at the root together with putty, and cleaned and dried before leveling with putty.

For the slightly powdered but firm old coating, it can be polished flat and then primed.

The old coating with serious pulverization should be thoroughly cleaned in advance, and the old oily wall should be completely removed.

The heavily polluted base should be clean.

For the wall eroded by mold and algae for a long time, remove it mechanically, or treat it with bleach solution, then rinse it with water, dry it and level it.

The current situation of cleaning industry in China started late. From the current situation and development of the industry,
