Caustic soda de-greasing is suitable for hoods, cooktops and other very heavily greased items or worktops.
Before you use it, you need to have to good gloves and goggles! This is important. This is because Pyrolysis is highly corrosive and can cause a lot of damage to your eyes and skin in case of a splash!
Take an appropriate amount of caustic soda and add water to dissolve it. As it is heavy oil pollution do not add too much water. Become a solution can be. Then use a brush and stick the solution to apply to the hood where it needs to be cleaned. After a few minutes, then use a rag to scrub it clean. Some parts can also be soaked in the kerosene solution and then cleaned clean.
The use of kerosene is dangerous, so it is generally not recommended for use in the home. It is better to use some heavy grease cleaner available in the market. Its main become is also generally a strong acid or alkali, but because of the addition of other auxiliary materials, its nature is more gentle, and will not splash, the use of less dangerous.
Expanded Information:
The main chemical components of living oil stains are: including saturated and unsaturated glycerol esters of higher fatty acids. The esters are hydrolyzed in an alkaline environment to produce stearic acid and alcohols. Both stearic acid and alcohols are easily dissolved in water, and the effect of stain removal is achieved.
The chemical name of caustic soda is sodium hydroxide, the chemical formula is NaOH, commonly known as caustic soda, caustic soda, caustic soda, for a strong corrosive alkali, generally in the form of flakes or lumps, easily soluble in water (exothermic when dissolved in water) and the formation of an alkaline solution, and there is another deliquescence,
Sodium hydroxide can be used as alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; insoluble in propanol, ether. Disproportionation reaction with chlorine, bromine, iodine and other halogens. Neutralize with acids to produce salt and water.
