Tip 1:

1. When clothes are stained with ketchup, first scrape the ketchup stain from the outside in.

2, immediately rinse the back of the stain with a lot of cold water and rub gently, while continuing to use the force of the water flow through the stain.

3. Apply white vinegar to the back of the stain and rinse with water.

4. Repeat the above steps several times to remove the stain.

Trick 2:

1, if it is more stubborn dirt, you can first pour oxygenated bleach into the water, soak the clothes in it for 15 minutes, rinse with water and then wash.

2, if you still can't completely remove the stains with oxygenated bleach, under the premise that the clothing fibers can withstand it, soak in water with chlorine bleach for 15 minutes, then wash with water, and then wash in the usual way.
