There is blood on the quilt cover. I have washed it with the washing machine, but there are still blood stains. Now I want to wash it again, but what if I can't clean it? Ask me.

If it is contaminated for a long time, rinse it with clean water, and it will solidify when heated. Then wash with 10- 15% oxalic acid solution, because the blood contains protein, after a while. If it is still not clean, you can clean it with sulfur soap. When it is just polluted, wipe the polluted place with 10% tartaric acid solution.

2. 10% ammonia or 3% hydrogen peroxide can be used to wipe dirty places. White radish juice or carrot paste mixed with salt can remove blood from clothes.

5, the effect is very good. Remove blood stains with enzyme washing powder
