What to do with the cloth sofa cover stained with crystal mud?

Whether it can be cleaned or not depends on the texture of the sofa and the degree of staining. First of all, you need to take off the sofa cover, put it in water above 50 degrees and soak it thoroughly, and then use it with Yinli.

Scrub with laundry detergent and dish soap with a lot of sub-surfactants.

Method 2: If the above method cannot remove the crystal mud, you can dissolve a little potassium permanganate in water, soak the dirty area in the solution for 10 to 20 minutes, and do not bleach. When taking it out, the sofa cover may be dark red, put the sofa cover soaked in potassium permanganate into the acetic acid solution, it will slowly change from dark red to the original color, and then dissolve a little acetic acid in water, and soak the dyed place in warm water for more than half an hour, and use fading to reduce the color difference of the dyeing. If it still doesn't clean, it's best to rinse it several times, and the stained area will also fade away without damaging the original color of the clothes.
