Pour the grated soap into a large bowl, pour a glass of hot water over it, and let it sit for 10-15 minutes to soften and dissolve. Then add 3 tablespoons of ammonia (salicylic acid) and 2 liters of hot water.
Mix the prepared solution thoroughly and soak the white laundry that needs refreshing in it. Leave it in the solution for 2-3 hours.
After this time, even the most stubborn stains, yellowing, or graying will disappear without a trace. The fabric will regain its freshness, and your clothes will look like new – sparkling clean and perfectly white.
