In daily life, some stains of unknown origin often appear on clothes. After discovering them, they can't remember where they come from, so they often cannot prescribe the right medicine, so it is more effective to use a more general cleaning method.

【1】The stains on white clothes can be mixed with 4 parts of ammonia water at a concentration of 10%, 1 part of soda (sodium carbonate), 2 parts of high-quality white soap, 4 parts of alcohol and 100 parts of water. Dip the mixture with the cloth and wet the stain, wipe until the stain is removed, and then rinse it with clean water.

【2】The stain on any fabric can be mixed with 5 parts of ammonia, 3 parts of acetone and 20 parts of alcohol soap. You can also wipe it with a mixture of 1 part of alcohol, 1 part of ether, and 8 parts of pure turpentine oil at a concentration of 90%.
