There are many types of stains, and therefore, different methods for removing them. The goal of stain removal is to eliminate or reduce the impact of stains on the cleanliness of the fabric surface without affecting its properties. This necessitates the use of specific, targeted methods.

However, hotels and restaurants may not have all the raw materials, nor do they have the time to open a chemical raw material store. Generally, white stains are mostly removed with strong alkali and bleach. Colored fabrics are usually dark-colored and can be ignored. Other stains require different treatments.
