How to clean drink stains
Drink Stains (other than milk based)
Beer, white wine and most soft drinks usually rinse out during washing, but avoid bar soap or washing powder, as they are alkaline pH based whereas this soiling is Acid pH, so they may set the stains.
Milk (Soiling) is a protein and contains some fats. General washing powder will remove most recent milk stains in the wash because they contain alkaline salts which destroy protein. An alkaline product containg amonia will remove more difficult soiling. Older milk stains may be difficult to remove and the fats may not wash out, so drycleaning is the best option as the process dissolves the fat while removing the protein from pre-treatment.
Alcohol (soiling) can cause damage to the garment fabric dye. It may appear as a stain, but after laundering or drycleaning the adverse effects become apparent. Beer and white wine usually rinse out during washing, but avoid bar soap or washing powder, as they are often alkaline pH based whereas this soiling is Acid pH, so they may set the stains. Liquid detergent or a wool wash product is best.
