Milk is sometimes claimed as a spot removal cleaner for such stains such as ink and blood. It doesn’t work, don’t bother trying to use milk to clean things. Milk can set in fabrics and become impossible to treat. It should never be used as a stain remover.
Soda water (fizzy water) is another old myth. Legend has it that the bubbles in soda water provide some properties capable of removing stains. The bubbles do not act as a stain remover at all, it’s no better than using water.
Alcohol can potentially provide some good stain removal properties but it can discolor fabrics. If you have looked at the underarms of some shirts you will see clearly when people are using alcohol based deodorant, the fabric turn white.
Lemon juice can potentially remove rust stains but the lemon juice will oxidize and may cause a stain that cannot be removed.
Ice has had a reputation as a remedy for chewing gum stains. The ice stiffens the gum and allows it to be picked from the fabric. This may work in limited cases, but gum dissolves easily in dry-cleaning solvent which is a much safer remedy than picking at the fibers of fabric.
Soap and water is the bedrock of home cleaning removal of all stains; however, dry based stains such as glue, paint, oil, and nail polish cannot be removed using soap and water. Please do not rub holes in fabrics in an effort to remove a stain. In some instances, soap and water can prevent the stain from being removed due to the alkali nature of the mixture which will oxidize stains such as coffee, tea, soft drinks, liquor, and fruit juice. Soap works by bonding fats and oils with water molecules, anything else it does is pretty much no better than just water.
Ironing a garment is a sure way to fuse, melt, and damage most synthetic fabrics. Wax dissolves in dry-cleaning solvent and can be readily and easily removed by any drycleaner.
Hair spray can remove ink stains; however, hair spray contains alcohol and other ingredients which can damage many dyes and fabrics.
Nail polish remover is used by many people to remove make-up and other stains; however, nail polish remover often contains acetone which can dissolve certain fabrics such as acetate.
Color-safe bleach does not exist. There is no such thing. Any bleach can remove color and damage dyes on fabrics.
