The best stain remover depends on the type of stain and the type of material you use. The safest stain remover is water, but if you have a protein stain hot water will make the stain worse.

Bonds need to be broken for the stain causing material, to dissolve in the water. hot water has additional energy which it transfers into the bonds, therefore loosening the stain more rapidly.
