Hello... I know that this is not a scientific question, but science could maybe help me here... Please tell me how could I decompose hair... Some human hair and hair from carpets (synthetic) stuck around the wheels of my boy's walker, so the wheels cannot spin. How could I decompose that hair, without damaging the plastic wheels. Are they any chemicals that I can find easily in a store, that could solve my problem? Thanks in advance!
