can anyone help? my husband has been a tilesetter for 9 years and all of the sudden he is allergic to tile grout. It has eaten up the skin on his hands and arms. Burning and itching. Wearing gloves helps but is there an ointment or salve or somethng that he can use to heal or relieve this condition? We have tried everything on the shelves at Walgreens and CVS. Even diaper rash iontment.
