I posted a reply on this subject last night and I guess it evaporated. When you apply the phenol carbolic acid don't get it on your skin, in your eyes, and don't inhale the vapors. Wear rubber gloves, goggles, and a mask. This is a safety message. Hate to see it erased.
Had to go at the sportin goods store. There was pee all over seat. Cleaned it with wad of TP. Applied TP for protection from nasty seat. Turned to sit down. The sensor flushed and the powerful vaccume force inhaled my TP. Not fun.
