I have 2 1/2 year old boy who takes off his training pants and hurls the "contents" on the walls. I try to clean up as much as I can, but if you don't get it within 5 minutes, it turns into cement, and is impossible to get off. I've tried scrubbing with a brush, with all kinds of soaps and detergents, even bleach. Nothing works. Is there any kind of heavy duty chemicals that can break this stuff down? Potty training. I'm at the end of my rope! He just doesn't seem to understand that it goes in the potty. I've tried everything I can think of. Treats, schedules, songs.... Nothing seems to work. This has been going on fore awhile now, and we need to get through this phase. ANY advice is appreciated, especially with the clean up.
