A friend was caring for her hospice mother overnights and I was back to work after GI surgery. We both started complaining about how ridiculous it was to try and get that "tar" off the toilet bowl (looks normal but sticks like cement!) and keep the bathroom bowl clean! I said somebody should invent "Tar-Gone" (good idea, eh?) for those stubborn deposits on the bowl. I discovered the Ty-d-bol! My toilet is easier to keep clean and not get fossilized remnants of 21 century diet. She doesn't want to pay for "fancy water"! Hey! Some people just like work for work's sake! Ty-d-bol doesn't CLEAN for you but it can help keep the gross stuff from sticking!
