OH MY GOSH, just an hour ago, my husband, a plumber, of all things, went to dump the black tank into a bucket. The force was way harder and faster than he expected, and it splashed a lot onto the floor around the bucket. The stench is beyond unbelievable. Anyway, I used a trick I have used before - baking soda with vinegar. We covered the area. Let it sit, and now after he has mopped it up, it still stinks very badly. WHAT, if anything, have you done to alleviate the stench? He tried Simple Green, too. That didn't work at all. I think he is going to have to take the trailer out, power wash the floor, but there has to be something else...???Please help me help him. He is so bummed. BTW, I don't think this is the correct category, but I couldn't find one that was like what I wanted... I saw the word Blunders and that brought me here. I am looking to see if I can find a better place to post this to get some help.
