This is not cozy!
We have been camping for 38 years in trailers and our motorhome. We have used just about every product on the market for the toilet - blue, green, liquid, powder, pods - and are not really happy with any of them. (As a side note: once we were at a drain, dumped a bunch of Oxyclean in the tank, used a hose with a strong steam to fill the thing until suds came out the vent. It was fun, but not a long term solution.)
We only use the toilet for liquids. No paper, no feces, except in a couple of emergencies. It still manages to get unpleasant.
I have been searching on the 'net and read that liquid bleach might be used in our situation in a 1 to 8 solution with water.
Has anyone tried this? I am tempted to use a stronger solution. Please don't recommend any commercial products. As I said, been there, tried that, didn't work well enough. Can anyone recommend another simple chemical to help? Ammonia instead of bleach? Lots of vinegar? Baking soda didn't work.
Thank you much, and Happy Camping!
