Keep a few rolls of TP for guests. Mostly sits unused otherwise. Last time I bought rolls was last year.
I certainly haven't done biological analysis, but in practice I'm totally clean afterwards. Doing a basic visual and smell test, the towel is definitely clean. Far cleaner than had I used TP. We just throw the small towel in the clothes wash after use and keep a clean stack near the toilet.
Haven't bought toilet paper in many years, wouldn't go back.
I cant bring myself to get rid of tp especially for if guests come by, but imagine towels do a better job of drying than paper.
It is just a couple drops of water after you shake off. If you're wearing underwear, it isn't that big of a deal if a couple drops of water get on there. You probably sweat more than that into your clothes each day.
People make a big deal out of something that really isn't.
Not buying much tp any more of course, but it still serves a purpose.
