Read the comment with instructions man. Wipe with toilet paper first, as normal. Then wash with soap and water. Then dry with a towel. If you’re smearing poop all over everything you’ve got other issues to work out.
To answer your question, it is cleaner than just using toilet paper because you are wash with soap and water after you use the toilet paper. If you manage to get poop all over the towel when you’re done washing, then TP alone was never going to suffice.
I’ve got a menthol minty butt soap. For the small price of washing myself I get a refreshing, lingering blast of arctic freshness on those hot ‘n humid downstairs jungle days. It may still get swampy, but for a few extra moments- it’s glorious.
