> Better yet, buy and install a cheap bidet.

I rent and live in a flat, and I've also tried a bidet before. I would say that I've more success with the three shells.

Agreed, I'm more of the "you are fined 1 credit for a violation of the verbal morality statute" kinda guy when it comes to the toilet. The way you get stuff clean is by scrubbing, not squiring it with water and calling it a day and I'm sure as heck not squirting my under carriage and then using my fingers to scrub it outside of a shower.

You spray then use a piece of toilet paper to finish the business. Probably the same way you’d clean anything.

Can't clean my glasses with a bidet.
