Wipe first. Use soap if you want to be really clean.

I got a cheap bidet a few years back and I use it all the time. The fancy ones can be nice but most of the extra features are gimmicky things that don’t have a large impact on function. They’re marketed like magic poop-away devices but bidets aren’t magic. Bidets are showerheads for your toilet bowl meant to make buttwashing more accessible. Use your bidet like a butt-shower instead of a magic no-effort poo cleaner and you’ll have better results.
