Just 2 minutes ago I said I'd have this done within the hour. It was easier than I expected. I guess I'm modest. :P
This mod makes it so no trait is required to sponge bathe- anybody can do it. A neat sim who is a perfectionist and neurotic who is never nude and hydrophobic? Yep, they can sponge bathe. Anybody can.
Pretty cool for homeless sims or really poor sims, this was a good idea.
Don't use it with "Slobs can Sponge Bathe".
