Is there a way to give someone a toilet swirly without risking infection?
If you give someone a swirly, you risk exposing them to harmful bacteria from the toilet water. Is there any way to clean a toilet super thoroughly beforehand to make it safe?
If not, if someone hypothetically installed a toilet in their basement that no one used for its intended purpose, would that be safe to use for swirlies? Particularly if you let it feed from an isolated water tank instead of the house plumbing and drain into another tank.
Flush the toilet, and then clean it with bleach. For added protection, have the swirlee wear goggles, maybe earplugs and a nose plug, and have them close their mouth.
If you’ve watched Jackass, Steve-O volunteered to sit inside a porta-potty as it was hurled into the air. If you don’t mind seeing shit fly everywhere, you can look at the PPE he was wearing. Your swirly will be like that stunt, but much cleaner.
If you just clean it thoroughly with normal bleach it should be clean enough. Many pathogens in general don't like to "stick" too well to non-porous surfaces. You can disinfect a toilet easier than you can a carpet. It's just that usually you aren't shitting on your own carpeting lol!
Bleach is literally going to kill everything in there. The bottle says 99.99% of bacteria and viruses only for legal reasons. Really it kills 100% when used properly.
Just bleach it twice, use a brand new scrubbing brush, hit the outside of the bowl and every little crevice you can see and you’ll be good to go.
If the toilet isn't used, the water should be pretty clean, should just be using normal house water. You probably wouldn't want it to sit for too long, and it should be cleaned occasionally with something that will kill bacteria. If it's used infrequently, I'd turn the toilet off at the wall, then flush the toilet a few times to bleed out any standing water.
Also, if it's a kink thing, be sure to have some sort of safe gesture or dead man's switch or something. Or a snorkel, lol.
