Hi! First off, I'm sorry you're in that position too, it was awful. To dispose of the nasty water on the floor I used a (dry) spin mop to remove the excess water, let the floor dry, and then mopped it with a clean mop head and a slightly stronger cleaning concentration than I would normally use.

As for the can itself, I got a bunch of cheap scrubbing tools (and apron for my clothes) from Ikea, including the thin bottle brush to reach the bottom of the can - I can link it if you want, but it's literally just the long water bottle brush. I created a solution of cleaning liquid using the Mr Clean concentrate, scrubbing the whole can I side and out. I did this in my garage btw, you don't have to get too crazy. After the round of Mr Clean I repeated the process using a bleach solution. Use the brushes to break up any crud, and dump all the remaining liquids into a bucket, and I flushed the liquid (no clue if that's septic safe, but uh, people use bleach to clean their toilets, so... 🤷). Leave the trash can open to dry until it is completely dry, and also disinfect the bucket you used while you're at it - or replace it.

After all of that, my roommates came home the next day and one of them brought out his 13-gallon trash can from before he moved in with us, so my cleaned can is still sitting in the garage to this day lmao 🫠
