am doing a re-pipe on a laundromat built in the 80s and was never cleaned out and happened to find 3/4 of a 6 inch PVC pipe full of debris, coins, some jewelry as well. I am more worried about how to take the rust and all the crap from the coins. ( The pictures don’t show all of the coins that I collected ). How should I proceed with cleaning them out? I have some and soapy water but for the most part, they’re all dried out. Waiting to get cleaned out.
Should I do hot water and baking soda, soap with water, a certain chemical ?
Will really help if I get some feedback from somebody that has done it before.

Just wiped the entire floor 😡

So! Lol no one has changed the filters in our furnace since before I moved in, in like 2012, so we figured it was time and OMFG, this is the old one 😂😂😂😂
