Found the internal tinkerer in myself! I actually took apart a good part of the clothes washing machine. Intuition told me to leave the washing drum attachments in place. Also I left the concrete counterweight as-is. I took out the covers, and as much as I could get ripped to clean the washing detergent storage and dispensing well.
Fixing a otherwise resonant screw, whose looseness made the washing machine side lid corner keep a loud noise.
