So every couple months I clean my resin contaminated alcohol using alum powder (link to a video about the process)

After cleaning it I let it sit in the settling containers until I need to clean my alcohol again. At which point I swap the alcohol that was cleaned into my main wash and cure station tub and then put the dirty alcohol into the other tub I use exclusively for cleaning the alcohol.

Edit: For those curious I can share an image of what the alcohol looks like after it’s had 24 hours to settle in the settling containers.
