Best way to clean this. Thanks In advance guys
UPDATE: thanks everyone for all the great ideas. Some outside the box thinking I appreciate it.
Ultimately what I did was a citric acid soak followed by iso bath. Scrubbed with a glob mop. Got it like 99 percent clean but the etched dr dabber pattern at the bottom is still a little tan. I will be buying DCC for all future cleans but I’m very happy with the results I got from this. Shout out to all for the help!
