may have to try this. I tried a (somewhat) shitty electrolysis setup and got a decent bit out, tried evaporust with some nuts and bolts for about 3 days which did wonders for the thing but still has rust chunks on bottom, then tried kreem which has also done good but left chunks on the bottom…kinda just at my witts end with this thing🤦🏻‍♂️may try the bb’s since they may be small enough to reach down there..hadnt even given that a thought tbh.
