Mike -
>>Be advised that for this color and brand (Ozark Trail) I have not found the ideal solvent to clean the residue.<<
Kev's recommendation of "nourishing" nail polish remover scrubbed with cut sections (not too small though) of generic magic eraser pad worked great on my red Ozark Trail tumblers. It has to be the "nourishing" type (fairly common in drug stores - I found mine at Wal-Mart). Red takes some extra work compared to other colors though. I use a "first pass" piece of magic eraser which will get a lot of gunk on it and then I finish with a second pad that is not gunked up. One thing I have learned is that the nourishing nail polish has a limited working time in regard to cleaning power (probably related to why it doesn't attack powder coating). At about 30 seconds you can tell it is starting to weaken a bit.
If I really have to scrub the powder coat for quite a while to clean a tumbler, sometimes there can be a very slight bit of gloss differential on the powder coating when inspected under bright light. Just wait until all parts of the tumbler are completely dry (and thus the powder coating is completely hard again) and just do a bit of buffing on the powder coating with a dry, clean magic eraser. It brings back an even gloss level.
Again, thanks to Kev for sharing this.
