I think the only real option for this is a clear plastic sheet that's had a chemical resistant thin film applied to the faces. One commercially available example is Makrolon AR2, it's polycarbonate with some proprietary coating that's listed as having >24hrs resistance to acetone and a few other chemicals.

According to several application guides/compatibility charts for ABS plastic (like this one), ABS is fairly resistant to the conditions present in a dishwasher (mild to strong alkaline, salts, no organic solvents, mild temperatures).
Please note that while the ABS structural backbone may be attacked by nucleophilic agents at the nitrile carbon, and that the ...

ABS isn't food safe so you may introduce toxic particles to your dishwasher and anything else in it. The combination of high temperatures and harsh chemicals could still degrade unprotected ABS despite temperatures being below glass transition. Other people have done it before and haven't had issues though, but I prefer to err on the side of caution.

According to Palstics International's Chemical Resistance Chart, the A-rated plastics (no solvent attack) towards acetone are:
ECTFE (Halar®): transparent films available
Fluorosint® PTFE: white
HDPE: transparent films available
Nylon®, Type 6/6: white
PP: clear sheets available
PPS: opaque white
PTFE: white
Among these, polypropylene appears to be the ...

Tritan is a co-polyester. It is prone to stress cracking in the presence of a number of common solvents - cyclohexanone and tetrahydrofuran are used as surface bonding agents.
Acetone can induce stress cracking, as can IPA.
I would suggest overprinting if you want to disguise the logo.
As for the aluminium item - take your choice - cyclo, THF, acetone, ...

I would suggest acetone for both - it's usually very effective for removing colours or inks of all kinds and I used to use it at work (in a lab - make sure you handle and dispose of it safely) to remove permanent marker.
