My son wants to know the best way to clean and remove rust from an old license plate without removing existing paint. I suggested electrolysis. Any better suggestions ? Thanks, Dave

Bar Keepers friend I use on rust. Just take it slow and try before rubbing to hard.

Thank you. Dave

Ive been having pretty good luck with Naval Jelly. I just kind of rediscovered it. Try it. Put it on thick and let it sit for about fifteen minutes. Then scrub it around with a tooth brush. Then rinse.Seal with Sani-wax or similar.

I used that stuff 35 years ago on cast iron bubble gum machine parts. I bought it from an ad in Hemmings Motor News. LOL Thanks Jim. Dave

Try this stuff from Home Depot, Dave. Not sold at Lowes.

Apply, gently agitate, rinse off after 5-10 minutes. Repeat as needed. Too many times or too long and it will remove the paint as well.
Good luck!

Dr.Dave
How much is that?

Thanks for the tip ! Great to hear from you. Dave

Finished product.."Rustoration". Painted tag and highlighted letters with sponge brush. Nothing serious. Dave

Long time no see, Dave! Hope you are well, my friend!
