my group a grill has some flaky chrome on the top leading edge which annoyed me. i read online many solutions such as bleach which i tried with poor results. HLC or hydrocloric acid works great. took about 4 days of soaking, the plastic is unaffected and after words you rinse it off with water and its ready for proper paint. Much better than scuffing the flaky chrome hoping for the best!

Do you have a picture of the headlight trim - after HLC soak?

they will be out tomorrow i threw them in later, someone painted those black over the chrome with poor results, the acid removes both. hcl = maratic acid, available at Menards home depot ect
 
FWIW.......Muratic acid is the proper spelling.......
 
Haha could u use detergent 16, brick mortar cleaning acid..... worked well on the break dust on wheels I had once!! But ate through the carpet in my girls car ......hahaha!

I tried it and it put out a huge chemical cloud. I had to dilute it down to stop the fumes.

yeah it stinks, i wouldnt dilute it... that kind of defeats the purpose of the acid. i put my stuff in a sealed container right now im using a 5gallon bucket with a lid.
