HELP!!!! White stuff on bottom of door trim

[DwDrummer]

I decided to wash my Denali this afternoon since I haven't had time to clean it good in several months. There's some white stuff on the very bottom of my door trim and I can not get it off. I've tried wiping it with a damp microfiber cloth, clay bar, swirl remover on a microfiber with no luck. I'd like to get it off tonight since my truck is nice and clean besides the nasty white stuff lol! If anybody can help me out I would greatly appreciate it! I will be up for several hours tonight so post away!

 

Thanks,

DW

I can't tell from the picture but I would first try some all purpose cleaner and then maybe strip wash.

I'm out of all purpose cleaner...anything else I can try that I may have laying around the house? I tried some mean green today and it didn't help.

That almost looks like glue from the double sided 3M tape holding the moulding to the door.  Hard to tell from the picture though.

Its harder water that accumulates in the gap between the trim and panel and eventually runs down to the bottom and down the paint. By the time is starts to run down the paint at the bottom, it dries up and the minerals leave behind the residue you see in the picture.

 

I had rubber door trim like this on my 2011 Chevy Colorado, it did the exact same thing. I removed the rubber trim and it gave the doors a much cleaner and smooth look.

 

Picture without the molding:

Looks like some calcium build up, use some full strength white vinegar, spray it on with a spray bottle and let it soak you can rub it with a soft bristle tooth brush. I remember answering this same scenario before, maybe it's just my imagination.

Will give the white vinegar a try today! Thanks!

[DwDrummer]

Vinegar didn't seem to help:(

Clay and Polish.

Revive might do the trick if you can get it in that area.

Bump a old thread! The spots are still there. I tried vinegar and CRL diluted to not budging it at all. Anybody else have any ideas? Thanks!

Have you tried toothpaste and a soft toothbrush?  I've seen that work wonders on stubborn car stuff.

Did you try Clay bar? I get some of that around my moulding as well. I just break out an older clay bar and Detail Spray and its gone.

Ended up getting 99% of it off with some water spot remover. I had scrub extremely hard and come back and buff those areas back out of my swirl killer. Thanks!:D

Where do you live Derek?  Snow belt? I get the same crap from the chemicals they use around here. My running boards were awful and had to use polish to get them back to new.
