I have a 2009 550 clk cab. Not the entire dash, but the round section in the center with air vent controls, between the air vents, is sticky to the touch. Tried to clean with cleaner wipes and now there are surface scratches and it is still sticky.

The material seems different than any other part of the interior.

Any ideas?

Thanks.

This is a common problem with soft-touch coatings. You can remove the coating using a microfiber terry cloth and interior cleaner - just keep rubbing and it will come off, leaving smooth, plain plastic underneath (and it also will not affect the lighted ">>" markings as they are molded into the plastic).

I have replaced it with an original one for about 30$, it should be similar prices all around the world, if the cleaning does not work for you.

The part is held in place with a few clips.

I've use a microfiber cloth and gentle surface cleaner (I like Pledge multi-surface), but ti was too slow so I ended up using the microfiber cloth and fingernail polish remover and it worked like a charm.

I have the same problem on my CLK 550. Did the microfiber cloth/cleaner work?

Mike
Worked fine. Finally got around to it this weekend. At first it looks worse as all the surface gunk balls up. But once you get into it it cleans up real good.

Thanks to everyone for the advice.

This sounds like good advice but I was wondering if straight acetone from the paint store would be ok. Also, do you think that would work on the accessory pocket under the radio/Ac module?

Yes, fingernail polish remover is just acetone. And yes, it will work on the dash pocket, too.

Thanks, Rudeney, it worked fine but it left the plastic a bit dull and streaky. Any suggestions on restoring the appearance? Dave

Rodney,

Sorry not trying to be a know it all but....

Fingernail polish is ethyl acetate and acetone is dimethyl ketone. You can sort of smell the acetic acid (vinegary) odor in ethyl acetate.

Different properties and water solubilities.

Thanks,
Zill.

Hi Zill, it's been many years since I've been in chemistry class, so I'm just going by what's on the bottle. My wife's bottle of fingernail polish remover that she keeps in the cabinet along with all of her other manicure accouterments has a label with "acetone" listed as the first ingredient, then water, and then some other stuff. I think she has also had some "acetone free" remover, but she said that doesn't work as well on the newer "gel formula" polishes. Maybe the "acetone free" formula is the difference?

When I removed the "sticky" soft-touch material from my panel, I think I ended up using her fingernail polish remover. I remember I was doing this in the kitchen and not in the garage, so it makes sense that I'd use what was nearby.

Hey Rodney,

You're good.

I noticed that as well. The aroma of available nail polish remover has changed as well as the feel. More water based. Glad as hell I don't need that to remove toe nail polish. Buy your wife a man's solvent like lacquer thinner that sledge has it all working for it like:

alkyl esters: butyl or amyl acetate, ketones like acetone or methyl ethyl ketone, aromatic hydrocarbons like toluene, ethers such as glycol cellosolves, and/or alcohols.

Now that's a well rounded organic solvent!

Thanks,
Zill.

I know this is an old post, but has anyone tried the brand, "Goo Gone" for this issue? I think it is a more natural based solvent. I have used it on other adhesive issues in the past and it normally removes residue without damaging plastic, which does happen with stronger cleaners. Just wondering. Thank you!

I had the same problem. Tried Goo-Gone, 303, etc. Nothing worked. Finally used Armorall and some aggressive scrubbing with a microfibre cloth. Goey stuff finally started coming off. Now the round panel is smooth and like new.

Thank you BC300E! I used this Armorall cleaner + a microfibre cloth. I sprayed the solution on the cloth until damp and then gently rubbed the residue off. Took about 20 minutes.
