Fix for sticky Porsche Carrera radio nobs

One of my customers cars came back from the Auto body shop with sticky radio nobs and every thing I used including alcohol didnt work and seemed to make them even more sticky.

Many things can cause this,using suntan lotion on hands is one.

I am not talking like there was something sticky on them but rather the material itself seemed to be degraded into a sticky very annoying mess.

Anyway after much research this is a problem for Porsche radio nobs and I found a you tube video that told how to prep with goof off and then spray paint them black.


I started to attempt to do this. Pulled the nobs off and decided to prep with 91% alcohol and low and behold the nobs were once again pristine just like a miracle!

I put them back on after leaving them in the sun to make sure they didnt revert back to "sticky". They were perfect!

I did not bother to paint them, no need.

I used alcohol before and it didnt work but most likely used 70 percent .

New nobs are 30 bucks a peice!

That was a good day.

I have had my share of "sticky" nightmare interior problems lately ,more on that later .........
 
The alcohol didn't "fix" the knobs, it simply removed the rubberized coating.

This is is also common with Ferrari knobs/switches and even GMC SUV's knobs.


I suggest discussing the knobs with the Customer, before proceeding
 
Does IPA remove healthy rubber or only oxidized/compromised rubber? I've used it countless times on *other* rubber applications and it always stopped removing rubber after it cleaned off the "dead layer".

Never used it on those radio knobs though. I had the same sort of issue on the one Audi's radio knobs, and I cleaned those with Griot's Rubber Prep and then treated them with Sonus TTG+, seemed to work fine and they still feel like they have the rubber coating.
 
I believe that in many cases the damage is done by APC type cleaners.

Be be careful wiping any interior surfaces that are faux chrome with IPA. It can cause the film to bubble up and separate if some is left in a crack or on too long.

What ever...I consider them fixed and perfect unless they become sticky again!

I dont beleive it removed the coating because I did not see any black come off on the towel I used.
 
Good to know. Thanks DC.
I cant say it will be a fix for everyone who has sticky nobs but its sure worth a shot and simple enough to do .

Just to give people an idea of what I am talking about it feels as if someone applied honey to the nobs and they have a wet look to them!
 

Heres the video in case the alcohol doesnt work. He claims after 3 years they are still good.

Warning for foul language! If the video is removed I will understand . ;)
 
Had a VW Jetta with 5 sticky gooey radio nobs the other day. Seemed to be loaded up with some kind of dressing but no other parts were sticky.

I used the 91 % alcohol and it worked but it was more time consuming and a lot harder to deal with because they didnt pull off like the Porsche.

In the end they cleaned up very nicely.

/QUOTE]This is what appeared to happen on the recent Jetta, after the junky gooey stuff came off the underneath part was unaffected.

The Porsche was a different story . It was as if the alcohol transformed the stickiness back to normal .Thats why I referred to it as magic!:)

Had same problem with Masaretti knobs/buttons

I believe it is the new plastic outgassing into the coating Ferrari uses over top the plastic, eventually turning the coating into goo.....No other car maker that I know of puts a coating over brand new plastic in a vehicle. It is usually just colored ABS plastic to match the interior...

I'm looking for a fix for Maserati "sticky"...suggestions welcomed...

The Daughters car had sticky rubber moulding at the Drivers side window. It has been quite a few years but I think I used Dlux and that solved the problem. That piece of rubber rarely gets touched like radio knobs so the longevity thing may not work. Might be worth a try if there are no other remedies tho.
