Oxidation or mold on window trim?

Anyone know how to get this crap off?

 

Would like to know also.

 

Looks like mold the way it branches out in circles, but can't be certain.

 

I just cleaned mine up last weekend.
No way near as bad.
I used purple power full strength with a rag and lots of elbow grease.
I then used meguiars back to black.
Again with a cloth and rubbed really hard to embed it. Did it twice.
I’ll get a pic for ya

 

Going to have to do it again.
It was a PITA and 20% as bad as yours



I don’t know, try something stronger like thinner or something?

 

DO NOT USE THINNER!!
@Tacoma Mike no disrespect sir.
I have yet to try it, but I've read that magic erasers work on this. I am experiencing the same problem on mine and just haven't had time to devote to it.

 

Oh hell none taken..
I said I didn’t know but if you know something please share.
Not prob man.....
I remember someone said he was going to try it.
Don’t remember anything after that..

 

Mines bad also. What do you think causes it? I was thinking some kind of rubber mold. I have tried vinegar, soap, rubbing alcohol, nothing really seems to work.

 

I've always killed that mossy mildew shit with vinegar, it wipes off after a minute to kill.

 

Well... I think I'll just try a magic eraser dipped in purple power. Haha!
Thanks yall!

 

303 aerospace protectant will help that out

 

Ajax and a toothbrush. Ajax has bleach in it that helps kill the mold.

 

I shared what I had read on other parts of this forum. I also know that laquer thinner is fabulous for many things and detrimental to others. I've also seen the longer term effects on rubber and plastics and they generally aren't good. I'd hate to see ten of us need to replace that seal because we prematurely dried it out.

I like the vinegar suggestion stated above and would definitely try that. Alcohol may work as well, but would need to see it work, and for me it didn't.
As a detailer I always try to start with the least invasive method and work my way up the "intensity" scale to find a solution.

If we knew for certain what causes many of us to have this same problem it would be easier to hone in on the solution. I would be willing to try some things this weekend, but unfortunately I won't have time prior to devote to this until then.

 

I agree with your logic but a one time test in a hidden place for him might be warranted. That’s really bad.... I see this and I think it’s poss a UV breakdown? Just thinking out loud..

 

we all have it, or gone get it at some point.
for sure

 

After I get that crap off, I’m going to try rubbing in some silicone. Something that will stay awhile and seal the pours in the rubber.

 

I agree with the potential for UV breakdown. I think it's a distinct possibility. The fact that so many of us from the dry hot, to the rainy, to the humid regions have it really support that.

Rubber is porous so whatever is happening is really sinking in and being a real prick about removal. And the marks on the Op's pictures match what I see on my trim. Almost definitely mold, but I'm no chemist.

 

I've used the magic eraser on the black plastic trim with great results, but I've never tried it on the window trim. I'm likely to believe that it will work since it's abrasive. Just be careful of the paint. Maybe tape it off. Interested to see what works though.

 

How to Remove Mold From Rubber
By RACHEAL AMBROSE Updated JULY 17, 2017


When mold forms on rubber, it's important to kill and remove it quickly to prevent long-term damage. Because rubber is porous, the mold may penetrate the surface of the rubber. Eventually, this can cause the rubber to fall apart. Both vinegar and bleach are effective at killing mold. Bleach kills mold faster, but may discolor or weaken the rubber. Vinegar takes several hours to kill the mold, but will not damage the rubber.

 

I have that shit but thought it was because I lived in the humidity capitol of America. Interesting we all have it. None of my non Toyota cars have ever had this mold.
