Silicone is very difficult to remove. It must be carefully scraped off using a tool that will not damage the surface below. I have found small plastic scrapers in kitchen stores that work not too bad.

But even after mechanically removing as much as possible, there is still the residue left behind and a small amount of the silicone.

Only after physically removing as much as you can use a product such as Chris above mentioned.

Do not use acetone! It will damage all surfaces and take the paint off. Acetone is ok only to make a final pass with a well wetted rag of it, and only to take off any final residue of oil, dirt etc. Do not rub or scrub with acetone. A quick wet wipe, and then let it evaporate. And acetone will not dissolve silicone. Silicone is uncured rubber. Once cured there is not much that will break it down.

Silicone has its place, but NOT in the exterior sealing of an RV! Why people insist on promoting the use of this crud baffles me.

In 45 years of the solarium / glazing / renovation business I have earned a serious heap of money tearing down and replacing rotten sunrooms that were sealed with silicone.


Well said, Sillycon is not only the wrong product it is the worst product that can be put on an RV. Tried several of the magic elixers for silicone removal,, if they
work it is not silicone.

Will acetone take off the paint? It's painted aluminum.

Depends on the paint. It won't affect automotive paint, but it will strip automotive repair paint (go figure)
