HELP: Removing unwanted silicone gel gunk


SupraStar 3000

Recommended Posts

I've used silicone gel to fix some acrylic sheets (with applied vinyl tint) to a fiberglass substrate,.. but accidentally got some silicone on the face of the transparent acrylic (quite a lot actually doh).

 

Thinking it would simply roll off like Copydex glue with rubbing i let it dry, but now only small patches of silicone will roll off, the thicker lumps seem to have bonded really well, its taken me hours just to clean up a small area.

 

I want to try white spirit or thinners but I'm worried it may react with the acrylic or vinyl tint and dont have any material left to test on. I really dont want to f**k it up as its cost me £100s to get this far.

Thinners will burn and cause miniscule cracks to the acrylic if its too strong.

 

Heat often helps but you have to be careful how you go about applying heat. Can you not just pull the lumps off with pliars and then rub the stuff away? An acrylic scraper?

Very difficult IMO.

 

Did you try using Kleenex, like usual then? ;)

 

:D Nope. Not even Kleenex gets this crap off

 

I can go and put some thinners on a bit of acrylic here if you want, see what it does

 

Cheers mate - much appreciated

its the vinyl tint that i think will melt
