Benziene is good , as is meths if there are significant gum deposits – benziene is a little nasty as prolonged exposure leads to cancer , meths is problematic if the pex is stressed from flame polishing as it can lead to stess cracks, If there is NO gum left after stripping , then use warm soapy water.

I was always told that IPA may damage some perspex.

I use a citrus based product which works a treat, then polish it off with warm soapy water.

The citrus cleaner is not abrasive, and removes the glue and everything else.

They use it a lot for cleaning shower screens etc if you are looking for some.

Only looks like a small panel Dex, why not save yourself the grief and just sell them a new panel complete ?
Failing this, I use either white spirit or Rapidtac adhesive remover but as the others have said, be careful of polished edges causing crazing.

thanks dsi nigel for the replies
would love to do a new panel but i think it would cost out too much simpler to replace the graphic i have quoted £50 which i think is reasonable not too much so i can get a foot in the door new customer
i am very wary of cleaners we used a one at work for years i think it was caled MEK supposed to be safe 😮 we have a citrouse based cleaner at the minuite calld citosol removes glue from metal etc but will remove paint and anything else basicly paint stripper but smells like oranges 45 is there anything specificaly for perspex (if thats what it is ) i will give them a ring and see if a spec sheet is available they will probably reply 😮 what thanks again

If you are sure it is perspex and not polycarb then just use cellulose thinners, cleans and degreases at the same time.

We use the Citrus based stuff. Got to watch it doesn’t have an adverse reaction to the perspex as it does with some plastics. i.e melting.

John the best way is to hold the sheet, polycarb is a bit more flexible and if you knock it with your finger it has a more plasticy vibration to it. Sorry to sound a bit silly but if you have a piece of each and do this to each piece in turn it will become clear very easily.

😕 🙄 (?) (?) (?)
