Cant remove glue from rubber

Hi

I have problem with removing old glue from my rubber. I used Butterfly Free Chack. And i have tried almost everything but the glue just does not come off. I have tried heating the rubber, using tape and tried with fingers. Does someone have any suggestions?

Hi Tom,

It can get quite difficult.  I think heating and using your finger is often the best way.

If it is still quite flat it may be best to just glue over it.
