What product will get rid of dried on glue on upvc windows ?

[S101]

Put velcro up for blackout material.

Have found that the velcro comes off put leaves all the dried glue behind.

Is there a product I can put on to rid the glue quickly ?

if on the glass, use a razor blade, it will get rid of anything in glass, if on upvc frames, then VERY carefully try using nail varnish remover and a lint free cloth

try using a upvc cleaner ... they sell it in homebase or b&q I think!

or maybe white spirit/meths?
