does anyone know how to remove the fenestration rating stickers?

Hi MrsD, try using WD40 to soak the stickers, let the WD40 sit for a few minutes then the stickers should come off fairly easy. Hope this helps, and good luck!

Goof Off (or similar petroleum based solvents) or even fingernail polish remover (acetone) may also work. You can use a plastic putty knife to get the adhesive off too after soaking the labels. This works at getting off those labels from china and crystal too.

GOOF OFF IS THE WAY TO GO!
