My friend told me recently that anytime she needs to
peel up something sticky (in that case, she was removing a peel-and-stick tile floor),
she blasts it with a hairdryer first.
Today, I tried it with some product labels that have been stuck to my garbage cans for months and it worked! Easy peasy. Chemical- and liquid-free!
Works on stickers, too (in case someone in your household likes putting them everywhere...). :)
