When repairing a plasterboard ceiling in a kitchen after running some cables, I managed to drip mitre fix glue all over the worktop. Tried wiping it off with a rag, but that made it worse, now the worktop was covered with solid hairy glue. I tried everything to clean it off, acetone, isopropyl alcohol, upvc cleaner, you name it, nothing worked.
Out of desperation, I sprayed some of the solvent for cleaning the expanding foam gun on it, and gave it a rub with a rag. And it worked! A bit of elbow grease required, and had to keep spraying it, but it brought the glue off a treat, and no damage to the worktop itself. The client need never know!
Feeling pleased with myself, I noticed a few more drips on the washing machine, next to the program dial. No problem, I gave it a good spray and went to work with the rag. And all the writing for the various washing programs around the dial came clean off, rendering the washing machine useless!
