Ideas on how to clean wax off walls?

[the old grind]

After the credit card scrape to remove thick portions, use charcoal starter, naphtha, or odorless mineral spirits as a solvent to clean up for paint. Cotton rags work best vs synthetics, and you just need to dampen to get a feel for how little it might take to clean up what size area.

If you're repainting a wall with crayon marks on it, skip the scraping and just wipe/scrub as needed with whichever solvent. You might see a blush from some dark colors, but bleed-through won't happen and paint will adhere well.

btw, trim any of those junk mail credit cards made out to Joe Smith into narrow, notched, radiused, etc scrapers for 'those times' the tool drawer doesn't have the right thing to hack in with, or you don't want to scratch paint. The next time you take a bar off a chain-saw, you may see places to use them. They wipe off easily, and don't take up much space in a case.

Are you old enough to remember the ink wells in our desks?

Shucks I even had to use them!
