Hi, I am redoing the second bathroom in my house and am wondering if anyone has a good idea how to get this adhesive off the plaster wall behind the tile. On my other bathroom I tried scraping and was not effective at all so ended up knocking walls down. I’d like to avoid demoing walls in this bathroom as it is used by a lot more people and hate the mudding and sanding process.

Weird outlet by breaker box. Hi all I thought this outlet was a 240 volt for a dryer but then looked at it more and tested it with a 3 prong dryer cord and it wouldn’t fit. Any ideas? This is an older pushmatic breaker box also if that helps
