Hey guys, I'm on a g/f/s job and have come across these strange marks...
Tried screwfix degreaser, pink stuff and a bit of bleach. Cant budge them. I spoke to the home owner as I thought it might be some kind of sealer gone wrong but he built the house himself and says its nothing he is aware off. ?
Any ideas?
