My sister had her pool replastered, they were brushing as required but it appears the black plastic on the top of the brush left a few marks on the seat edge of the spa, any suggestions for removing the black marks? Plaster is about 2 wks old, yep, I told them to be very careful, lol.

They could try brushing it off :poke:

Or maybe gently using some wet dry sandpaper. Although I might suggest you ask the plaster company what they would suggest

Our fairly new white plaster is constantly getting black marks along the edges from the robotic cleaner. Brushing alone will not get rid of the nasty marks.
I use dish washing scouring pads and it worked for me. Can't wait for the 68F water to warm up so I can scrub the black marks in the deep end.
