I don't own a pool, but have a question regarding pools.
I am currently taking lessons at a instructor private backyard pool, I am not sure when the pool was built but the house was built in the 30s and renovated in the 50s
After the 1st lesson, my hands and feet are stained blue from peeling plaster? on the bottom/sides. I been trying to get the blue stain off and it doesn't seem to be coming off completely. Should I be concerned about this as I'm not sure what materials/chemicals is in the stuff and I don't need any health issues down the line.
