acorn stains in new gunite pool

[mbar]

waste is right - chlorine will bleach out the stains over time. I get stains from them all the time since I live in the woods Ascorbic acid will not take the stains off. You can either put the chlorine right on the stain, or you can try rubbing the stain off with a "stain stick" or Mr. Clean magic eraser. The stains will eventually go away on their own with the high chlorine. Yes, the acorns stain really fast - I always try to get them out as soon as I see them!
