Hello to all,
Since I cannot use even any mild acids on a softer/porous stone like tumbled travertine, I was thinking of any good cleansing agents along w perhaps a very stiff rotary brush to use w a cordless drill. I have a host of wire brushes, but since travertine is probably not receptive to harsh abrasions, I will seeking some advice on options to clean up the stone. It also seems the problem is more evidenced on the side of the pool that receives less sun. The westside facing sun pool line has less of an issue.
I have kept my pool chemistries in check and have never had a high CA except when the gunite was curing. I just had to add some Ca bc the level was 180; I took it to 250.
Thank you very much.
