Grouting stains

Postby spanishcoach » Thu 30 Apr, 2009 05:59

Chrlorine and PH levels are OK. Have scrubbed away the marks on grouting several times and brush walls twice a week. But the marks keep on returning.

What can I use to keep the grouting lilly=white. Have tried Copper sulphate and then a a "starver" and use chlorochoc on the floor, but walls are impossible. Pool is around 28C and I use a bubble cover and cubierta until weather warms up.

Suggestions please.
