salt stains on stained concrete from salt water pool

gma_jJune 27, 2011

We have stained concrete all around as the sitting area around our salt water pool. We are getting a lot of white salt water stains on the stained concrete. Would you all give me advice as to how to remove the white stains? Thank you so much for any advice.

If they don't wash away, it's not salt but likely calcium.

Scott, thank you for the info. How do we get rid of calcium stains?

Usually diluted muriatic acid, 3 or 4 parts water to 1 part acid. Always add acid to water when mixing, rubber gloves, goggles, knee pads, acid washing brush... Wash it down with water loaded with baking soda to neutralize the acid. Pour any leftover mix in the pool and rebalance a couple hours later.
