Hello. Long time lurker. Been researching the forums here for about 6 months and want to thank everyone for the great information!
Just finished surface cleaning this residential driveway with terrible staining from pool company who backwashed pool across driveway a couple years ago. Homeowners said the pool was very acidic and caused the pool heaters to burn out twice within a short time.
We tried F9 BARC, F9 efflorescence and F9 groundskeeper with no great success. Purple power diluted and surface cleaned with 2000psi 25025’tips on 16” wisperwash with 4K/4gpm machine.
The customers were satisfied and understood that the driveway was damaged from the pool company’s neglect.
What would you have tried to get better results? We are always trying to improve outcomes.
