Polymeric sand residue

Cleaned a paver driveway for a customer last week. He called today to let me know that there was a white residue on the pavers that he can't hose off. I haven't looked at it, but suspect it is from the polymeric sand.

What is the best way to remove the milky residue?

Could possibly be sealer. A guess and only a guess! If you used hot water. Possible hot h20 and or the chem broke down liquidlifing the paver sealer inside the sand. After cooling and drying it resealed on top the pavers. If you figure it out please follow up

Customer says he didn't have them sealed. He has a bucket of the sand. It's made by quickkreet. Going over there tomorrow with some acid. If anyone has had this happen, let me know how you fixed it.

Pressure takes it off, we have used a turbo nozzle the last few times we did it. Your going to end up removing allot of the sand in the process.. Sounds like it wasn't installed correctly in the first place.. I have never seen it installed correctly so no surprise there. Once that stuff gets wet for a few minutes it's starts to get soft and ends up lifting a little easier. Bring some regular joint sand, and some seal n lock and sell them on properly stabilizing the joints. I'm not a big fan of polymeric. But there are some here that have success.. My margins are way better using regular sand and sealer and in my opinion is a more permanent solution. Once the sand is sealed you can hover the pavers the following year and not worry about lifting the sand. Good luck Al, start hydrated:)

Lots of water and a turbo nozzle did the trick. Been a long time since i used that thing.

Actually I don't do the sanding and sealing. I think the guy that did the paver job sold him on poly and not sealing. This is a regular customer of mine. I clean his roof and home on a regular basis. We'll see how this plays out in subsequent visits. At least I'll know to lock and load the turbo nozzle next time.
