Repairing white haze on sealed concrete with Xylene. 

Where did you get the pump sprayer? Yes, you should be very happy with the clean up.

Never seen xylene in a plastic container. Only a metal container

What did you do to clean out your sprayer after using the xylene?

I have one particular patio my company did a stamped concrete patio. No matter what temperature, how dry, how low humidity, it seems there's always white cloudy spots all over it. This is the only patio we've had this reoccurring problem on. Is there a product other than xylene you can recommend? We've tried xylene many times, still same problem. Had it sealer sandblasted off and resealed. Same problem. Any advice on a product for unusual circumstances?

Nothing is more irritating than a how to youtube video where the guy is having a grade 9 essay minimum word requirement fken flashback.

all that and you didn't show us how to do it? I'm confused

One word of advice. That mask is not suitable at all. A proper full face or half face mask with organic vapor cartridges is what you should use as the chemical is cancerous.

Useless video. Instead showing the working steps it keeps showing for 5 minutes the concrete surface,
