Stripping water based sealer off exposed aggregate

[deerminator]

So, I over applied it last July and it turned out cloudy for the first time ever. I tried to scrub it off with soap and a stiff brush. Commercial patio cleaner and what not. Just made it kind of splotchy. I figured the best remedy at this point was time. The water based sealer inevitably wears off after a year or so, the aggregate and concrete dull and you have to reapply. But this spring it still seems cloudy. Not sure I want to wait all year or another one for it to wear off. Any tips or pointers? Do I go to some sort of acid wash at this point? Thanks!

Pressure washer maybe?

I may have to give that a shot. My gas powered PW is shot after two years. The appliance repairman from our local home store told me if I get a new one, get an electric one. He said the investment is minimal compared to gas powered and they last way longer. So I may have to buy one and try. Worst case is I have something to wash the vehicles and siding with. Thanks.

BTW, I did everything "right" with the craftsman PW I had bought. I always had the water turned on with a 50 foot or less hose before I had it fired up. Followed all the maintenance procedures and it simply went kaput. Would have cost nearly the same amount to buy as it would have to fix.

Interesting on the power washer. My dad had a few of the electric ones and they never seemed to last. I bought a gasser 3 years ago and it has served me very well but I am sure there are different levels of quality to everything and both types probably have their share of good and bad.

Back to the topic-

I have a pretty strong background in waterbased wood finishes and the solvents for those products are mainly Isopropyl Alcohol and Acetone. Also, I have found that one of the best products to clean the cured finish off the parts of my spray equipment is Simple Green. That is the first product that I would suggest trying and you can test in a small area by applying it mixed with water in about a 20% concentrate ratio. If that works mix 1 gallon of SG with 4 gallons of water in a 5 gallon bucket and spread it across the surface with a squee gee or a push broom and let sit for the day, then hose or powerwash everything off.
