FYI: Powerwashing Dry Rock Results...

[Erosa911]

Just a friendly FYI:
I saw a while back in a forum to never powerwash your dry rock because it will "blast it to pieces"... shwell, I braved through it and gave it a shot anyways and the results were phenomenal to say the least! I've posted a before and after picture too, all my rocks turned out white again and sparkly clean. Hope this can help anyone in the future.

In case you were wondering, all the algae that was previously on it was actually sun baked for about a week and was impossible to brush off in the sink, thus I resorted to this method. This isn't intended to be an anti-bleaching post, im familiar with that as well, just thought there are some people who'd prefer assert a little bit of elbow grease into their pride and joy.


(Side note: it does make quite a mess from all the sand and gunk blasting off the rock, but I think this is a much better alternative to bleaching it if you'd prefer to remain chemical free. The biggest piece that broke off during the process was about the size of a quarter, and really it just made some nice rock rubble to put at the bottom of the tank. Power washing was done on about 100lbs combined of Pukani, Fiji, and a few pieces of tonga branch and a 8 inch shelf and took about 45 minutes to complete)

I need motivation to pressure wash the driveway. This might make me get the washer out
