Aggregate surface cleaning

[Aggregate surface cleaning]

Hello,

How do you go about cleaning aggregate concrete? Do you use a concrete surface cleaner? If so, do you have to move the surface machine faster? What are the best chemical mixes for a downstream injector? The one I am dealing with has alot of algae on it. Thanks in advance for your help!

[Question on used pressure washer]

Hello,

I found a used pressure washer for sale, but since I am fairly new to the biz, I was hoping to get your opinions on whether this is a good setup and price. The other concern I have is the trailer only being a single axle. Would that be strong enough to handle the weight of the machine plus a full 230 gal. water tank? So, here are the details...

All-American 3500 psi hot/cold pressure washer - $7500

* 3500 psi, 5 GPM, hot/cold All - America Pressure Washer (model # PH5035HGOD)

* 8'x5' Single Axel Trailer

* 2 Hose Reels

* 100' supply hose

* 200' 3/8" High Pressure Hose

* 230 Gallon Poly Water Tank

This machine is like brand new and its heavy duty. It only has about 20 to 30 hours on it.

Thanks in advance for your input!

Mike

[Chemical info]

Hello,

I have a commercial grade pressure washer and am thinking about putting it to work for me, but would like to get more educated on the various chemicals, applications, etc. Can anyone recommend any books or other resources on this subject? Much appreciated.
