Surface cleaning...

[Mark0012]

Hello
I would like to know, if I should apply detergent first with a wand then pass over with surface cleaner... or do just dont bother with the detergent. Just dont want a bubbly mess on the sidewalk.

Suggestions please

Unless the surface is excessively filthy (filthy enough that it wont come clean with just heat and pressure) i myself would just use the surface cleaner without chemical.

Unless there is a stain on the concrete that will require the use of a chem (and which chem to use is determined by what the stain is) and assuming you have a machine capable of cleaning concrete, I would clean the surface first, then treat the areas that need extra attention. Be sure to not allow your run-off to get to a storm drain - especially if you are cleaning oil and/or are using a chem.

(storm drain) ; even if your using biodegradable chemicals safe for the environment?

My understanding of the Clean Water Act is:
Nothing but rain down the storm drain.

We prewet surface, apply a sodium hydroxide product (F18), clean with SC, and then mist oxalic or SH when done. Beautiful every time.

No such thing. Nothing down a storm draid but rain water.

Try not to get caught up in the hype around "Green" Chemicals. You'll waste money and also time because most don't work very well anyhow. The key to being "Green" is in the steps you take to be responsible. It is all about the proccesses and methods you use.

The absolute worst thing I hear constantly from the manfg of "Other" chemicals is how bad bleach is. Yet it can be bought at Grcery Store from a shelf easily accessible by toddlers and then used on folks under garments. It is al about the person handling the bleach or the proccess in which it is used. House Mothers know exactly what I mean when I say that they know how to use the Bleach safely but not to let the teenage boy do the Laundry.

More than anything you do, you will need to understand chemicals and procedures to set you apart from the guy down the street with a truck with four different tires trying to convince customer that his "Bio-Degradable-earth-friendly-green" product is better than your professional knowledge of your SAFE system.
