suzuki98 14 Report post Posted April 22, 2007 what do you guys use to wash concrete? I tried simple green concrete formula and it was pretty descent. Was wondering if you guys make up your own mixture? Share this post Link to post Share on other sites
0 Paul Kassander 26 Report post Posted April 23, 2007 Power stroke works well it has degreasing properties and will help release the buildup form the surface. I will use a oxcillic when I am done to brighten the concrete on occasion as well. Share this post Link to post Share on other sites
0 Craig 111 Report post Posted April 23, 2007 Sodium Hydroxide, Sodium Metasilicate, Trisodium phosphate, phosphoric, muriatic, oxalic and citric acids. Gotta know what you're doing with the acids. Keep asking questions! Start out simple and get to know everything about what you're using. Powerstroke works well as well as R-109 and R-202 from Delco. If you mix these in hot water they work even better. Share this post Link to post Share on other sites

Sometimes just water is enough, unless you have oil or other kinds of stains Hey Craig, how's it going havent seen much of you around here. how biz Jeff Share this post Link to post Share on other sites

0 sjpressurewashin 64 Report post Posted April 24, 2007 I Xjet Ox, only takes minutes and its real easy $$$$ when do you xjet? after the concrete is dry or while it is still wet? also do you rinse ox or just leave it? thanks in advance michael Share this post Link to post Share on other sites
0 MMI Enterprises 289 Report post Posted April 24, 2007 Most leave it on concrete as it makes crete whiter as the sun hits it. Most rinse it off wood though as it's main use there is to neutralize the alkalinity of what was used to clean it and to get rid of the gray dead wood.

0 douseahouse 21 Report post Posted April 24, 2007 i was going to start a new thread but i think this one is already helpful. i got a call today about cleaning about 3500 sq ft of concrete. i am told that this was once a transmission shop and there is oil and grease that needs to be removed. i have not seen it yet so i'm sorry that no pics are available. right now i'm trying to get a "heads up" on this and i appreciate in advance any input you guys or gals have. thanks, rando Share this post Link to post Share on other sites
0 Craig 111 Report post Posted April 24, 2007 I would do this job only if you have reclaim, filter systems and flocculants. All that oil and grease down the storm drain is a huge NO NO. Share this post Link to post Share on other sites

0 MMI Enterprises 289 Report post Posted April 25, 2007 Depending on how old, etc. it might have built in sump in the facility. What they doing..turning it into a convienance store or some such? If so, sell them on a whole package of oil removal and then diamond grind it down for them to install their new flooring...just an idea :) Share this post Link to post Share on other sites

0 MMI Enterprises 289 Report post Posted April 25, 2007 can someone help out with this?thanks, michael First it needs to be decided how strong you want it. Like how many oz. per gal . Then you have to work it into what draw rate your xjet gets based on your machines gpm. Think a 4pm can get 2 gal per min. and a 5 like 1.6 gal per min. or some such.. Got to test it really.. I just flojet it on my self. You can use the formula info found below to try and see if xjetting brighteners will be strong enough for crete : ... worked on some ratio formula here: http://www.thegrimescene.com/forums/residential-pressure-washing/10204-12-5-sh-quesiton.html ..or xjet specific here: House Wash with an X-Jet, with recipes for outstanding mixes!

0 sjpressurewashin 64 Report post Posted April 25, 2007 okay maybe i asked the question wrong. what i meant to ask is how strong of a solution should you use on concrete? whats considered to strong? and at 6gpm how strong should my mix be in a 5g pail if i wanted to clean some rust off concrete? Thanks again, michael Share this post Link to post Share on other sites
