I have a customer who would like me to clean this wall for him and possibly the entire outside of the warehouse. This is just a wall that lines the entrance. There is some mild along the top and whit streaking all along the bottom. What do the experts suggest I use to get this clean? The customer would like to keep the cost down as much as possible because it's just rental propertyImageUploadedByTapatalk1316619456.215731.jpg

House wash mix on the brick will clean the dirt and kill the mildew.

I would use one restore (safe restore)or another acid cleaner on the white efflorescence at the bottom or on the whole thing.

Just be sure not to mix any bleach with the acid cleaners it is BAD!
 
The white streaks may not be visible after the wall is cleaned and you may not need the acid. If you do, heed the previous warnings. Be careful though. You might find the acid etches that wall and leaves it looking whiter at the bottom than the top...then the bottom will get dirtier quicker...
 
Thanks for all the advice I'll try a strong house wash mix first and see how the wall turns out. If all else fails I have plenty of acid around the shop I can use on the white streaks. Any suggestions on an acid dilution ratio?

Also they want the warehouse floor cleaned as well. A moving and storage company will be moving into the building so he wants the floor clean enough that they can sit grandmas couch on it. I posted a picture of it. There was a hydraulic line repair company operating out of it now so there's sone oil on the floor. I was thinking maybe presoak with a heavy degreaser and running over it with my vacuum surface cleaner to reduce the amount of water on the floor. Any input would be greatly appreciated on this job as well.

Dads doing great thanks for asking AC. Playing as much golf as possible before it starts getting cold out. Keeps me pretty busy with doing bids and still handling all of our graphic removal jobs. I just got hit yesterday with 50 tractors to deidentify, detail interiors, and two step the outsides. Best of all not only did it get dropped on me last minute they need it done by October 1st. Plus they hit me with a big list of trailers to do as well. So things are busy for me which Is good. Keeps me out of trouble.

How are things with you?

For acid dilution, it depends on what you buy. I believe 30% is roughly what we buy now. We get great results at a 10:1 ratio, but we find 16:1 to work on most applications.
As for the floor, I'm sure some flat work guys can chime in with great advice. I would suggest your favorite degreaser and high heat! If that doesn't give you the results you want, you can try that acid (after rinsing very well!) at the 16:1, then 10:1 ratios. 10:1 will likely etch the concrete which is ideal if you plan to paint/seal it after it's clean! I've had limited success removing hydraulic oil stains...
 
Ok thanks for the response kyle that's about the dilution I was thinking. I've cleaned a lot of concrete but have never really gone the whole restoration direction before so I'm just making sure I'm doing things right to get the best outcome. I know some of these guys on here can take a just plain filthy oily greasy mess of concrete and make it look new again.

That floor has a shine look to it, or it could be the lighting or a bay door looks open or something. Better check to see if it's been sealed and of they sealed OVER some or all of the fluid. I have seen warehouse floors where they tried to get it clean and then just seal right on top of it.
