Best chemical solution to use with a pressure washer?

WenchOtheW

I will be using a pressure washer for the first time to clean concrete sidewalks and building exteriors for a large condo association. What cleaning solution should I use? Keep in mind I am trying to be cost efficient as well and I will most likely require several gallons. Thanks.

Answer
I just use bleach. It's diluted so much you can't smell it and it seems to work fine on the mold and dirt that accumulates in Florida. You have to soak the building or sidewalk first, then go back over it with high pressure. There's also Rust Out, or mix a solution of Iron Out. But bleach is the cheapest and usually the high pressure will be enough to clean whatever needs to be cleaned and you also want to be environmentally friendly.

Answer
If you are talking about mud from dirt, high pressure washer should be sufficient. Careful about chemicals; some could be harmful to surrounding plants or grass.

high pressure washer has very little pressure?

lemondrop

2400 psi....used to have to hold the gun with both hands now I just go along with one hand on the nozzle and it takes FOREVER to clean just the walkway and I have to practically touch the cement to get it really good. There is a white, green, red, and yellow attachment. The red works really well but is pin point (draw your name type) and would take a REALLY REALLY long time to do anything. Any suggestions. I'm obviously not very technical so I would appreciate detailed information please and Thank YOu Very Much!!!! Engine runs fine just little pressure.
It's gas powered if that makes a difference lol

Answer
This could be several things....possibly the seals, or you may need to check the pump oil. Go to Sears, they sell pump oil, as well as several products designed to lubricate the pump and clean it as well. The attachments you describe are the different nozzle tips for various spray patterns. Do you run any chemicals through the unit?? If so - make sure that they are approved for this type of use, and NEVER run bleach through the unit (unless you thoroughly flush it out afterwards). You might also want to carefully dis-assemble the wand and make sure that there are no mineral deposits blocking anything. Check the water inlet screen (where you attach the hose, there should be a screen) make sure it's not clogged or blocked. Finally, consider using a chemical to "help" the pressure washer do it's job....for concrete, Home Depot carries gallon sizes of "Rust Aid" - use a pump-up garden sprayer, apply the Rust-Aid, let it "work" for 5 or 10 minutes then blast it off with the pressure washer.

How do you clean a metal roof?

pressure washer chemicals image

kmisa

I have an industrial size pressure washer (the kind that has to be hauled on a trailer). We have only had the metal roof for about 1 1/2 year and I am afraid of damaging it with the pressure washer. What chemicals should I use and is there anything natural that can be used?

Answer
Hire a professional to avoid chemical and water damage to your home. The money spent for a professional will outweigh what you could end up with in repairs!

How to clean an older wood swingset?

pressure washer chemicals image

me&2kids

We recently acquired an older (10+ years) swingset/fort thing. It's pretty rough, but still works. My biggest issue is that there seems to be a layer on the wood, but I'm not sure what it is. I don't know if the wood is pressure treated. When the wood gets wet, this layer seems to come off and make my daughter's clothing all dirty. What should I use (chemicals/pressure washer/scrubbing) to clean that awful layer off? Any advice would help. Thank you!

Answer
Chances are the wood is treated, that's good...you stated something coming off the wood, I would guess it is mold or mildew. I would pressure wash it to get as much as i could off(please be careful with the pressure washer at 2500psi you can cut Thur wood and other things,OK? then i would use a bleach& water mix about half&half in a garden sprayer, wearing very old clothes spray the entire set ,this should kill anything growing on it, let the mixture sit for a short time about 5min and wash again,make sure your childern&pets are out of the way,wash your garden sprayer very good hose too ,bleach will eat thru rubber washers, let swing set dry,and seal it with U.V. protected sealer this will help with sun damage.they also make an aditive to prevent mold&mild add to sealent,if you can........hope this helps you!!!....it probily would'nt hurt to hose down the entire area after you bleach

How do you clean off the dirt and silt from landscaping rock?

happee

We just bought some new rock and used the jet setting on the hose to clean it off, but it still seems like there's some stubborn grime on them. I don't think a pressure washer will work much better than the jet setting.
Are there any chemicals (Natural or synthetic) that clean them off? Vinegar, maybe? We don't really want to take 1.5 tons of rock and do the whole wheelbarrow, sifter, water thing.
Please help! Thanks!

Answer
There is a product that cement companies use to remove cement from tools and unwanted areas but I do remember the name (its caustic!). Mineral spirits will work and can be found at a local hardware store.

What is the best chemical/substance to use to clean the green off my sidewalks using a pressure washer?
Thanks.

Answer
Bleach works. That green slimy stuff is mold. It grows everywhere in FL, you can't leave anything outside. It should be our state flower, lol.
