When using soap or other detergent in your pressure washer it can be troublesome to determine what the best soap is to use with your pressure washer. I will try my best to tell you guys what products work best in certain situations. Using the information below you can see what works best based on my recommendation.
What is the best general purpose pressure washer soap? – My go to soap for my pressure washer is a jug of ZEP. It is fairly low cost and they make task specific cleaning solutions. When it comes to cleaning my concrete driveway I use the ZEP 128oz Driveway and Concrete Pressure Wash Concentrate.
What chemicals are safe to use on a concrete driveway when power washing? – Like I said before I like to use the ZEP Driveway and Concrete bottle. I have also used Simple Green but I think that ZEP does a better job. To apply it you just spray it onto your driveway and wait 20 minutes. Make sure that it does not dry out so you may need to re-wet your driveway if it is really hot outside. After 20 minutes wash it off and your driveway will be a lot cleaner than it was before.
Please note that you should take precautions with your grass. Make sure to wet your glass before hand and after you are done so that the soap does not kill the grass.
Can I use soap or chemicals to clean the outside of my house?
What detergent should I use to clean mildew? – Borax Soap works well on mildew and is a great solution for cleaning brick. I find that I have a lot of buildup of mildew on the side of my house and using just a pressure washer and water does not clean it very well. You have to be careful with what solutions you choose as you want to be careful not to stain or change the color of the bricks. You are also going to see mildew on wood. When using a pressure washer to clean wood be very careful with the nozzle you choose. Also be sure you are not really close to the wood. We do not want to damage it and too much pressure against wood can leave a bad situation.
What is the best Deck and fence cleaner? – When pressure washing a deck, fence, or other wooden objects, your best detergent to use would have to be Simple Green 11001 Clean Building All-Purpose Concentrate Cleaner. I find that this product works about the same as Krud Kutter DF01 Blue Pressure Washer Concentrate Deck and Fence Cleaner with Sweet Odor, but has a more pleasant smell.
Overall there really is no best pressure washer soap. Sometimes you may need a degreaser, other times you may find that you just need some dish-washing soap. You really have to be more specific with what type of detergent you need to handle the job. Some of the all-purpose cleaners may work for you but it is always best to use an application specific cleaner.
