What's the difference between the two? We want to have our vinyl siding cleaned, but I heard that you shouldn't pressure wash it. Is it a do-it-yourself project, or should a professional do it?
I think they are one and the same...
I would just get one of those hose end sprayers filled with a cleaning solution and use that to clean your vinyl siding.
I recently bought a Karcher 1800 PSI 1.5 GPM Electric Pressure Washer at Lowes for $159. It is the greatest thing since the wheel. We have used it on everything from the siding to the side walks. You use it with or without a cleaning agent. If you do use one; Krud Kutter (also from Lowes) works well. The pressure washer is made for the home owner and easy to use. It even did a marvelous job on my picket fencing. I have a three year old set of vinyl wicker - love seat, two chairs and a table. They had become so dark and dinghy I was going to throw them out. After using the pressure washer the furniture is sparkling white again and good for a couple of more years.! That washer has paid for itself already.
Have you found that the pressure washer damages the siding or whatever? Do you have trouble with the water getting up between the boards pr shingles and into the walls?
No we did not have a problem like that. The pressure washer we bought has a PSI of 1800. Commercial power washers PSI is 3000. These high powered pressure washers can cause a problem if they are not used by professionals. It is wise to use a detergent like Krud Kutter and let it sit for a few minutes to loosen the dirt. Then you will using less water for cleaning. I also used it for cleaning windows and it works great.
Are you still enamored by your Karcher 1800 psi pressure washer? We would use it only on our pavers.
changing the head on your power washer can eliminate some problems, and improve cleaning of some things.
