how to best use pressure washer

7 years ago

I'm moving on from my previously posted garage floor 'what to do' conversation. Today I found pops old power washer / pressure washer that has not been used in years.. since he passed. However the fact that it was stored with no gas in it had me optimistic it would work and sure enough it started and worked.

I hosed out my garage earlier today with it. The reality is I need to buy some kind of cleaner ..clean it then etch and seal it.

Upon using the power / pressure washer I noticed it left lines in places. see picture. I guess I'm wondering is there an attachment or a proper way to use this tool or are you supposed to put down some kind of chemical and let it loosen before I washing.

I am not so much concerned with the way the floor looks I really just want it cleaned and . But seeing these marks on my floor sort of tells me I must be using a pressure washer incorrectly ....so before I buy some kind of cleaning solution and give it another go any thoughts on what I might be doing wrong?

We bought this attachment for our power washer and it works great. My husband cleaned our deck, driveway and sidewalks with it. It is well worth the money.

Hey Max Muller, the most important thing is to know how exactly pressure washer works. If you know this, the possibility of the damage will be practically zero. I know it because I had very similar situation. My last gas pressure washers had left the same trail on a surface that I cleaned. It took a lot of times to find out what I have done wrong. I can share with one article, that helped me a lot with the information about the best gas pressure washers. It helped me find that my last gas washer had too much pressure and didn’t have the necessary attachments. So, I decided to change my gas pressure washer, and to choose the other one. I bought the Generac OneWash 6602, review about it I found exactly in this article. Today I don’t have any problem with pressure washer and with cleaning.

It looks like your pressure washer is set to produce a narrow stream. You should set it to a fan shaped stream then advance it like it's a scraper.
