How to Choose and Use a Pressure Washer

There’s something undeniably therapeutic about pressure washing, and as a homeowner, it probably constitutes my favorite of all of the home maintenance pastimes. At least, it’s right up there with lawn mowing and mulching, both insta-gratifying. Just check out this slo-mo video—if that doesn’t get you excited about pressure washing, I don’t know what will.

We bought a new pressure washer this season, a 2700 max PSI gas-powered model (an upgrade from the little electric 1200 PSI model that I’ve had and appreciated and actually loved for nearly 5 years). The new washer is one tough cookie and a great addition to our outdoor arsenal. After reading many reviews and actually talking with people who own and appreciate more-powerful pressure washers, I was plenty certain in my decision to buy, and I picked up my own at the store last week for spring cleaning.

A pressure washer is great for cleaning any number of surfaces (even canvas and outdoor furniture cushions, but I started out by cleaning the unpainted back wall of my cement block garage, a surface prone to growing moss and unidentifiable grime.


Step 1

Step 3

Angling the water also helps with backsplash, keeping you dry and clean of debris as you make your way along the wall. You’ll begin to see the transformation immediately, especially if your wall is as filthy as ours was.
