What does chalked mean? It means a painted surface has begun shedding its own colour as loose powder, because sunlight has broken down the resin that was holding the pigment in place and the pigment now has nothing to hold onto. Run a dry hand across the wall and a pale version of the house
You can power wash a sidewalk with the same settings you would use on a driveway — around 2,000 to 3,000 PSI, a 25-degree tip or a surface cleaner — but three things about a public footpath make it a different job: you probably do not own the concrete, the runoff has nowhere to go
A soft wash spray gun is a low-pressure, high-flow valve and nozzle assembly — typically rated somewhere between 100 and 360 PSI at 5 to 18 GPM — and it is the exact inverse of the pressure washer gun it superficially resembles. That inversion is the whole reason the part exists. On a pressure washer,
Cleaning fiber cement siding means a garden hose, a soft nonmetal brush and a side-to-side stroke in the direction of the plank — and if a pressure washer comes out at all, James Hardie’s own care guide caps it below 1,500 psi, through a wide fan tip, from a minimum of six feet away. Six
Vinegar for cleaning hard water stains genuinely works, and it is the one outdoor cleaning job where it does — because the white crust is calcium and magnesium carbonate, and acetic acid converts carbonate into a salt the rinse water can carry off. That is a strange sentence to write on a site that has

How to remove mildew from outdoor pillows, honestly: the cover is a thirty-minute job, the core is a three-day one, and if you only do the thirty minutes the speckles come back before the cushion has finished drying. That is the entire article in two clauses, and it is why patio cushions have a reputation
The piece of roof cleaning equipment that decides whether the job happens is the ladder, not the pump. Everything that sprays is cheap, well documented and easy to choose. Everything that gets you and the spray within range of the shingles is expensive, dull, and the actual constraint. That is not how the category is
Swimming pool algae stain removal is two separate jobs, and a pressure washer only owns one of them — the deck, the coping and the tile band at the waterline are flatwork and clean like flatwork, while anything living in the water itself is a chemistry problem belonging to whoever looks after the water. This
The power wash vs soft wash question is really two arguments wearing the same coat. In the trade, power washing means heated water and pressure washing means cold — that is the entire difference, and it barely touches a homeowner. Soft washing is the one that matters: not a low setting, but a cleaning solution
