A hot water nozzle does not spray any harder than a cold one — heat adds no impact force at all. What it adds is thinner grease and faster chemistry, and that single distinction decides whether heat transforms a job or quietly burns diesel for nothing. Heat is the third lever on a pressure washer,
To power wash porch structures without wrecking them, work top-down — ceiling, then railings, then floor — and treat the floor as painted wood at 500 to 800 PSI through a 40-degree tip rather than as bare decking. That order is the whole article, and almost every porch guide skips it, because almost every porch
Soft washing brick comes down to six things: saturate the wall with plain water first, mix a solution landing near 1% chlorine with a surfactant in it, spray it on at no more than about 50 psi, keep every square foot visibly wet for five to ten minutes, never let it dry, and rinse until
You can pressure wash inside car cabins in exactly three places — removable rubber mats, a rubber boot or cargo tray, and a stripped metal load floor with its drain plugs out — and the rest of the interior is not a pressure washing job at all. That is a shorter list than the internet
A ladder saver nozzle is a large-orifice soap tip that throws cleaning solution forty feet or more from ground level, and the number that decides how far it actually goes is your machine’s GPM, not its PSI. That sentence is the entire product, and it is also the part the listings skip. The tool is
Can you pressure wash brick? Yes, if the mortar is sound. Learn the scratch test, safe PSI by house age, and when to skip pressure completely.
Cleaning concrete with TSP works on grease, soot and chalked paint, and does almost nothing to rust, efflorescence or a cured paint film — because trisodium phosphate is an alkaline builder, not an acid and not an oxidiser. It attacks fats. That is the whole job description. So it is not a general concrete cleaner
Electric vs gas pressure washer, decided. Real PSI, GPM, noise levels, 5-year running costs, and the few jobs that genuinely need a gas machine.
Cleaning cedar siding is a chemistry job with a rinse on the end, not a pressure job — softwood tops out around 500 to 600 PSI, an oxygen-bleach cleaner and a soft brush do the work in twelve to fifteen minutes, and the machine, if it comes out of the garage at all, is there
What PSI pressure washer do I need? Match 1,200–3,200 PSI to cars, siding, decks, patios and concrete safely, plus why GPM matters more than you think.
