Store description excerpt

Pay once. No subscription, no ads, no account. Works offline. Blast is the pressure-washer reference. Know the PSI each surface actually takes before you etch the driveway or strip the deck, pick the right tip, get the exact nozzle number your washer needs, and mix detergent without gas-station math — every figure cited to its source. Free forever • Surface guide — Consumer Reports pressure bands: decks 800–1,000 PSI, siding 1,200–1,500, concrete 1,500–3,000, and the honest never-wash list (roofs, and yes, cars — CR says paint nicks invite rust; foam or hand-wash instead) • Nozzle colors — what red 0° (avoid it), yellow 15°, green 25°, white 40°, and the black soap tip are each for • Wash Safe — CPSC-cited rules: an injection wound is a surgical emergency, GFCI for electric units, never run gas units in a garage; never spray from a ladder (CR) Blast Pro — one-time unlock • Nozzle size — your washer's rated PSI and GPM become the nozzle number to buy, by the CAT Pumps selection formula, plus your cleaning units (PSI × GPM) • Soap & dilution — the label's ratio becomes ounces per gallon and a total for your mix tank For homeowners with a driveway, a deck, siding, and a pressure washer that came with five mystery tips. $6.99 one-time for Blast Pro. No subscription, no ads, no account. Privacy: Blast collects nothing. No analytics, no accounts, no cloud.
