The Ameritech Knowledge Base is operator-grade content on commercial pressure washing: equipment selection, chemicals, surface-specific cleaning, maintenance, and how to start a pressure washing business. Written by people who build, repair, and operate this equipment in the real world. Free, no email gate, no fluff.
Most operators think PSI is the spec that matters most. It isn't. GPM (gallons per minute) is the spec that determines how much surface you can clean per hour, and most commercial jobs are won or lost on production rate, not pressure. Here's how to spec a machine for the work you actually do.
Read the ArticleWhat pressure washing actually is, how commercial operators think about it, and the difference between residential gear and the equipment professionals use every day. Plus: complete system setups (skid vs. trailer, turnkey configurations).
Read →The specs that actually matter when choosing a commercial pressure washer. PSI vs GPM trade-offs, when to spec hot water, gas vs electric, plunger pump brands, and how to match a machine to the work you do most. Plus custom trailer and skid build basics.
Read →Sodium hypochlorite (SH), surfactants, degreasers, acids — when to use each, mix ratios, dwell times, and safety. Includes coverage on Sticky Icky, Bad Ass Degreaser, Pink Power, Wood & Deck Cleaner, and Purple Power. Real chemistry, real applications.
Read →Concrete, roofs (soft wash), siding, decks, commercial flat work — each surface has its own specs, chemicals, and technique. Plus commercial cleaning applications by property type (retail, industrial, food plant) and recommended frequency.
Read →Daily, weekly, and monthly maintenance schedules. Symptom-to-cause troubleshooting (low pressure, pulsing, hot water issues, chemical injection problems). When a repair is worth it vs. when to replace. Pump rebuild signals.
Read →Equipment investment, startup costs, profitable job types, pricing structure, and ROI math. What's realistic for a one-truck operator vs. a fleet. Insurance, licensing, and the typical first-year revenue trajectory. Honest numbers, not coaching pitch.
Read →Driveways, parking lots, commercial flat work. Surface cleaner technique, SH dilution, oil stains.
Read Guide →Asphalt shingle, tile, and metal. SH-based soft wash, pressure ratings, surfactant use, dwell.
Read Guide →Vinyl, wood, brick, stucco. Pressure trade-offs by substrate, soft wash vs power wash, mold and algae treatment.
Read Guide →Truck and trailer wash, transit vehicles, RV and dealer detail. Hot water spec, recovery considerations, throughput.
Read Guide →Pressure washers, pumps, parts and accessories, surface cleaners, hoses, and chemicals — the Ameritech catalog.
Shop Equipment →Authorized warranty repair, pump rebuilds, and full-service maintenance at the Tampa facility. Ship in or drop off.
Schedule Service →Custom trailer rigs, skid systems, hot water builds, and reclaim configurations. Built in-house at the Tampa shop.
Spec a Build →Call the team. Ameritech techs and salespeople have been speccing, building, and repairing this equipment since 1988. If your question isn't covered in the KB, it's not because we don't know — it's just not written down yet. Phone is faster.
