How Detergent Systems Work
Not all pressure washers deliver detergent the same way. Using the wrong system can damage your pump or deliver ineffective cleaning. For homeowners in Hialeah and across South Florida, understanding your detergent system prevents costly mistakes.
Detergent Delivery Methods
- Downstream injection: Draws detergent after the pump at low pressure (when using a low-pressure nozzle). Safest for pump longevity — this is what professionals use
- Upstream/direct injection: Pulls detergent through the pump. More concentrated application but can damage pump seals with harsh chemicals
- Onboard detergent tank: Built-in tank on consumer models. Convenient but limited capacity and often poor mixing ratios
Detergent Types by Surface
- Sodium hypochlorite (SH): Best for house washing, roof cleaning, algae/mold kill. Must use downstream only
- Sodium hydroxide (SH/caustic): Heavy degreasing for commercial and parking garage cleaning
- Oxalic acid: Rust stain removal on concrete — never run through a pump
- General-purpose detergent: Safe for most consumer washer tanks. Good for cars, outdoor furniture, and light patio cleaning
Chemicals to Never Use in Your Pressure Washer
- Bleach (undiluted) — destroys pump seals and hoses
- Muriatic acid — corrodes pump components instantly
- Dish soap — creates too much foam, can overheat pump
- Any chemical not labeled "pressure washer safe"
