### **Essential Safety Measures Before Using Bleach in a Pressure Washer**

**Never pour undiluted bleach directly into your pressure washer’s tank.** Bleach is corrosive and can damage internal seals, O-rings, and metal components. Instead, always mix bleach with water and a surfactant for optimal performance and safety.

– **Equipment Compatibility**: Check your pressure washer’s manual—only machines with downstream injectors or bleach-safe fittings are suitable.
– **Protective Gear**: Wear gloves, goggles, and old clothing to avoid chemical burns or staining.
– **Surface Testing**: Apply the mixture to a small patch first to avoid discoloration (blending with water helps prevent etching on painted surfaces).
– **Ventilation**: Never use bleach in enclosed spaces—ensure open airflow to avoid inhaling fumes.
– **Rinse Thoroughly**: After cleaning, flush the system with clean water to prevent corrosion inside the pump and hose.

**Pro Tip:** For porous surfaces like wood or limestone, consider a lower concentration (e.g., 1–2% bleach) to avoid damage.

### **How to Apply Bleach Through a Pressure Washer?**

#### **Step 1: Prepare the Bleach Solution**

A common ratio is 1 part bleach to 3–4 parts water, plus a splash of laundry detergent or specialized surfactant (helps bleach cling to vertical surfaces). For better results with hard water: add a water softener like Calgon.

*Example for 5 gallons:*
– 1.5 gallons chlorine bleach (8.25% sodium hypochlorite)
– 3 gallons water
– 1 cup surfactant

**Adjust Concentration**: For graffiti stains or heavy mold, increase bleach (1:1 ratio), but reduce for lighter surfaces.

#### **Step 2: Load the Downstream Injector**

Most cleaners rely on a **downstream injector** attached near the hose end:
1. Disconnect the spray gun or wand.
2. Place the injector tube into your bleach mixture bucket.
3. Reattach everything—the injector will pull chemical downstream, after the pump, preventing corrosion.

**Tip:** If your pressure washer lacks a downstream injector, use a **bleach-safe foam cannon** or a siphon hose rated for chemicals.

#### **Step 3: Apply the Bleach Mixture**

– **Start low pressure**: Adjust nozzle to 60–70 degrees for wide spray.
– **Work bottom-to-top** on vertical surfaces (fences, siding) to prevent streaks.
– **Leave dwell time**: Let the solution sit 8–15 minutes (moisture helps activate bleach but don’t let it dry).
– **Avoid over-application**: A thin, even coat is effective; puddles waste chemical
