Top 7 Common Mistakes in House Washing—and How to Avoid Them

1. Using the Wrong Cleaning Chemicals

Mistake:

Not all surfaces are created equal—and neither are cleaning chemicals. Using a harsh acid or bleach on sensitive materials can discolor or degrade them.

Solution:

Use surface-specific cleaners like F9 BARC for rust removal on concrete or F9 Double Eagle for degreasing and neutralizing. Always check the product label and do a patch test.

2. Skipping Pre-Wet and Dwell Time

Mistake:

Spraying chemicals and immediately rinsing without letting them work can waste product and deliver poor results.

Solution:

Always pre-wet surfaces (especially concrete and delicate materials), apply your cleaner evenly, and let it dwell for 5–15 minutes—unless specified otherwise.

3. High-Pressure Washing on the Wrong Surfaces

Mistake:

Blasting wood siding, stucco, or shingles can strip paint, destroy materials, and cause leaks.

Solution:

Use low-pressure soft washing techniques on delicate surfaces and reserve high-pressure washing for driveways and stone. Always match the PSI to the material.

4. Ignoring Safety Gear and Chemical Handling

Mistake:

Skin burns, respiratory issues, or worse—all from skipping gloves, masks, or eye protection.

Solution:

Always wear PPE (gloves, goggles, respirators) and ensure you're using the right dilution ratio. Store chemicals like F9 products away from children and in cool, ventilated areas.

5. Cleaning in the Wrong Weather Conditions

Mistake:

Sun-baked surfaces cause chemicals to evaporate too fast, while rain can dilute them.

Solution:

Clean on cloudy days or early mornings/evenings. Avoid direct sunlight and windy conditions that can blow chemicals into unwanted areas.

6. Not Protecting Surrounding Plants and Surfaces

Mistake:

Overspray can damage plants, discolor windows, or etch glass.

Solution:

Cover plants with plastic, pre-rinse landscaping, and always rinse windows immediately after spraying chemicals nearby.

7. Poor Equipment Maintenance

Mistake:

Clogged nozzles, cracked hoses, or leaky tanks reduce efficiency and lead to uneven application.

Solution:

Check your equipment before every job. Flush systems regularly, inspect seals, and replace worn parts—especially if using powerful products like those from LNI Equipment.
