If you’re outsourcing, the cleaner is only as good as the company using it. Here’s how to choose top exterior cleaning companies:
1. Check Their Cleaning Solutions
- Ask: “What cleaner do you use for vinyl siding?”
- Look for: Biodegradable, vinyl-safe options like Mold Armor or Krud Kutter.
- Red Flag: Companies using no chemicals and high pressure—too harsh for vinyl.
2. Verify Experience and Expertise

- Look for: Several years experience; specific vinyl knowledge.
- Example: A company with plenty of jobs under their belt likely knows the best cleaner for pressure washing vinyl siding.
3. Read Reviews and Testimonials
- Check: Google, Yelp, or their website for feedback.
- Look for: Mentions of cleaner effectiveness and siding condition post-wash.

4. Assess Equipment and Methods

Soft washing (low PSI) with adjustable washers—safer for vinyl.

What’s the best cleaner for pressure washing vinyl siding?
The best cleaner depends on your siding’s condition. For light dirt, Simple Green Oxy Solve is gentle and effective. For mold or mildew, Mold Armor E-Z Wash targets organic growth fast. Krud Kutter House Wash excels with tough stains like rust. Look for biodegradable, vinyl-safe formulas with no harsh bleach—top exterior cleaning companies often use these and others. Test any cleaner on a small spot first to ensure compatibility.
Can I use bleach to clean vinyl siding with a pressure washer?
If not diluted properly, it can fade or discolor vinyl siding and harm plants. Let the experts make that call. Instead, opt for oxygen bleach (like OxiClean) or commercial cleaners with controlled bleach levels, such as Mold Armor. Professional exterior cleaning companies typically avoid straight bleach, favoring safer alternatives like soft-washing solutions.
How do I know if an exterior cleaning company uses the right cleaner?
Ask directly: “What cleaner do you use for vinyl siding?” Good companies will name specific, vinyl-safe products like Simple Green or Krud Kutter and explain why they’re effective. Check if they prioritize eco-friendly, biodegradable solutions and avoid high-pressure methods that could damage siding. Reviews mentioning “no damage” or “great results” also hint at their cleaner quality. A pro’s expertise in choosing the best cleaner for pressure washing vinyl siding sets them apart.
What PSI should I use with a pressure washer for vinyl siding?
Stick to 1,500-2,000 PSI for vinyl siding—higher pressures (above 2,500 PSI) can crack or dent it. Pair this with a 25- or 40-degree nozzle for a wider, gentler spray. Exterior cleaning companies often use soft washing (low PSI with specialized cleaners) for safety. Always start low and adjust up if needed, keeping the nozzle 2-3 feet from the surface to avoid harm while using the best cleaner for pressure washing vinyl siding.
