I clean solar panels with deionized water only, from a hose, and I never touch the glass. No brushes, no squeegees, no scrubbers. Just a mineral-free rinse that leaves nothing behind.
How Do You Clean Solar Panels Without Scratching Them?
By not touching them. A hose rinse with deionized water is my entire method. Because nothing drags across the glass, there is nothing to scratch, and because the water has no minerals in it, there is nothing left to spot or film over as it dries.
What Is Deionized Water, and Why Does It Matter?
Deionized water has the dissolved minerals taken out. Ordinary tap water in Utah County is full of them, and when it dries on a panel the minerals stay behind as spots and a film. Deionized water dries clean, so the panels look right without any wiping.
How Do You Stay Safe on the Roof?
- Slip-resistant roofing boots for secure footing
- A roofer’s block hooked over the ridge, so my full boot has stable support on the pitch
- I never stand or put weight on your panels, or on your gutters
- My footing is always on the roof shingles, a ladder, or the ground
How Often Should Solar Panels Be Cleaned in Utah County?
It depends on the dust and pollen around your home, nearby trees, and your roof. Many homeowners clean once or twice a year, often after the spring dust and pollen. I would rather tell you honestly that yours can wait than clean them too often.

What is deionized water, and why use it on solar panels?
Deionized water has the dissolved minerals removed. Tap water leaves mineral spots as it dries, and those spots can leave a film on the panels. Deionized water dries without leaving anything behind, so the panels are clean without wiping.
Is it safe for someone to be on my roof?
I take roof safety seriously. I wear slip-resistant roofing boots and use a roofer’s block hooked over the ridge for stable footing. I never stand on the panels or put weight on them.
How often should solar panels be cleaned in Utah County?
It depends on dust, pollen, trees nearby and your roof. Many homeowners clean once or twice a year, often after the spring pollen and dust season. I will tell you honestly if yours look like they do not need it yet.
Can I clean my own solar panels?
You can, but it means climbing onto a roof, which is where the real risk is. Plain tap water and the wrong tools can leave spots or scratch the glass. Check your panel manufacturer’s cleaning guidance either way.
Do you clean ground-mounted panels too?
Ask me. Roof access is where my process matters most, and I will tell you straight whether I can do your setup before I quote it.
Do you serve my city?
I serve Utah County and communities within about a half hour of Salem, including Lehi, Saratoga Springs, American Fork, Eagle Mountain, Spanish Fork, Payson, and Nephi.
