PetraMax Solar Panel Cleaner Solar Spotless (Makes 166 Gallons) - Super Concentrated Glass & Solar Panel Cleaning, Remove Oils, Fingerprints & Water Spots - Solar Panel Cleaner Concentrate (32 oz)

This is the best cleaning solution I've ever used. I put 1/2 oz. in 2 gals. of water and used it with a soft bristle brush (one used for washing cars) on the solar panels. Bird droppings have been a persistent problem ever since I installed the panels. Almost as if the birds are having a contest. Using this chemical, almost instantly, the bird droppings began to dissolve. With 2 or 3 more light swipes, the droppings were off the glass. These same droppings hardly dissolved at all when using water and a spray nozzle. Another plus, it also greatly reduced visible water spots that have been on the panels for some time. Out of curiosity, I also tried this for washing my car. The results were amazing. Using a soft brush, this solution even removed brake dust from my wheels, which usually takes a much stronger chemical. It dissolved bird droppings that had been on the car for over a week in the sun. Water alone, even with scrubbing, wouldn't even touch the droppings. And again, water spots that had been on the windshields for over a year were visibly reduced. I've tried all sorts of other chemicals to remove water spotting, but nothing has worked as well or as easily as Solar Spotless. With minimal effort, my car looked great. Almost like I had just taken it to a car wash. With minimal effort, I can maintain my solar panels in pristine condition. I highly recommend this product.

I bought this to clean off some of the solar panels that are on the roof. I found that to get the panels clean, then you need to scrub them once you spray in this cleaner solution. Luckily, I have a telescoping pole that I usually use to clean gutters that I can attach a soft brush to the end. I was able to use that to reach a couple lower panels. We have a 2-story home and I was unable to reach the higher panels. So, the product wasn’t useful for getting to clean those. If you have panels you can reach with a scrubbing brush, then this cleaner will work for you.

Best shipping and it includes the solar panels really nice

Unable to make a decision. It didn’t work on my old flag pole light. 4 yrs old . Did I wait to long to clean it ?

Work great. When I need more in will buy it again.

This product work great on your solar panes. A+

This past year I have been experimenting with lighting that is solar powered. Well it is that time of season where aphids are dropping their honeydew all over everything on my deck and patio where I have the lighting setup. Pretty much covering up all my solar panel reducing the solar charging capability. Used this product and now we are back in business. Star Rating System (What do my star ratings mean?): 1 STAR - Completely unusable, would request a refund 2 STAR - Meets minimum viable product requirements, wouldn't purchase it again 3 STAR - It does what it should, but in a non-spectacular way, I may recommend it, but definitely with reservations 4 STAR - I like it. It is solid quality and delivers as advertised, I would purchase it again and recommend it to a friend 5 STAR - I love it. It meets or exceeds all of my expectations and is high quality, I would purchase it again and would openly promote it to friends As an Amazon Vine Member, I give honest reviews, whether or not it is a good one or a bad one.
