Review: ITS A ACID read the instructions!!! - Works perfectly , cleans coils bit read the instructions you don’t want to over use .
Review: Great product, pretty potent stuff - Great product, pretty potent stuff. I manned-up and used it with shorts and without gloves. Every now and then a drop would fly on my skin and quickly started to burn. No marks or long lasting affects. I did the heavy use 1:4 ratio and mixed 3.2 cups of this with 12.8 cups of water into my 1 gallon sprayer. I went nuts and used the whole gallon for one application. After I sprayed it into the crevices it started to foam up. I sprayed the inside too for the heck of it. After a few minutes the foam started to look brown as it carried the dirt out of the cracks. About 15 minutes later I rinsed it all off with water. After putting everything back together and turning on my A/C, man I tell ya that thing is many times quieter than it was before. I've had to open the door to check that it's even on. It was getting louder and louder as each month passed. You kind of get used to it since it's a slow progression of noise. The motor can work less and cool more efficiently. I'm sure it'll show in my electricity bill. What led me to getting this product is that the compressor kept itself off after overheating while the fan was still turning. I came home and the furnace was still circulating inside air but it was warm at 82 deg. I ordered the product then luckily the day it came the compressor/fan was so loud we had to turn it all off so the neighbors wouldn't complain. Last season I used a $5 can of cleaner from the local hardware store. Did it's job for one season. But from now on I'm using this product every Spring.

## Questions & Answers

**Q: Can this be applied with a garden type pump sprayer? Or does it need a special sprayer?**
A: The Product is corrosive and a the SPRAYER NO 50P POLY (4770-0) should be used, however if it is for a one time application and you wash the sprayer thoroughly after use, you should be fine.  please confirm that the plastic on the sprayer is durable and not susceptible to corrosive elements.

**Q: What are the main differences between nu-brite and cal-brite?**
A: I believe Cal Brite can be used on an indoor evaporator cool, while any Brite can ONLY be used on the outdoor condenser.

**Q: How to get it to foam?**
A: Put it in a spray bottle with water and spray with a thick setting, will self foam......caution use gloves eye pro.....it burns skin.....fully rinse after set time

**Q: What is shelf life?**
A: According to the manufacturer: Indefinite
