Coil Cleaning

Do you have a product to equal or replace Simple Green?
Yes, our Green Clean will easily fill that need; in fact, it has been found to be a better cleaner than Simple Clean.

How can I improve the cleaning process in order to make the coils stay cleaner longer? How can I protect the coils?
Use of the Teflon-based coil protectant, Cal-Shield, will help the coil to repel moisture as well as dirt, grease and grime. It will help the coil to stay cleaner longer, and the next cleaning will be very easy. Cal-Shield also provides protection for coils operating in aggressive or acid environments such as walk-in food coolers and salt air environments.

I’m cleaning an air-cooled condenser and I want the best foaming and cleaning product you have. What is it?
So long as the condenser coil is located outside or outdoors, use either Foam-Brite or Nu-Brite.

Regardless of foaming characteristics or formulation types, what is the very best cleaner you have?
That would be Special HD CalClean. It is an excellent degreaser and cleaner, and it contains the best surfactants or wetting agents and the best corrosion inhibitors to protect system metal. Also, it can be used to clean electronic air cleaners as it is effective versus nicotine tars. It can be diluted 20:1 or even 40:1 and used for a wide variety of coil cleaning and general cleaning.

What can I use to clean an evaporator coil in a "no-rinse" application?
You may use Evap Pow’r or Evap Foam - No Rinse. The first, Evap Pow’r, is available in two forms: a concentrate, Evap Pow’r-C, that should be diluted 3:1 and a ready-to-use product, Evap Pow’r - Rtu. Evap Foam - No Rinse, is an aerosol product that delivers a fast-breaking foam to the coil surface for excellent "no-rinse" cleaning.

What considerations should I have when cleaning condensers located on rubber roofs? Which of your products are safe on rubber roofs?
The most common types of rubber roofs are Modified Bitumen, both Coated and Uncoated, and EPDM-Type roofing. And the only one of the three that would be a concern is the Coated Modified Bitumen as it contains fibrated aluminum. Therefore, those cleaners that foam and brighten the aluminum fins or those that are quite strong in concentration should not be used on this specific type of roofing material. Instead, cleaners like regular CalClean or Tri-Pow'r should be used...

Which of your coil cleaners are biodegradable?
