Advanced HVAC Coil Cleaning Fin Brush for AC Evaporator and Condenser Coils – HVAC Coil Cleaner | Stainless Steel Pins - Improve HVAC Efficiency, Easy AC Maintenance - Double Sided

This brush is a must when cleaning any evaporative coil or radiator. On one side is a good set of nylon bristles which won't damage aluminum fins if you use them carefully. And on the other side are fine, wire bristles with rounded tips. The handle is a black plastic of sufficient size to feel good in your hand. Using a foaming cleaner, you can use the wire bristles to brush with the "grain" of the coil's fins and get deeply embedded gunk out, while a second pass with foamer and the nylon bristles cleans the fins almost completely and without damage. Remember to always pull the bristles along the "grain" of the coils, never across. This brush worked well and for the cost was outstanding. It's robust enough that I expect it's the only one I'll ever buy (unless I lose it), but if I needed another I would re-order this one.

I've cleaned four different window a/c units with this brush and it still is holding up! It probably isn't going to last for a long time. But it has been a good buy so far.

The scrapper could be a bit sturdier but overall cleaned my a/c coils very well

Worked great for cleaning my AC units.

Works great I used them to clean the rv and home ac’s easy to use and really cleaned the ac’s

Works great for cleaning cottonwood fluff from coils.

Small very small don't be fooled by the picture it's like 3" wide and 4" long no joke !!!! Literally almost worthless!!!!

Worked great removing hair and dirt clogging the fins.
