HVAC Guys - Foam Blaster (18oz.) - Penetrating Coil Cleaner - 3 Pack - For AC and Refrigeration Units - Clean and Deodorize Evaporator (No-Rinse) & Condenser Coils - Neutral Citrus Scent

I took the covers off and sprayed the cleaner on the embedded dirt. This side took an entire can so you will need 2-3 for a large AC. Waited 15 minutes then sprayed water from the inside out. The fins are clean and the AC works like new again. The whole process of unscrewing and removing the panels, cleaning then putting back took about 45 minutes

Great for cleaning out dirt in the fins of my window AC units. Spray all over the coil, ideally into both sides, leave for 15 minutes and then rinse with a low pressure hose. Makes a big difference to the performance and efficiency of the units, and a very easy DIY job every spring

This product cleaned my air conditioner coils perfectly and safely. Would use again.

Worked perfectly. My AC was leaking water from the coils into the pan. This spray unclogged and cleaned the coils in one application. Very easy and saved a call to the AC company. Super impressed.

We bought this in the summer to help clean our AC unit and it worked like a dream. We sprayed it on and let it sit for a bit and then rinsed the ac unit and it was so clean! We had a lot of this fuzz type stuff that had come off the trees so it was helpful in getting that off luckily. The product company is also so great. We did not receive our order when it was expected and it seemed like it was never delivered. When I reached out to the company they re shipped a new order to us right away and I was so grateful. Thanks again and great product!!
