If you're using this to clean a window/through the wall A/C, unless you physically remove it, move it outdoors and use a garden hose (with a powerful spray attachment) to flush the accumulated crap out, using this can of foam is a waste of time and money! The only thing that it does is loosen up the dirt/debris on the surface of the coil. I love the reviews where people spray it on the surface of the coil, wipe it off (or use a toothbrush or other type of brush), and pretend that it's nice and clean! That's superficial nonsense, since the entire coil needs to be flushed out! It gets clogged from front to back! Trust me, if you use a powerful water spray (steam cleaning is even better), you don't even need this can of crap! Just brush the surface dirt away and blast it with water!....but make sure to cover the motor and electrical component box with plastic as a precaution!

I'm just glad I didn't jump on the Walmart deal. I'd have gotten something else to get over the $35 free shipping limit (or bought 8 cans? 😬).

Better this way.
