I will use it again
August 13, 2013
This product works. It's been a month since I used it, and the mildew smell hasn't come back. I didn't get any results with first can, because I didn't know how my A/C works. After emptying the whole can into the vents, I had some liquid dripping on interior carpet, which was a sign that vents weren't open. Long story short, turn the engine on, turn A/C on, set it to central ventilation, and then turn the engine off. This will leave duct system open, so you can reach evaporator core. My A/C system has 2 motor regulated gates installed 2 inches apart (which stay open only if you turn engine off while A/C is running), plus a plastic screen between them and vents, so i had to make a small hole on it. You may need to remove dash panel around vents in order to see what is inside (recommended). Then just use a can.
