Lubegard 96030 Kool-It Evaporator and Heater Foam Cleaner (2 Pack)

I followed the directions and sprayed this into the AC drain after I used a small snake to unclog it. This took away the mustr odor coming out of my AC. The foam smells like chemicals which took my about 3 days of blasting my AC with the windows down, but now the smell is gone. Overall 5/5 for what it is. Recommend.

if you need to clean the evaporator coil in your car, this is possibly the best product to use. I have used this is 3 cars in all the different methods. Firstly in a Mini or any car where the ac drain is easily found and accessible, just feed the tube up as high as it will go from outside the car and empty the can. Wait 15-20 minutes and then turn the ac on on the lowest setting and let it run for 10-15 minutes. The smell is nice enough i drove the car to the gas station to fill up with just my window open to let the condensation wash out the residue. Secondly in a car where you can access the evaporator from inside e.g. tesla, you can remove the air filter, poke the hose into the evap chamber and empty the can in there. Wait 15-20 mins until the foiam dissolves, pout the filter back and run AC on low as before. Lastly where you can't do the other methods, then find the most central vents and poke the hose down there as far as it will go. Again empty the can, wait 20 mins and then run the ac. In this 3rd case you may need to turn on the ac on the lowest setting, set the air distribution tot those central vents to open the internal flaps when you feed the hose in. Once its in, turn off the AC leaving the hose in place. At that point empty the can in there and follow the rest of the wait and then run the ac process. e.g. some Mercedes have the drain hidden above the driveshaft so this may be an easier way to get it done. Note that for me the Mercedes needed 2 cans as i had not done it for 10 years.

Was skeptical on using it. But went through the air vents instead of other route. Followed the instructions and within maybe two through three days had a cleared water vent. Plus the fragrance wasn't that bad either.

For cleaning out the evaporator, left it smelling really fresh! The only downside when I first used this product was the foam kind of leaked out of the cap I pressed down on - so a small amount of it got on my hands. Other than that, really simple to use and good value for a two pack!
