Removed blue coating on ac fins don't buy

Tried some spray foam cans which do nothing, I do know that you have to be very careful with chemical cleaners on evaporators and micro channel coils(car coils) I got this to clean my ac which has never had a proper coil clean in it’s 12 years use(we just clean the exterior with a brush) Spraying on a dry surface did not get much foaming, so wet the coil and there’s a lot of foam it did work to get the dirt out but the residue it leaves behind is a pain to clean and you need to use a lot of water to rinse the coil. I guess this is lye as it left a powdery residue. Do not use a brush and brush while the cleaner is on I tried a small area on the corner and the fins just flaked off. I focused on doing small areas so that I could have the cleaner for under 2-4 minutes and start rinsing that portion and worked in sections to clean the entire ac. Air flow did increase a good amount and I saw a lot of dirt come out which was not visible. It did it’s job however I would not use this cleaner again just as a last resort. This cleaner does give out fumes and make sure to use gloves and if it gets on your skin then rinse it well. Try not to spray the cleaner on the copper bends just on the fins don’t try to get shiny clean just clean whatever dirt it can in 5 mins and rinse off. So far no damages leaving that small portion where I did try to brush. Do not use this on coils which have coating. And if there’s no airflow issues just use water to clean don’t use harsh cleaners For car coils (evap and condenser) try to find a cleaner that’s micro channel safe or an evaporator enzymatic cleaner. Or try their natural ph cleaner(green)

Not bad.

Good product
