Greetings-
Can anyone recommend a safe for car AC condenser fin foam cleaner? Apparently, some cleaners can damage AC condensers.

Do you mean evaporator?

Coil must be cold. Soak it with purple power at 50/50, then rinse like you never have rinsed before. I remove the fans and spend a ton of time reverse flushing it the opposite way.

Do you mean evaporator?

no- the condenser below front bumper and grill. Fins are quite dirty and AC is not as great as it once was. Plenty of 134 in the system and no leaks, good compressor, etc. My first step was to replace cabin filter and now clean those fins. Need a cleaner that is not damaging to aluminum

Just use a spray nozzle

This works well and doesn't leave a chemical odor.

Spray with water/dish detergent. Soak a bit. Rinse pushing out from the inside. Works for me!

Simple Green or Purple Power works well.

Simple Green or Purple Power works well.

Purple Power is highly caustic and attacks aluminum. Simple Green is also not recommended for aluminum surfaces if exposed for more than 10 minutes. Simple Green Pro HD is formulated to be non-corrosive to all metals.

Unless its really packed with dirt just use straight water and hose it out.

And yet here we are 25 years down the road, using Simple Green to clean the AC. No corrosion what so ever.

Just wash it off almost immediately, well may be after 2 minutes wait before rinsing.

I buy those HD spray bottles and do all I can with Dawn @ 25/75 …

think I will do this and a brush- thanks to all for the excellent info.

Don't be too rough with the fins. I had a coworker who blew some out with a pressure washer. He said he got to close

Purple power is really caustic. It'll burn skin. I'd be very weary using it to clean A/C parts.

Yes I have used these. No harm to aluminum. Rinse well with water is the key.
