I have seen people speak of STORM DOOR CLEANER ... what exactly is that ? I went to home despot and the only stuff they had was something called JOMAX ? I have a couple intakes with oxidation I'd like to clean up. I have used eagle one etching wheel cleaner but I need to dip these intake to get the inside also and at 7 bucks for about 14ozs it's going to get real expensive.



Sounds the same as coil cleaner that you use to clean you home AC unit outside.

I have used it on aluminum with good results and a pressure washer to remove. Don't leave it sit too long.

I also have used this stuff many times also before painting aluminum, it's basically the same as coil cleaner.
Spray it on after diluting it with water, inside and out and power wash it off, works good for me.
