Simple Green - SMP13406 Extreme Aircraft and Precision Cleaner, 1 Gallon Bottle 13406

PROS: See below, but in short, gets the deep stuff and is safe for planes. Smells good. Strips wax down to the paint. CONS: Strips wax down to the paint. At $17+/gallon, it’s expensive (yes, I know it’s a concentrate). Leaves a film if you’re not careful. As a concentrate, you have to mix it yourself and have a separate bottle. It's not quite as good as Windex at melting bugs, but I guess you shouldn't be using Windex on aircraft aluminum anyhow due to the ammonia content. CONCLUSION: Any plane owner, without a doubt, should have this in their arsenal of cleaning supplies. THE STORY: I own three aircraft and I like to keep them sparkling clean. I have several cleaning agents that I use regularly, including: Windex, Plexi-Glass Cleaner, Goof Off and good ol' 100LL (plane gasoline). Windex is great for the bug guts. Windshield gets the Plexi-specific cleaner. 100LL for the oil/belly spray and Goof Off for the really hard to remove stuff. I use this sparingly as it likes to take paint with it... So I bought the Simple Green to see what, of the above, it could replace. My initial results, even in high concentrations, were not spectacular. Also, it leaves a surface film I wasn't impressed with. So there it sat on my shelf for five months, rarely used. Now, however, I have seen the light. I had some staining in the paint that a) I couldn't figure out and b) couldn't remove. None of the above products would remove this rainstreak-like staining that was on my tailcone. Even a coat of cleaner-wax wouldn't touch it. So I loaded up a new spray bottle with 1:2 concentrate of Simple Green Aviation. I could not believe the results when it ate right through it and left perfectly clean, bright white paint. So white, in fact, that it makes the rest of the plane look dull. So then I attacked directly behind the plane's exhaust tips, an area brown with grime and exhaust spray. This I’ve, after several repeated attempts at removal, always assumed was permanent. Well, it did take five applications (and wipings) of Simple Green 1:2, but it finally came out. I then quickly wiped the entire fuselage of the plane down and oh man does it pop now. So, in the proper concentration (and repeated applications if necessary), this definitely does the job when even caustic agents won't. I'm a believer now, for sure.

Love it. It works well on aluminum an metals suseptable to etching. It cleaned well and did not etch any metals. Would buy again!!

Great for cleaning stainless steel part

This is the STUFF! Good at tackling belly grease on the airplane and I haven't noticed any issues with it when diluted properly. This one bottle will go a looooong way.

The soap worked great for cleaning my aircraft, but some of it sat down in the wing and caused mew corrosion i didn’t have before. Same spot on both wings. They tapper down and would drain to that point. I sanded out and retreated the area and next time ill be sure to wash and dry the areas throughly. Just be aware that it can cause corrosion if left unwashed

Worked amazing

I use this in my ultrasonic cleaner for aluminum motorcycle parts. Works very well. Doesn’t etch or dull the metal. Works well as a general parts cleaner.

Really effective degreaser. Bought this to clean and degrease my mtb chains and it worked great. This stuff smells even better than the original green stuff. More cost effective than big name bicycle specific cleaners.

Awesome cleaner that isn’t as corrosive to delicate metals as super clean. I needed something that I could soak my intercoolers in for at least 12 hours without it being too harsh. I did go around after and used a bit of super clean as a quick spray-on rinse-off spot treatment but Overall if you’re looking for something non-corrosive and leaves no residue behind for delicate metals then I would recommend

Works great for cleaning / degreasing chainsaw parts in my parts washer. I'm doing 1 gallon of Simple Green to 2 gallons of water. On the back of the bottle it suggests 1:3 ratio for a heavy duty cleaner but I'm more than happy with the results using 1:2 ratio. Will buy more in the future

I use it with 1 part to 5 in a ultrasonic cleaner 40 khz for cleaning rf connector adaptor and it worked perfectly. As a ex-avionic technician it was an easy choice. Read instructions sometime less is more...

I’ve been using the original Simple Green solution for my remote control car/firearm parts when used with my ultrasonic cleaner. It works ok, but very harsh odor when not used in a ventilated area. This solution works perfectly with a 3:1 ratio, but without the harsh odors. Pricey, but worth it. Would buy again.

I had aluminum siding put in and installers did a messy job with all kinds of stubborn stains on the aluminum. I needed a product that would clean well but also be safe on the paint. Everyone just says soap and water but it doesn’t work. This stuff worked amazing. Was shocked how easy it cleaned. Very happy I found this product.
