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.

I use this to clean my firearms. It works great in an ultrasonic cleaner. However, just a little word of advice, even though it's safe for plastic. Do not put your eyeglasses in it.

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.

Used Simple Green Extreme Aircraft to clean dried ethanol out of my aluminum dirt bike carburetor. Used a 3:1 ratio in an ultrasonic cleaner and it worked wonders. Heated the mixture to 110F and it didn’t etch the aluminum.

This works great for cleaning all sorts of automotive parts, engines, rear diff covers, etc. Just mix it per directions in a good spray bottle and clean up your vehicle so you can spot when something starts to go bad, don't leave it dirty and be surprised by a big leak you could've caught much earlier.

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

To my knowledge, this is the one simple green formulation that is safe to use on bare aluminum. It works well on all surfaces and all greasy messes. We have at home including the kitchen. We are a regular repeat customer of this product.

I did 6 tests in my ultra sonic cleaner using old 2JZGE pistons Normal Simple Green (on foam piece) This Extreme Aircraft Simple Green (on ground) 3:1 ~24ounces water : 8 ounces chemical 15 min, 30 min, 1 hour (right to left) (bottom to top) Creworks 30l at 50 Deg C For sure don’t use normal simple green, it left oxides even after quick rinse and dry and not “sitting” outside of the ultrasonic I do not see any kind of pitting. These are cast pistons so the roughness is from casting.

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

We use this cleaner on everything around the house. It is concentrated so you don’t need much.

This is a great product. I specifically use it to clean firearm parts in an ultrasonic cleaner. It is safe for use on aluminum and other non-ferrous metals (follow the dilution instructions!!!). Cleans pistol barrel ramps and C8 bolt carriers like a charm! Cuts through carbon and powder residues. Best of all there are no harsh solvents or fumes. It does not leave any residue as long as you use it correctly. Instructions are easy, they are right on the side of the jug!

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.
