Product good but screw on cap leaked badly. not great for doing a plane belly because of this.

With the use of this product on aluminum, I dont have to worry about corrosion to my airplane, as this product is really good at removing grease, oil and bugs. Just mix as recommended and spray on the affected part or place that needs cleaning, this product works very well.

Best cleaner on the market, bar none!

Excellent cleaner

The BEST product to use on the belly. Ive tried it all. Kerosene, Gasoline, 100LL, Goof Off, Windex, you name it. Most of the fuels (kerosene, gasoline) will immediately cut the oil and grime from the belly, but deeply set stains will often linger. This, to not even mention the health hazard of using fuel as a cleaner. Exhaust stains (right past the stack) are particularly stubborn. Simple Green is the ONLY product Ive found that cuts everything belly related. Now, its not my #1 choice for bug guts (thatd be Windex), but for the grime, its Simple Green all the way. Pro-tip. I find at most a 1:1 mix works best. However, I typically use it straight out of the bottle, in a 2 gallon grass killer pump sprayer from your local big box store. Caution: It wont damage professionally applied aircraft paint, but it WILL blister cheap spray paint. Ask me how I know.

Excellent - this product is great, I may stop the traditional bath and dry to using this product and some wax.

Best cleaner I have used. Works well on the belly.

Great product and customer support !

Every hangar needs simple green! Its safe for the environment, and more importantly contains no harmful solvents that can damage your planes finish! I keep a gallon in my hangar to refill the 32 oz spray bottle and use it after every flight to keep my composite leading edge free of bug debris! Works well, safe to use, a hangar staple!

Aviation branded Simple Green... Carries the required certs so mechanic shops are allowed to use it legally. Cleans the undercarriage of the plane the same as normal Simple Green does, just has the words Aviation written on it. It works, not much else to say!

Gentle on paint and plexiglas. Tough on dirt.

Works great to cut oil and grease on aircraft surfaces.

Great non corrosive cleaner specifically for aircraft use.

Extreme Simple Green is the best degreaser I have found for cleaning the belly of our C182!

I am not one to normally write reviews, but then it is not often that I come across a product like this. Simple Green Extreme is absolutely positively the best bug blaster that I have ever used. I mixed it 3:1 and used a spray bottle from Loweâ??s, and the moment you spray it on you can watch bug guts dissolve before your eyes. This stuff is absolutely amazing, and in the same dilution is a super belly degreaser. Best aircraft cleaner I have ever bought and believe me, I have spent tons of cash on cleaning products for my planes over the years. I wish I could give it more than 5 stars.

Best product for cleaning the aircraft belly that Ive ever used.

This cleaner does a very good job of cleaning oil and exhaust staining. It also did a very good job of general cleaning of the entire underside of my plane (bugs, tar, etc.).

pretty much does what its suppose to.

works wonderful

Best product Iâ??ve found for cleaning lead and oil scum from the aircraftâ??s belly.
