AeroCosmetic Belly Wash and Belly Soap loosens grease and dirt better than Extreme Simple Green recommended by Cessna. The comparison is not even close. Cleaning the aircraft belly of breather oil is a snap. No rubbing required. Belly Soap is somewhat effective in removing exhaust deposits on the belly but it requires multiple applications, soaking, and rubbing. It is not very effective on long term exhaust deposits. It is really effective on dirt and oily deposits inside the cowling.

Wow this shuff is Amazing!!!

Best stuff I have ever used. Works every time.

This stuff really works!

I only clean the bottom of my plane once a year and this does the job. I use a soft brush to clean around all the rivets and then wipe it clean. It has become my general cleaner when I work on the plane.

This stuff seems to work! Got the exhaust stains off my new paint that I couldnt get off with other cleaners. It wasnt spray on wipe off but was pretty close and it did the job way better than anything else. For the greasy belly I sprayed it on liberally, agitated it a bit with a rag then pressure washed it off and it was spotless!

Easily removes exhaust stains that seem impervious to other products or even varsol.

Great for removing exhaust stains. Apply, let set for a couple of seconds....wipe off. I always keep a half gallon in the hangar.

I keep buying because it works and doesnâ??t irritate me in the process.

Works great removing oil from belly of aircraft. Spray it on, let sit and wipe off!

Cleaning the belly of the plane has always been a dreaded job. Ours was getting pretty bad. This product was recommended by a hangar friend. We were pleasantly surprised by the ease and the results when we used this stuff. Itâ??s goes on easily, you donâ??t have to use much, not a lot of scrubbing and wipes off easily.

Great stuff! Gets off oil & gunk debris from the belly & leaves a slick shine.

This stuff is amazing. I have used many different products for exterior cleaning and never had any thing work this well.

Best cleaner for the under belly of your airplane. Nothing else is better!

My favorite underbelly cleaner. Easily dissolves lead deposits and oil on the belly. I use as a dry wash for the bottom of the plane and any other place oil streaks. I wear a mask and safety glasses. Better than breathing droplets and getting them in my eyes.

I just used this on my Archer and had to come back and write a review - this stuff is great! I could not believe how easy it made the job of removing years of accumulation! Honestly, I think the plane is lighter, now! ð??

Hands down the BEST solution for cleaning my airplaneâ??s belly that I have found in the past nineteen years that I have owned it. This stuff works GREAT! I just cleaned mine yesterday and the oil and grime just wiped right off using paper rags from a box. Quick and easy!!!
