Let’s not over think this. Picking a wet-wash product to clean the aircraft isn’t much different than selecting one to clean your vehicle. If you trust it on your cherished Harley-Davidson or show-car paint and accessories, there should be equal confidence using it on the Bonanza. It should be gentle enough to hit everything, including the Plexiglas, not have corrosive properties and rinse off easily.
But there are an overwhelming number of aircraft-specific wet-wash products to choose from. Do a search for wet washes on popular aircraft supply websites and you’ll understand. Wet washes are just that—dilute the soap with water in a wash bucket and go to town with a wash mitt or mop. Suds are a must.
