RE: What is the Best Airplane Cleaner
The Windshield washer does work very well as long as it is the alcohol base fluid.
You can also make up a special sauce on your own for less money.
1 Gallon plastic bottle.
1 Pint rubbing alcohol
3 drops dish washing soap.
Fill the gallon bottle half full of water, add the additional ingredients, Shake Do not stir. Fill the rest of the bottle, shake again.................
With an old spray bottle total cost has to be under $0.50, the cheapest cleaner available.
