Nope... I use a mix denatured and simple green myself... used it for YEARS... most of those planes are still flying after ten or more years.

Seems to take off everything except the monokote. Can't think of the name right now, but it's sorta generic sounding.

"Fuel for alcohol burning appliances" and "Flammable liquid". I wouldn't spray glow engine fuel on the surface of my plane either and think it was safe.

understandable, I would only do it if the engine was totally cooled and powered off. I was more concerned if the alcohol would deteriorate or discolor the coverings or penetrate the wood in a negative way.

i think the concern was for a fire breaking out when sprayed all over the plane...

Obviously one should observe similar precautions with alcohol as with any other flamible solvent such as paint thinner, laquer thinner, MEK, acetone, etc. In the presence of a modicum of common sense use of denatured alcohol poses little undue risk.

Status: offline 		I use denatured alcohol all the time, at the field, in the shop, no problems. It evaporates rather quickly. I keep a spray bottle in the shop and use it as a hand cleaner, or spray it on a rag, use it to thin or clean up epoxy. I wouldn't recommend smoking while using it, and if you soak a rag, spread it out to allow the alcohol to evaporate when done, but it's a lot safer than gasoline.
I buy the cheap version of "orange cleaner" or Windex at the dollar store and cut it 1:1 with denatured alcohol to use as a plane cleaner, no problem with any painted finishes, fabric or plastic covering.

Your glow two-stroke engine throws unburnt methanol all over your model while running. One of the reasons that these engines are on the EPA's s**t list is because two-strokes are sloppy and inefficient.

The idea of using it all the time kind of bothers me from the "breathing it" standpoint. Also using it for hand cleaner means that some of it is getting into your system through the skin. These things are hard on the liver. Maybe I just worry too much!

Thanks,

Ernie

Status: online 		Again, denatured alocohol mixed with windex works awesome at cleaning glow fuel residue off of a plane. What do you think is the major ingredient in windsheild washer fluid is (menthanol). Is that not the same as the major ingredient in our fuel.
Maybe some of you should take a chemistry class once in a while.
You remove ca from covering with acetone, that is a hell of alot tougher chemical than alocohol, and it does not hurt the covering.

Status: offline 		Chemically yes, precatically no. As they both have different boiling points, they could be distilled but it would be beyond most people's means. Same as cracking petroleum. Every volitile has it's own boiling point and cracks out at different temperatures. It would be a whole lot easier going down to the local package store or chemical warehouse and buying pure ethanol. Or a bottle of Chivas.
