A member at a club I used to belong with came up with this formula:

<span class=''msg''><font size=''2''>''Jim Quinn's Mix''

5 cups water
1 cup alcohol (91% isopropyl or stove alcohol)
1/2 cup ammonia
2 tsp detergent

I carry a little two ounce spray bottle in my flight box (a recycled CA accelerator bottle). I refill from a two liter plastic bottle. I have used this for more than a decade on gas and glow models with no ill effects. I use Parson's Sudsy Household Ammonia and Dawn detergent.</font></span>
