ethanol deposit remover

I have several small engines with carb problems due to internal corrosion problems due to running E 10 ethanol blends. I was in a gas station today and noticed that STP Is now selling a fuel system cleaner that states "removes deposits caused by ethanol". (This product comes in a green container and sells for 6.99). I know that the
ultimate solution is to replace or rebuild the carbs involved, but if there is any snake oil that would remove the deposits I would dsfinitely buy several bottles. Has anyone had any success cleaning out ethanol clogged carbs with any fuel additive?
 
I never had an ethanol plugged carb. I had some bad plastic fuel lines on yard equipment go soft, but the only deposits I have had were removed by ethanol. Jim
 
Try this: Take a couple of small dishes. In dish "A", pour a small amount of gasoline. In dish "B" pour the same amount of denatured alcohol. Come back a day or two later and see which dish is clean and which has residue. Then decide for yourself if you really need to worry about "ethanol deposits".

more realistic test would utilize a mix of water, ethanol, and gasoline. The "residue" is the gel resulting from water+ethanol.
 
Ethanol cleans out the crap deposited by the regular gas you"ve been using, but sure, blame ethanol! bass ackwards!
 
Water evaporates. If it's pure, it leaves no deposit.

Ethanol evaporates, and if it's only mixed with water, it leaves no deposit.

Gasoline is a mixture of dozens of compounds, some of which evaporate, and some of which do not. Those that do not will leave deposits in fuel system components when the volatile compounds evaporate.

Now it is true that ethanol attracts water, and water in fuel systems leads to corrosion, which can gum things up. But that's not an "ethanol deposit", it's corrosion.

It's also true that ethanol can soften up rubber components in fuel systems and gunk things up. But the gunk is not an ethanol deposit, either, it's decomposed rubber.
 
Snake oil.

In all the testing I have done over the last 20 years, if you want to clean the deposits run E85. Never ever heard of ethanol causing deposits.

I find if I have crap in my carb its because my gas tank isn't clean (which is common on old tractors). Ethanol in the gas ain't teh culprit.
 
Ethanol "deposits" and a badly rotted carb caused by letting gas (ethanol or not) rot and go "bad" over several years is quite another matter!
 
Mark,

Thanks for your reply. It would be more accurate to refer to ethanol corrosion deposits. Since ethanol is acidic and hygroscopic, and increases electrical conductivity of the fuel blend, and carburetors are made from aluminum/zinc alloys, use of ethanol/gas blends used in small engine fuel systems set up a highly corrosive environment in the carb. Oak Ridge labs has an excellent report documenting how corrosion and elastomeric softening happens in engines and fuel systems fueled with ethanol blends.

I am interested to know whether there is chemical approach to eliminate the typical white colored corrosion deposits inside small engine carbs due to use of ethanol/gas fuel blends.
 
So if I was running E85 in my, whatever, car, tractor, lawnmower, for years with no issues and then switch to pure gas and start having problem. Shall I start blaming the @$#!!*&$# gas?

If I change a light bulb in my kitchen ceiling light and the next week the switch goes bad. Shall I blame the new light bulb.

Seems there are alot of folks doing this with ethanol. Ethanol blends have been around since the 70's and you're just now having issues? Hmmmm
 
You do realize that ethanol is jusy moonshine with a little poison added. So if what you're saying is correct then Why do you drink moonshine?
