Default Carb cleaning: boiling lemon juice vs. chem dip

Anyone have first hand experience boiling a carburetor in lemon juice to get it cleaned? I've read it's as effective or more than those harsh chemical dips.

Can I clean my carb thoroughly and save the planet at the same time, or is this too good to be true?

The lemon juice is highly acidic... and can eat away at the aluminum. When you're dealing with carb, where tiny, tiny changes can affect tuning... is it worth it?

Stick with carb cleaner.

Don't boil in lemon juice I've heard soaking in lysol works pretty well. But the best is of course carb cleaner, it's made for just that job.

Yup.

But that brass is seated/threaded, pressed into aluminum. All the flat mating surfaces are aluminum, your pilot screw and passges? All aluminum.

Your call.

Lemon juice ain't made for cleaning carbs.
Industrial carb cleaners are made for cleaning carbs.

Lemon juice is perfectly fine for cleaning carbs if you are sensible about it.

The EPA over the last several years has been cracking down on
harsh chemicals like carburetor and parts tank cleaners.
With this crack down, almost all parts tank cleaners are a citrus based
cleaner that is comprised of orange and lemon juice.

While not as effective as the good old carb cleaner, it will work and it
wont' hurt anything. Obviously, don't throw it in and leave it sit
for weeks on end, but an over-night soak won't hurt a thing.

If you use it, I would suggest afterwards, washing it down with a good
base of some sort to make sure all cleaning (acidic) action has stopped.

And to add to what litnin said, run the lemon juice through two coffee filters first. You don't want any of the pulp stuff to get stuck in the passages.
