Baking water off a chain is one thing...it's a unnecessary thing but it's one thing. Baking acetone off a chain is an entirely different totally unnecessary thing.

Acetone evaporates very quickly and a hair drier is unnecessary and, as has been pointed out, dangerous thing to do. It's not the bottle of acetone you have to worry about but you should worry about making a fuel/air mixture and then adding a spark to it. Just let it evaporate if you feel the need to chase water that you shouldn't have used in the first place off the chain. All traces of acetone will be gone in 5 to 10 minutes.

And do not put an acetone soaked chain in an oven of any kind...unless you want to rearrange your kitchen rapidly.

WD-40 is mostly Kerosene with about 10% thin oil similar to 3-in-1. This according to some friends who were in competition with WD40 (Kal-Gard). They had WD40 analyzed and that is what they found.

If this is true, then, a mixture of mineral spirits and bar-chain oil (90/10 ratio) would likely give even better results.

Part of WD40's cleaning effectiveness is due to its propellant: Propane (so I was told). Between the oily part of WD40 and the Propane, it'll clean and lightly lubricate most anything as propane is a pretty effective detergent.

I never mentioned baking acetone off in an oven. I seriously doubt if squirting acetone on a chain outdoors would cause enough of a concentration of fumes to ignite.

No, WD-40 isn't "mostly kerosene". The MSDS now lists the contents as flammable category 3 aliphatic hydrocarbon (45-50%), LVP (low vapor point) aliphatic hydrocarbon (12-18%) and mineral oil (25%). But older MSDS listings called the solvent "Stoddard solvent" which is mineral oil.

Also the propellant rapidly turns to gas...that's why and how it "propels" when it exits the aerosol bottle. It won't do much in terms of cleaning nor is propane any kind of detergent.

If the goal is to clean the chain, leave out the oil and just use mineral spirits.

Someone is bound to try it. As for igniting the fumes, it doesn't take much. Never underestimate peoples' ability to do something that will result in damage. That's why we have fire departments and why they get so much practice.

Thanks for the update ;o)

The Propane dissolves into the mixture and the combination does seem to have some detergent-like action, at least until the Propane is gone. I have reason for this opinion but the details are unimportant -- JM

Joe

BTW: When firemen give a demonstration of aerosol can flammability, they often use WD40; put a match in front of what comes of a WD40 can and one has a mini-flame thrower!

The propane is essentially converted to gas as soon as the nozzle is pressed. Small amounts can still be present in the mixture but it's not enough to have much effect.

Propane really isn't a "detergent". A detergent modifies the polarity of water so that water can be used to remove oils. Propane is very closely related to mineral spirits. It's not modifying the polarity of the solvent but is just another component.
