No, vodka (at 40% alcohol) has too much water in it. Everclear (75%) may work and everclear @ 95% will work the best. It still won't light as easily as Zippo fluid but it'll work; if not, let your zippo dry out and you'll be all set to try something else.
Yes, but it won't light unless it's over 100 proof, and even then, the flame wouldn't be very stable.
No. Zippo fluid is made out of naphtha, which they sell at hardware stores.
Sure
I have used the gel from a can of Sterno. Just smear blobs intermittently on your pile of coals and light. It seems to burn cleaner and is not as "explosive" as lighter fluid.
No you can't. H2O2 is not flammable, it is an oxidizer.
preferably you should use official zippo light fluid but another you can use is basic lighter fluid.
I do not believe so. The reason why you can only use lighter fluid is because it does not burn very hot. There may be a substitute, but I do not know of any.
There is no substitute available that can be used for brake fluid. Using anything other than brake fluid could be dangerous and would likely cause damage.
Lighter Fluid
you could be any age, you just have to be 18 to buy lighter fluid
Yes , as is Zippo lighter fluid .
any lighter fluid, except for bic lighter fluid
Naptha, from the paint dept of any hardware store. Lot more for the money and works fine. The Jon-e fluid and lighter fluid is naptha. I have been using it for years in Montana.
Slide the lighter body out of the lighter case, by pulling on the wick cage. With the lighter body upside down squirt lighter fluid into the fiber packing in the lighter until saturated. Reassemble the lighter body into the lighter case. Let excess lighter fluid evaporate before using the lighter.
