Yes. One is 70% and other is 99%. But both will do the job.
Actually I once had a vegan make me some really good sausage that used raw unprocessed tobacco leaf. It was pretty freaking good actually. The fact they're a vegan just makes it all the more entertaining.You eat tobacco??
Not often. After each smoke, you should do rudimentary cleaning. Alcohol should be used maybe monthly or quarterly. Also, be careful with alcohol. It can possibly cause an issue with finish.How often should I use the alcohol? After each smoke once a week once a month? What I have been doing is running a couple pipe cleaners through (non-bristle then bristle) after each smoke.
Most of my pipes are estates. They all get a thorough clean with alcohol on arrival. After that it's a couple of pipecleaners through the stem and shank, then folded over cleaners for the bowl immediately after each smoke.How often should I use the alcohol?

If any of my pipes start smoking sour or funky, I'd give it a thorough hot water flush followed by an alcohol clean, but that rarely happens.
Ah, now you may be touching on quite a raw nerve for some of the members here ?How do you do a hot water flush?
Now that's some information I never would have guessed I would learn on a pipe forum! That's cool!As a biochemist, 70% is far better as aI disinfectant, as it disrupts cell walls and makes bacteria pop, 99% simply dehydrates them.

Quite a few posts on this subject in the Forums if you do a search.
Essentially you run hot water from a tap into the bowl (gently, rather than a gush) and allow the water to soften and flush out the gunk from the shaft. If the shaft has a lot of accumulated tar, I use a fine bristle brush to "scrape" out as much of the gunk as possible. Then scrunched up paper towels to "ream" out and dry the bowl.
And, you can drink it. It wasn't half bad with Diet Pepsi.On a more serious note, the best thing I've found is Everclear. Nothing scientific, just my subjective opinion.
Makes sense to me. I use 91% Iso or Everclear, since those are two I have around. And as far as alcohols are concerned, once they have evaporated, they're gone. At least that was always my understanding. And the toxic components of burning tobacco are probably of more concern than any of those solvents...I'm also a biochemist/molecular biologist, and have something to add too.
Where it concerns cleaning pipes, you are looking for the appropriate solvent to dissolve and remove the "gunk" in your pipe. This undesirable material fouling your pipe is a heterogenous mixture comprised of molecules of various sizes and physical properties. The key property we're interested in is solubility--how soluble these materials are in a given solvent.
My somewhat thorough approach is to sequentially clean a pipe with the four clean solvents that will evaporate absolutely without fouling your pipe themselves: water, methanol, ethanol, and isopropanol.
Using this assortment of solvents, sequentially, means that you will remove the breadth of pollutants in your pipe with solubilities ranging from "most polar" (e.g. water) to "most non-polar" (e.g. isopropanol).
We can't use completely non-polar hydrocarbon solvents like benzene, toluene, and others (such as complex mixtures like gasoline or kerosene) because they will bind to the briar matrix and not evaporate cleanly.
Finally, I do use a denature ethanol (Home Depot) to clean pipes. The most important thing to note is what the alcohol was denatured with. In this case, it's denatured with a little methanol to make it undrinkable (and change its tax category). Avoid any alcohols that are denatured with "bittering agents" such as Denatonium.
Again, methanol is poisonous to drink, but it (and isopropanol) evaporate cleanly very quickly.
As you apply the different alcohols you will notice a new "flush" of "gunk" being leeched out, representing the groups of tars and other materials that are more soluble in one alcohol versus another.
And yes, there are some types of filth in pipes that are very soluble in plain old water.

5% usually. I spray it everywhere, at home and at work (everyone does). What you want to avoid is working in an enclosed, poorly ventilated space with 100% methanol where fumes can accumulate, or avoid prolonged skin exposure to high-percentage methanol. Just like any other solvent, I suppose.I would be curious about how much Methanol is used to commercially de-nature Ethanol.Methanol - Wikipedia

Methanol is nasty stuff, I don't know specifics about how much is ok to use in a work environment but I would never risk using it indoors (not without a professional fume hood).
