Short alcohols are what chemists call Amphiphilic; they interact favourably with both polar and non-polar things.
So if you add a bunch of alcohol to your grease the alcohol starts mixing with it. It mixes with it all over (because it is amphiphilic), but one of the important ways it mixes is by getting in between the long fatty chains. This helps liquefy the grease because the long fatty chains packing together is what makes grease a solid; if you stick something small in between the long grease chains they effectively melt (similar to plasticizing agents in polymers).
So why not use ONLY alcohol? Because while alcohol interacts favourably with all of the grease, it can’t actually dissolve much of it on a weight of grease per volume alcohol basis. You can dissolve (note this is not the correct technical term, but is serviceable for us) much, much more fat into water with soap. From Reddit
you can buy pure Ethanol from eBay. This is 95% alcohol. Do not drink it. Keep it out of the way of children ( which includes daft teenagers). It must be used carefully. Then there is the issue of packaging. It will probably come in a plastic bottle and plastic packaging.
Then you have to consider the additives. Denatured, or industrial, alcohol is ethanol mixed with unpleasant additives making it undrinkable. Obviously you cannot use this to make essences flavourings and tinctures.
The other option is to buy the highest proof booze you can find.
