I'm a pharmacist and I'm finding this thread interesting. I've got a doctor of pharmacy degree, and work retail pharmacy. I also was a chemist and drug compounder for a pharmaceutical company before I went to pharmacy school. My wife is an Internal medicine physician. So this is like my normal table talk.
In retail I am often confronted with all sorts of minor cuts, blisters, and scrapes at the pharmacy counter. So I end up being a triage station. Of course the minor things I just help them out with, anything I feel is infected or too deep I either send to ER or their doctors. The people come to the pharmacy cause my opinion and advice is free, and most people aren't sure what to do. I agree with Doctor Averageiowaguy. I usually give them the same advice. If they have tried triple antibiotic before, then I will usually tell them it's fine for minor cut and abrasions. I've also had doctors send patients to the pharmacy to buy it as well. I also usually tell them to keep it clean and covered if it is in a place that can easily get dirty. If it isn't in an area where it will get rubbed or dirty, and not bleeding, I tell them to just leave it uncovered. Again this is MINOR scrapes and cuts. I also frequently get people with friction and heat blisters in as well. Large scrapes and some burns I've seen doctors send them in for occlusive, or semi occlusive bandages to keep the area moist. But don't quote me on that cause its definitely beyond my area of expertise.
I usually have mercurochrome (monkeys blood) around for the old timers that come in. My grandmother put that stuff on me for just about anything. Bactroban (mupirocin) is pretty awesome because it has good staph and strep coverage, but that's a prescription drug.
The menthol shaving cream in DoctaD's uncles home remedy is not a bad idea. Most shaving cream has plenty of emollients, moisturizers, and cleansers in them. The thickness of the shaving cream would be pretty good to help spread it around. Plus it would smell good.

I've compounded creams with some of the same ingredients.
I have some shaving cream around here that has aloe in it too. That would be great as long as you weren't allergic to it. As far as what to carry in a PSK, I carry around a small container of Vaseline, various sized bandages, and some alcohol swabs. The Vaseline, bandages, and alcohol swabs have multiple uses. I'm sure you could see fire starting potential with all three.
One thing I would add is to make sure your tetanus vaccine is current. Tetanus vaccine is usually given every 10 years.
Thanks for all the input, this has been pretty informative. Averageiowaguy, I'm going to try to catch your podcast. I would definitely love to get some wilderness first aid CE. I'm going to look into that. Might be a tad bit more interesting that going to drug rep dinners.
