I personally recommend against isopropanol (and peroxide). Soap and water, more water, more water, a little more soap, mechanical scrubbing if needed, and more water. The solution to pollution is dilution (at least in this case).
The superglue soaked bandaid thing is an interesting approach, except for the part where you try to peel the bandage off without opening the wound. I use medical cyanoacrylate when I have it (dermabond or skinstitch) and it does work a little better (and probably stings less), but I have used regular OTC superglue on many wounds at home. You can buy dermabond on amazon, but because it's medical, it's stupid expensive. Both really only work well on wounds where you can get the edges together cleanly (like knife wounds). You want most of the glue on the surface of the skin, spanning the wound, and as little as you can manage in the wound (it does hold the wound together there but it probably delays healing if there's too much of it). I don't see much advantage to soaking a bandage with glue as far as glue going into the wound, and the disadvantages of not being able to see the wound (to look for infection) and risking reopening it when you remove the bandaid are significant. Also, you can absolutely use regular superglue to reinforce a wound that was initially closed with tissue adhesive.
I should probably shut up now.
