I recently picked up a small box of those tiny little alcohol prep pads and they are without a doubt one of the most useful cleaning tools I've used. You can get a box of 200 for like $5 and they're perfect for small cleaning tasks where you need to remove resin or whatever from tight places. To list a few, they're perfect for cleaning out a bowl in a jiffy, cleaning the threading on your grinder so it isn't so sticky, wiping down any stir rods or picks used to clear out bowls, or anything else that gets sticky and smelly! Do yourself a favor and pick some up, you wouldn't believe how useful they have been.
Super clutch since i always end up forgetting and my eyes get red as the devil's dick every time i smoke. not sure if this is common knowledge, but it was a lifesaver for me
