50 dollar compact workshop blower that I originally purchased to use as a fire bellows. It works well to dry off your pellets/slugs when layed out on a blue shop towel. It is gentle enough to not send pellets flying but blows away any remaining loose lead or debris. I also use it when applying lube to get a good coat but try not to pool any in recesses.
All around handy tool also. On its highest setting it’s got 3/4 the power of a cordless leaf blower in 1/3 of the size.
I wouldn’t think water spots would play a factor in accuracy but it at least rules it out. Haha
