I have a fairly new (2 years old with little use) Milwaukee M12 1/4 cordless impact driver, was using it this morning. It was sunny outside, no sign of rain, so I left it along with some other tools to make a quick run to Walmart. When I got to Walmart it stared pouring, and my tools at home got soaked. I dried off the Milwaukee as best as I could and it still works fine, but should I spray it with some electric cleaner? First time this has happened and I hope I dont have to buy another one as I bought this one on sale.
