I have a Dewalt cordless drill.

I was outside in my planter area doing some formwork and ran out of
fasteners. I stopped and drove to HD to get some more.

During that time it rained...more like poured...

I had the drill standing up on a step stool (smart huh?) The rain or wind
must have knocked it over, and it felt into the planter area. When I got
back it's all wet. I peeked into the housing and saw some sand got inside
the housing. I tried to shake some of it out, but because of the wetness
some sand stayed inside.

It still works...but I am wondering whether I have done big damage to it.

I hope I don't have to get a new cordless drill.
