Pro tip: a $2 thrift store oil can saved my table saw from rusting in my garage
Last Tuesday I was cleaning out my garage in Boise and noticed a little rust spot starting on my cast iron table saw top. I grabbed an old oil can I picked up at a thrift store for $2 and gave the whole surface a thin coat after wiping it down with a rag. Three weeks went by and we had a bunch of rain, but when I checked it again the top was still smooth with zero new rust. I used to buy those spray cans of protectant for like $12 each and they never lasted. What's your go to for keeping cast iron tools rust free in a humid garage?
