Rust Prevention

1658 Views 9 Replies 10 Participants Last post by  greenacres2
I am moving to a new house and will be using a garage stall as shop space. We have cold winters here in Minnesota and tools tend to rust when temps go back and forth past the dew point. I thought of building a heated closet to store a cast iron table saw, bandsaw etc which are on wheels, along with portable power and hand tools. Thoughts?

G'day Scott, welcome to the forum.

Fortunately, that problem is not so bad here in Sydney....
Hi.Scott. A PTFE dry lube will help as well!
Down here in humid SW Louisiana I use Johnson's (floor) paste wax and have no problems. :)
If the closet is small enough you could get away with a couple of light bulbs mounted low down. Not the modern low energy ones, of course!
Hi Scott. Welcome to our little corner of the 'net.

As Bob(tvman44) stated, Johnson's paste wax works very well at inhibiting rust. Don't use regular car wax as it contains things that can ruin your project.

If it does get rusty, I use WD-40 and a Scotch-Brite pad to remove the surface rust, followed by a good application of Johnson's. Once it's clean, periodic re-applications of Johnson's will help prevent it from returning.

Hi, Brian.

I will try this on my heavy rusted handsaw
A fan running constantly seems to help a lot. I think it has something to do with stopping the water vapour from actually coalescing on a surface. Ie it evaporates as fast as it forms dew drops on cold surfaces, but that's with the light bulbs for a few degrees extra warmth. That keeps the relative humidity lower. (Temp drops= rise in relative humidity. )

This is universally practised here on boats (and RVs/trailers) in the Pacific Northwest.
Howdy Scott, I think I would try a couple of infra red heat lamps (the red ones) and a well house thermostat, and a heavy coat of Johnson's Paste Wax. If allowed to get to cold (below freezing point) your equipment will sweat badly as the temperatures rise or when you open the door. The IR heat lamps heat objects in the room and not the air.

I use Boeshield T-9. Works very well for me. Not only do we get temperature swings, but at 15 miles +/- from Lake Michigan...it gets a little humid at times.
