Never thought this would happen to my TS - SURFACE RUST IN AN HOUR

Cast iron can rust really quickly given the right circumstances, as you’ve discovered. I found out when I sweated on my saw. A good paste wax will slow the penetration of water but beyond that it really does nothing to prevent rust formation directly, and it doesn’t protect 100% from moisture as you’ve discovered. I like to use a light coat Boeshield T-9 rust preventer on my cast iron, buffed and dried, then add a coat of wax.

I buy a product called LPS-1 in 1 gallon or 5 gallon cans. Pour some into a spray bottle and spritz a light mist onto every tool in the shop every now & then.

Keeps the rust at bay, leaving behind a light film that prevents rust and wipes right off.

I feel your pain C_Plus. Like you, I worked hard for my tools and saved for them. I bought most of my tools with coffee $. Rather then spending $7 per day on breaks, I brown bagged my lunches and skipped my coffee breaks. I would pocket $35 per week for tools. My wife told me to just go out and buy the tools after being the sole $ earner while we raised our 4 sons, but I wanted to earn the tools. I dust them off after use and keep them sharp and polished. But I live in hot, humid South NH and my shop has 3 wall below ground level. It’s always sweating, but rust is at a minimum.

To deal with my situation, I remove the rust and put Butcher Block wax on the surfaces. The product I use to remove the rust is called “N Ver Dull. and comes as a wadding. I then cover it with butcher block paste or bowling alley paste. This combination works for me!
