Hi all -
I’m sure this must have been asked and answered before, and I apologize for (probably) repeating it, but I looked and didn’t find an answer, so here goes…
Last week, I made the mistake of leaving the barn/shop one night without covering the surface of my table saw, and since the weather here went from the 30s and dry that night to the 50s and raining the next day, condensation was a problem (which was compounded by someone else leaving the barn door partially open). I had waxed the saw when it was new a few weeks ago, but apparently not recently or heavily enough to protect the cast iron (note to self: SEVERAL COATS!!!).
Anyway, the cast iron table surface developed a light haze of rust (in a DAY!!!) I have used a very light duty (grey) Scotchbrite pad and some Liquid Wrench penetrating oil to remove the rust, which worked very well and I believe was as kind to the table itself as is possible while still getting the job done.
The Liquid Wrench was excellent at it’s job, and has no silicone in it, but it is designed to leave a light film behind it. I’m concerned that if I don’t get all of that film off, I’ll make a nasty mess when I reapply the wax. Can anyone suggest a solvent to remove the last vestiges of the Liquid Wrench, so as to leave a perfectly clean surface? Mineral spirits? Acetone? Rubbing alcohol?
While we’re at it, does anyone have a rust cleanser / penetrant they can recommend that won’t provide this problem?
Thanks again for any thoughts,
