Rust Prevention

What would someone need to do to protect against rust on say a table saw top? Is wax sufficient? How often would the saw need to be treated? I would guess climate can effect how often the top gets treated.

When you find something that works let me know. I have tried everything you read about online that is supposed to work “better than anything else”

This includes Johnson  paste wax, Boshield and even Lie Nielsen Jojoba oil.  My table saw is next to my utility sink so I often splash it after washing my hands.

One of the guys on here mentioned clear poly but I have not tried that yet.

Boshield worked the best so far. 

Spray it on, let it soak a few hours, and wipe it off. Do that about every 3-4 months.

all my cast or surfaced ground steel is protected with raw straight up bees wax rubbed in but then again my shop is a constant 72 degrees year round so I’m sure that helps 

WD 40 every month or so and wipe off after that’s what I do with the tops on two sawstops two bandsaws 3 jointers and misc works great ?

About 3 or 4x’s a year I alternate between Boeshield and Johnson’s paste wax..

i do have the Lie Nielsen oil.. never tried that.  I may try it next time.

I have a secret recipe treatment, wanna buy some?! Lol

It’s a can of stuff I can’t even remember what it’s called, some old old waxy something, now I gotta go look and see what it is..I only tried it once a month ago after I removed a light bit of rust with a worn out sander pad on my ROS on the bandsaw, scroll saw and table saw… Something that has been in my in laws shop since before I was born probably lol

biggest rule in my shop is NO I repeat NO hot coffee cups on or near cast iron of any kind…..you want a ring in cast iron that will take you 3 months of sundays to get rid of go ahead it will leave a ring 99% of the time in a matter of minutes

Shouldn’t be too hard considering I’ve never had coffee before. haha

I like Ballistol or Boeshield T9. I follow up with Renassaince wax. So far so good though I had a complete moron moment and left a piece of PT on my Sawstop. Rust! After having a crying episode followed by the whole range of emotions, I sanded with steel wool and denatured mineral spirits followed by the above. Clean and no problems since.

@ChrisK PT?

Probably pressure treated. I had to think about it too.

But with Chris it might be Pizza Toppings.

No dude, pressure treated lumber. It’s treated to prevent rot but it is almost always wet when you buy it at the home center. Like an IDIOT, I laid a piece over my table saw over night. Came down stairs and there was a vertices line where the lumber was resting.

I sometimes use a piece of PT cut in the neighborhood of 6″x8″( exact numbers are not important) to hold my pizza .

??????? YUM !!

I knew that………another thing that will leave marks on a cast table top is a hot coffee cup……probably already said that but I’ll say it again…

Yup. Nothing damp touches my iron. Except for PT wood apparently.

Mineral Spirits

I used denatured mineral spirits and steel wool but in all fairness the spirits won’t rust your top. It eats the rust right up. Water, coffee, beer, humidity etc etc etc…..that’s another story. Of pure pizza toppings would rust it too.

Oh I said Mineral Spririts cause it is Damp haha

I happen to be in climate controlled basement, humidity hot cold everything is controlled so I don’t have much of a problem with my cast other than hot coffee cups…..did I mention they can leave a mark in minutes anyway, my father on the other hand had his woodworking shop outside in the garage….back then he heated it with you guessed it a wood stove so temps were all over the place hot cold damp dry wet you name it BUT he didn’t have a problem with any cast either, and the reason is simple..he made plywood covers for his table saw and other rust problematic tools such as planes ect ect always stored them on plywood.

as for the table saw he lowered the blade at night and covered it and left it covered even the next day if he didn’t need it…..might help someone with rust problems and hot cover cups for that matter…hmm

My shop is in my garage, humidity here is typically 95% in the summer. Rust is quick…..gonna try what @JimboS1ice recommended 

Even a light wipe of regular wd-40 will help keep rust off of most metal surfaces

I tried this and it didn’t seem to keep up. I should be more diligent in my efforts….I will try the specialist

yea thats for routine maintainance, the specialist is more coated for that, 3 and 1 oil has a rust prevention oil too you can give a shot

EDIT: You got that shitty ocean air though don’t you…

Not so much the salty air, I’m a few miles (5) away, but the humidity is sick

That’s what’s nice about where i’m at in Ohio, far away from oceans… although whenever it rains heavy, there are quite a few bodies of water that stick around for awhile. It’s the Great Black Swamp trying to reclaim its territory..

I like Comp’s father’s idea, i too, have to deal with an unheated garage BUT last summer i popped in an old window shaker A/C and that really helped control the humidity.

It’s the temp swings in the winter that help attract moisture on cast iron and leaves a layer of rust oh boy..

so then i do this:

..

Now i’ve been taking preventative measures to not let this happen again…

temp fluctuations don’t help either but at least us in the middle of the country don’t have salty ocean air, thats much worse than what we get, devil air for metal

I really don’t know why table saw manufacturers especially high end cabinet saws don’t get their beds plated with industrial hard chrome, like on hydraulic cylinders not bumpers. (not the shiny nickle plating)  you could put a flash electroplate on it in seconds and it would most likely last 25+ years sliding wood across it. We used to flash plate hog heads and they lasted 10 times longer but seen 1000 time more abuse than any table saw would see in it’s life time. the hard chrome would not even be noticed as under 4 or 5 thousands of an inch it is transparent and a flash plate would be probably less than half a thou

then how could they make money off you buying a new table saw in 5 years?

ya I guess its all about the all mighty dollar

Ha. Beat me to it.

Do the type of capable makers that use quality table saws really replace them when the table gets rusted? 

I will say I almost bought a table saw with granite top to stop rust but could not give up using magswitch stuff.
