Am I being too picky?

Yes. Even the most cared for cast iron will develop a patina over time.

I had a similar experience and boeshield It works to help things slide on the top, but I too noticed that.

I stripped it off. I used mineral spirits and a small piece of 1500 wet/dry paper wrapped around a small wooden block.

I took it and took the block in one direction front to back and overlapped by half the width, till I did the whole top. Took an hour or so and a good bit of mineral spirits. When all done, I put a couple good coats of johnson’s paste wax. Thats my go to finish now.

Well, I manned up and tackled the rest of the spots. The top no longer has that uniform sheen, but it is clean.

I just put a heavy coat of Boeshield down. I think I’ll let that sit over night, buff it out, then put a couple coats of Johson’s.

Bones, it sounds like you did the whole top. I probably should have gone that route. When I need to do it again, I might make it more uniform.

Correction, after reading about T9 getting gummy, I chickened out. I let it sit for about an hour, then wipped it off. We’ll see how that does.

T9 is just paraffin wax and mineral oil in mineral spirits… you can make your own pretty easily and for a fraction of the cost. If you don’t like the mineral oil, just dissolve some paraffin wax in MS, wipe on and let dry.

Cheers,
Brad

PS: JPW is just paraffin and carnauba wax in naptha… the common theme here is wax.

I had a similar problem from setting some green wood on my saw. It developed a few stains and some slight rust. After cleaning it I noticed other areas didn’t have that clean shine it use to have . I tried some brass and copper cleaner/polish and the results were astounding with only a soft rag.Made a 10 year old top look like new. I then gave it a coat of wax. Worth a try.

Yeah, same boat as OP.

For me, it boggles the mind that it isn’t just standard industry practice to plate the top with something that won’t rust.

After wasting a lot of time trying to recover/protect my top, I’ve just decided to not worry about it anymore. I have developed a firm and fast rule that nothing sits on the saw top. That yields other benefits, such as not having to clear it off to use it. I use boeshield and occasionally re-wax it.

Mostly I just stopped expecting it to delight me when I walk into the shop.

Don’t worry about it. It’s a tool, not a finished workpiece. Function is the important part of the equation for tools.

I am certain that the tops could be plated. The problem is will people be willing to pay a couple hundred dollars for the plating?

When it has sawdust on it, you will not notice any spots.

As others said, yes, you’re being too picky…but you’re not alone. What drives me nuts are the drips of sweat that end up on my table saw. I’ve just learned to live w/ them.

Yeah, Hobbyists. I don’t know why someone wants a tool in their possession that looks like it’s not ever been used. It’s a tool, and it’s supposed to do a job, not sit and look purdy.

It’s like people who own 4 wheel drive vehicles that are 5 years old without a single scratch on it. In reality, it’s probably never been used for it’s intended purpose…... Jerry (in Tucson)

I cleaned the top with mineral spirits, and then tackled a spot with WD40 and a Scotch-Brite. Although it cleaned up the stain, it appears to have discolored the cast iron top. It no longer has that sexy smooth shine, but you can obviously tell where I took the abbrasive to it.

Remove the top and set it on a hot fire and grill some bacon on it. You won’t be able to tell where that spot is.

Put a 150 grit disc on your ROS and sand it then toss the disc. Follow with wax and buff.

I think the only way to keep that saw pristine is to never use it. I wouldn’t let anyone touch it either, as fingerprints can make a permanent mark. Rope it off with velvet ropes to keep the riffraff away.

I have the same saw and I felt the same way. But at the end of the day it’s a tool. It’s a tool that sits in your garage/shop, not in your house. After all, despite how sexy the saw is, it is not a piece of furniture. It is happiest when it’s chewing through a 8/4 piece of oak.

In terms of rust prevention, I had some issues with the table top because my backyard is the Atlantic Ocean. The salt content in the air alone is enough to season your dinner plate.

I tried every regiment and the most successful has been the T9 and Renaissance wax. I apply T9 overnight and let it sit until it’s unbearably tacky. Take a lint free cloth and buff it afterwards. It’ll still be tacky, but less so. Then I apply 3-5 coats of the wax. Keep in mind this is the initial coating. For upkeep, I usually clean of dust and dirt and reapply 1-2 coat of wax every other week. It might be excessive, but I haven’t had rust on it yet. I think what’s happening here is the T9 prevents rust and the wax protects the T9 layer.

It took me a while to build up the layers, but not my table laughs at water. I still get nicks though, cast iron is surprisingly soft.

DBordello,
I have two brothers….one of them sets his beer on his iron tops…the other waxes his lawnmower after every use…that is why people are called “individuals”.

Ok, I don’t have any brothers and that was an exaggeration, but if it gives you pride to maintain your saw as pristine as possible, go for it….Personally, I have the same saw and it bothered me greatly to get that first scratch. I got over it, continue to use the boeshield, from my experience that stain will fade. Be very carefull of sanding, buffing, or scotchbriting…as mentioned, cast iron is softer than you think.
Just my .02
