My 3HP SawStop PCS is the pride and joy of the shop. It is about 3 months old, and has been treated with Boeshield once. However, recently I noticed some slight stains, and figured I should tackle them before they got worse.

I followed the SawStop manual and picked up some Scotch-Brite 7448 ultra fine abrasive pads. 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.

Am I being too picky? I realize this is a Saw, and not a show piece. Or, am I going about something wrong?

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.

I guess they shouldn’t have made it so pretty to start with :)

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)

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.

Bondo, that’s the best suggestion so far, and I don’t think it can be beat…............... Jerry (in Tucson)
