Hey guys,

I can’t seem to find any info on this. I’ve made a few cutting boards and have finished them all with mineral oil and beeswax. I’ve put quite a few generous coats on them and let them dry in between. However, almost every time i put something wet on the cutting board I get some sort of water mark/stain on it.

Now I sand the boards, spray them to raise the grain, sand again and do this 2-3 times. Then I add the finish.

Would I be better off soaking the entire board in mineral oil? I’ve seen some guys on YouTube do that. Do I not have enough oil on it?

Thanks in advance,
Mike

Never used beeswax on a board, just mineral oil, and I do soak it, in enough to form a puddle, then flip it periodically, try to make sure it’s always coated on both sides. If that should bring out any more grain once it’s out, I sand it again briefly with a fine grit, then rub it again with oil and it’s done. Haven’t been doing this for long, so I don’t know about longevity beyond 4 years, but so far they’ve held up nicely. As long as they are not left in a sink full of water. Never had an issue with stains. The first board I made (which I kept and we use all the time, and I won’t even post here because I didn’t know a lot of the rules yet) gets a BEATING from knives and chopping, and then gets scrubbed with detergent and water, and still looks pretty phenomenal. I’m waiting for it to break down so I can toss it and make a better one, but it keeps holding up.

After I allow the beard soak up as much mineral oil as it wants, I heat the board to about 120 degrees, melt the wax in mineral oil (2 parts oil to 1 part wax) and put it on the board. Melted wax mixed with oil makes a good sealer paste.

Bondo’s suggestion is the easiest.

Penetration is key, as others noted.

If you saturate your board with oil, it won’t shrink and split or crack, providing you maintain it. I flow mineral oil on and let is soak in, until gone, then slather more on. Wiping it off in the initial stages makes no sense, whatsoever. You want the oil in it, not on a rag and, eventually, in the trash.

After you’ve drowned it in mineral oil, then you can do you beeswax thing, but I don’t think it’s necessary. Just touch it up occasionally.

The more aggressive you are, with your finish, early on, the easier it will be to maintain and the less prone it will be to gaining or losing moisture.

My thanks to everyone for chiming in to Mike’s post. Just to show you how much of a novice I am, I will start off by saying I’ve had the same problem as Mike BUT I didn’t know it was a problem. I always thought it was SOP. Like Mike I’ve been using the mineral oil and beeswax mixture, globbing it on and then wiping it off.

However, the light came on when I read Kelly’s comment; “Wiping it off in the initial stages makes no sense, whatsoever. You want the oil in it, not on a rag and, eventually, in the trash.” It makes perfect sense and I wish I had thought of it on my own. Thanks Kelly.

I’m getting ready to glue up a cutting board I am doing from a charity auction. When it comes time for the finish I am taking Bondo’s and Kelly’s advice.

I use a 50/50 mix of mineral oil and beeswax. I heat it up in small crockpot made for dips. And put it on hot then let it dry over night and take a paper towel and wipe the excess off. Never had any problems with them I’m on a couple hundred boards done that way.

Is this stuff safe after it dries for food stuff?

This is the Safety Data Sheet on the Salad bowl finish

Yes, it is food safe. It is primarily mineral oil. It burns that’s why it’s considered hazardous.

Salad bowl finish is varnish and mineral spirits. Anymore almost any finish is food safe once it is fully cured.

If it were primarily mineral oil it would be listed in the SDS, it doesn’t even list mineral oil. Apparently you didn’t read the SDS in the link I provided.

Initially I though it (salad bowl finish) was a mislabeled product to get people to pay a high price for mineral oil so I looked it up to see what was in it. I didn’t find any mineral oil as I thought I would.

Yep, simply wiping varnish. Also “yep” on the last statement.

So it’s a wiping varnish. I alway heard not to put a film film finish on a cutting board.

So have I. Just another marketing gimmick by the finishing industry.

Mark S has a video on cutting boards where he dilutes SBF by 50% and then uses it. He said it is important not to build a film. Also he was applying it to end grain, so not sure if face grain would work the same. I use beeswax and mineral oil.
