Topic tags/keywords: cherry finishing maple

Last year, I bought a couple of small (think of serving snacks) cutting boards from a local HS wood shop teacher. I decided that they needed some minor sanding and then cleaning. I intended to send them to family and friend as Christmas gifts.

After I sanded them, and for some unknown reason, I then decided to reach for mineral spirits to clean them. I didn’t flood them with ms, just cleaned off the dust, etc.

When I was done, I realized that I made a stupid mistake. I had wanted to use mineral oil (which I had) instead. I chose not to distribute them at that time.

The boards have been in the workshop for a year now and I want to make presents of them this year. My question, are these food safe boards? I’ve been thinking that I would re-sand them, and then flood them with mineral oil, wipe them down, let them dry and then repeat one more time to be sure.

I’d appreciate any suggestions as to how I can “save” them as a gift to be use as intended – for cutting or serving food.

I wouldn’t worry about it in the least.

No worries…..The mineral spirits have had plenty of time to dry (if you wiped them down good like you said)...Mineral spirits evaporates pretty quick, so I’d say a year is more than enough time….Just do what you said, and you’ll be o.k. to give them as gifts…....!!

I used mineral spirits last night to clean Halloween makeup off my face. The stuff evaporates in a few hours and won’t leave anything behind. Honestly if they’ve been sitting in a shop for a year, I’d be more concerned about dust contaminating them, for example if you were sanding painted or finished items, the paint or varnish dust could settle on the cutting boards and get lodged in the pores of the wood.

Yep, the consensus in the other thread was not to have any concerns.

However, one issue begs a question. What sort of Halloween makeup requires mineral spirits for removal? Was a blowtorch involved at any point during the process? I have heard (just anecdotal stories, mind you) that you can readily remove any kind of makeup with a belt sander. Variable speed control helps quite a bit. I do not have any specific suggestions regarding what grit paper to use.

It was some colored grease pens, probably mineral oil based. Probably would have come off with soap and water but the mineral spirits worked instantly.

Harmful or not I would taste mineral spirits every time I used them but if it doesn’t bother you and your family then go ahead.

Yeh, it would akin to “huffing” solvent vapors to get high. The dermal absorption route should be much less and I would imagine the duration of the exposure was limited. Mentioning that so William can sleep tonight. I doubt that he did any damage. We will monitor his future posts just to be sure.

Remember the good old days when mechanics used to clean up auto parts in a bath of gasoline with their bare hands?

Have you ever used a “salad bowl finish” on a piece destined for food contact? General Finishes Salad Bowl Finish instructions say to thin it with mineral spirits if desired before applying. I am certain that the same solvents are in the can when you purchase it. Where do those mineral spirits go?
