Greetings,
I’m looking for basic advice regarding a suitable working finish for teak kitchen countertops. Countertops are fabricated from planks, with individual planks being 6″ to 12″ wide, normally 8/4 in thickness. West System epoxy. Some planks are vertical grain, some a mix of flat/vertical. Never had a problem with the finished tops curling/warping.
After the slab is sanded to final grit, I’ve seen mineral oil applied…several coats over several days…once in use, sometimes the top of the countertop will suffer from water spotting. Another coat of oil – mineral of butcher block oil – will renew the look of the finish.
What I’m looking for is a finish for a working countertop. Not a showroom kitchen. I’d prefer to not have a thick film-type finish that could be compromised by a simple ding from a dropped object or that will give a plasticky look to the teak. I’d prefer to have a penetrating-type finish that will prevent things like water spotting, that will have a nice matte/satin finish, and that can be renewed weekly/monthly/as required with a simple wipe-on product.
Prior to applying what is recommended, should the existing tops be wiped down with acetone or mineral spirits to strip away some of the existing mineral oil that has been applied? Should they be sanded back to bare wood?
Any advice would be appreciated.

I used teak oil made by Behlen's. It is for a desk type counter top in a kitchen and has held up well.

Watco Oil provides a nice finish for teak. I don't know about how it would work if food touches the counter top.
Mongo,
I think you will come to hate this counter top. If you don't, you have MUCH more tolerance than I. I've been there! Other than as an unused demonstration of workmanship, the surface will be impractical on just about every characteristic needed for a kitchen counter.
Anyway, I advise against any finish other than mineral oil. You are describing a very toxic situation using anything else and especially with the frequency that you anticipate refinishing that food-preparation nightmare of a work surface.
Good luck!

Mongo,
Mineral Oil blended with beeswax would probably give you what you want.

Thanks to all for the feedback.
First I think I'll have them try a few more applications of mineral oil. If that doesn't provide a better finish, then it'll be Kyle's recommendation of adding beeswax.
Kyle, do you have any specific recommendations regarding the oil/wax? Oil:wax ratio, warmed before application, treatment between coats, number of coats, buffing out, etc? Any details would be appreciated. Thanks.
If all else fails, then I'll likely have the finisher go with something like a Waterlox finish, which, while not a #1 choice, is eventually foodsafe and supposedly a bit more durable.
Ah...the pleasures of working with wood!<g>
Mongo,
Oil/wax mixtures are not at all critical. The Sam Maloof mixture is equal parts linseed and tung with shredded beeswax added to the consistency of heavy cream. The mixture is heated on an electric double boiler (outside) until the wax melts then allowed to cool. It's used cold and rubbed vigorously with rags.
There are several negatives to the Waterlox. 1. It is very expensive for nothing but a tung oil/varnish preparation. 2. Being a varnish, it will give a nice surface sheen as the film builds. But this film will be very thin, will be instantly broken with any use of the top and wil require constant reapplication. Stay with oil and wax.

Clear, concise, and articluate reply. I'm trying hard to stay away from a film finish, thanks for the encouragement.

Mineral oil doesn't dry, so I think you might have trouble getting anything to stick over it, and I doubt you'll be able to get it out of the wood. You might be stuck.
Test anything you consider using on scrap with the same amount of oil on it.
I had good luck with Behlen's salad Bowl finish on a couple of cutting boards I made for my wife years ago. It's some kind of wiping varnish, I guess -- goes on easy. I use the boards all the time and wash them in the sink, and they look great except for the knife marks......
In my youth, when they still allowed wooden work surfaces in commercial kitchens, wood surfaces never were finished. We'd just wash them down thoroughly and scrub them with salt. 'Course they didn't look too great..............
It's interesting that fairly recent tests have shown wooden cutting boards to be more sanitary than plastic ones. Seems most woods are naturally antimicrobial, while it's almost impossible to get all the organic matter out of the knife marks on the plastic boards.
