I've never used teak oil but I bet it's just as good as tru-oil, which is really just linseed oil that's been treated so it stays on the surface of the wood and form more of a shell (so I guess it's more of a linseed based varnish really). It's great for instruments.
I only got in to carnuba wax last fall when it was time to touch up the neck on a guitar I made about 5 years ago. I'd always heard that Music Man necks were just oil and wax but I didn't really trust it to be durable. But I actually found a half a tin of high quality wax that a neighbor put out with their recycling and figured why not give it a shot? It worked well on test pieces so I gave the guitar a couple new coats of oil and then waxed the whole thing about half a dozen times after that was cured and it's the best feeling finish I've ever touched. Can't recommend it enough! Just make sure not to get a wax that has silicon, it will work but it will also make it really hard or impossible to repair any damage later. I used this: https://www.amazon.com/Mothers-05550-California-Brazilian-Carnauba/dp/B0002U2V1O/
You just want to get one that's pure carnuba and you should be good. They use it on bowling alleys so it should last a long time and you can just add a bit more later on if you think it needs it.
No. That's a Cleaner Wax. You want the wax without the cleaner. It says Step 3 on the car and has a blue band on it. https://www.amazon.com/Mothers-05550-California-Brazilian-Carnauba/dp/B0002U2V1O/ref=asc_df_B0002U2V1O/?tag=hyprod-20&linkCode=df0&hvadid=312279483767&hvpos=1o5&hvnetw=g&hvrand=14297052339886462749&hvpone=&hvptwo=&h...
You really don't want to use the one with cleaners. Just get the Mothers with the blue splash on the screen. https://www.amazon.com/Mothers-05550-California-Brazilian-Carnauba/dp/B0002U2V1O/ref=sr_1_3?keywords=mother%27s+brazilian+carnauba+wax&qid=1670082320&sr=8-3 .
I buff/sand to 4000 grit and then wax without using any polishing compounds. I have used compounds, but I just don't see a difference. A lot of times after buffing with 4000, I'll drag out an old, used 4000 and go over it again with that.
You can try simply waxing the surface of the board and adding pads to the bottoms of the strikers.
I use Mother's pure carnauba wax (amazon), same as on my crokinole board. The maker of Muzzie's crokinole boards recommends Turtle Wax super hard shell paste wax instead (amazon).
Under the strikers I put teflon stickers (amazon). Other people seem to have good results with Scotch felt pads instead (amazon).
I did this to a new-ish board with two coats of wax and the striker movement was so slick, the game was difficult to play until the surface got some wear. The results won't be so dramatic with a well-worn board, but it goes to show that a bit of waxing will make a difference.
This is the exact wax I use:

You just want to make sure and get pure carnauba wax. Nothing with cleaners or abrasive elements in it.
You should use some pure carnauba wax on the boards. Most people recommend Mothers. https://www.amazon.com/Mothers-05550-California-Brazilian-Carnauba/dp/B0002U2V1O/ref=sr_1_1?ie=UTF8&qid=1483199201&sr=8-1&keywords=mothers+pure+carnauba+wax
I got my board from Muzzies, and Murray suggested that I use https://www.amazon.com/Turtle-Wax-T-223-Super-Shell/dp/B000BPSVJ6. It's a blend, and he finds it works best on his surface.
