I built a desktop for a standing desk frame using a large pine sheet, and the stain is coming off on my hands and clothes.

I used some Briwax stain followed by about 4 coats of Danish oil. This was over 2 years ago and the stain is still bleeding out onto my hands or sometimes onto my clothes or legs from the underside of the desk.

I'd prefer not to go down the polyurethane path, so any other tips for sealing the desk so this doesn't happen.

So you know the solution, but don't want to use the solution?

Is polyurethane really the only solution as it doesn't provide the finish I want for the desk?

Eva888: Glass.

That doesn't help the underside of the desk, or do you mean a glass desk?

The softer oiled timber finish. I've used plenty of oil and water based PU in the past for shelves, but I don't like the hard finish it produces for a desk.

Sheet of glass on top but I guess that won’t help the underside. I’ve been looking at Shellac flakes but still researching it. You could try a wax instead of oil. People that use chalk paint on furniture use a wax coat afterwards so that might be a good type to try.

I would recommend waxing. Can take a lot of work and a few coats but it dries to a tough finish, sealing the wood.

That is pretty weird, both products should cure completely, I wonder if there is an issue with that batch of Danish oil, perhaps acting as a solvent to the stain? After you have sanded back, maybe stain it and wait a while, then test to check the staining step is OK before proceeding. I assume you used a rag rather than a brush to apply the Danish oil? Next time round you could polyurethane the bottom only for extra piece of mind.

Yes I used a rag for the stain and the oil. I might PU the underside anyway, but I need to fix the top at some point. Trying to find a time where I don't need to use it for a week to make sure it fully cures.

Are you sure your products are okay to mix? Might be brand specific, but all the Danish (and teak) oil I've ever used is penetrating. A wax undercoat will stop oil penetrating and it will just "dry" on top instead of penetrate and cure properly. Though appreciate you might be using another briwax product cf a wax wax. My instinct is that one or the other would be okay, but maybe not both together.

Large sheet of pine what? If it was a slab is it a resin pocket in the timber that's bleeding?

Danish Oil is polyurethane. It's just a mix of a cheap oil, usually boiled linseed oil (as opposed to something more expensive like Tung oil), and polyurethane.

(For the pedants, Danish Oil is just a generic term so it could be almost anything, but it's usually BLO + polyurethane).
