Finished up a hand-plane a couple days ago, costed it in Danish oil, and followed the typical steps. Soaked it, let it sit, wiped it clean. Soaked it again, wiped it again, and then dry for 72 hours. Looked at it yesterday and my previously buttery smooth surface “wept” I now have small drops of oil hardened on the surface. What’s the best way to clean these up?

My first instinct is to hit it with some steel wool, then apply another coat of finish, but I’m worried the droplets will just come back in a day or two and I’d really like to be done so I can wrap this gift up. Any other suggestions?

I’ll post some pics when I get home today

When this happens to me, I hit it with #0000 wool. As to the next coat causing the same problem, it probably will, just much less.

The pores catch the oil and temperature changes cause the oil to either suck in or push out. Unless the pores are sealed (by letting the oil throughly dry), it will keep happening.

To end the cycle, I’d just hit it with the wool, then buff it good with a cloth to get any scratches out.

Copy that, I assumed as much. We’re getting something like 50 degrees of temp change every day, so it’s not an entirely ideal situation. I’ll do that and hopefully it’s cured enough to wrap by Sunday afternoon.

You said your getting wide temp changes. Can you bring it into the house so it is in a stable environment and can cure?

I’ve often used a rag with Danish oil on it and rubbed the daylights out of the weeps till they disappear.

That was my technique when I first tried DO on red oak. OY! 8^)

Get it inside and warm. Danish oil is very slow curing in best conditions and may never cure in the cold. Rub out the nubs and keep wiping it dry until the weeping stops. If you need to top coat after rubbing out the nubs make it a very light one.

Maxyedor,

I discovered the same problem when using Danish oil; it weeps for several days after initial application even without temperature swings. I solved this problem by wiping the project two or three times a days for several days after the initial application. The spots of Danish oil that came to the surface were still wet and wiped away with no extraordinary effort. If I recall correctly, the weeping stopped after about three or four days.

What is considered soaking…..I finish small odd shaped parts by putting them in a Ziploc bag and gently shaking it a little, pull out of bag, wipe off and let dry. Is there some advantage of a long soak?

If needed, I will let it dry and then recount the same way.

Got it sorted out, rubbed it with steel wool, re-applied a very very thin coat 3 times and it’s good to go. The droplets weren’t hardened, but they definitely couldn’t be wiped away, it took the steel wool to scuff them off.

Believe it or not the house has been swinging in temp more than the garage.
