I have a fair-to-middlin' pernambuco bow, gave $200, so not high end, but not junk either. The frog frequently does not slide forward when relaxing the hair, unless I push on the screw. However, it is not too tight to slide in the slot, as if caused by weather or something. But it was really gunky under the base of the frog:--base looks like it's made of brass; when I removed the frog and wiped off the base and the wood, it's a little better but sure doesn't operate smoothly.

So, can I use something common to fix this? WD-40, 3-in-1? Veg oil? Graphite? I surely don't want to ruin the wood. Never had this problem before. Thanks

Candle wax, rub it on both the frog and stick wipe clean, should be good for a long time....

Candle wax is what I use too. First clean the surfaces well with mineral spirits or naphtha - no alcohol.

Of course, trees frogs require a different lubrication, I might suggest a liberal dose of axel grease...

Don't use any oils! They will ruin the wood and attract dirt. If they penetrate the wood of the stick they will weaken it. Although graphite is a good lubricant for a lot of things, I don't recommend it for the frog, as it can cause discoloration. 
 

If there's a lot of accumulation of gunk on the screw, eyelet, and underslide, they should be cleaned off before lubrication.

R.M.,
What do you suggest then?

Candle wax or soap are ok, although there are better wax products for the job. I have a couple that I use, one for the frog, one for the screw.

Good Lord, the tree frawgs.  It's near about snowing here today yet they're whistling and pestering us for the early show of spring last week.

The wax worked perfectly.  Actually, I used some of that 'Sno-Seal' that the yanks use (and, admittedly, I do too cause it works) on their shoes.

Thanks for the tips.  I knew it had to be something simple.

You might try backing the screw (nut portion) out 1/2 a turn. You should then check that the frog is not loose when you put back on the bow and put the hair tightening screw in.

Good advice above . Clean and lubricate. Mineral spirits / naptha / lighter fluid for the wick type lighter is the cleaner of choice. Candle wax or bees wax on the wood and a light oil or silicone lubricant on the screw. Wipe the screw with a rag or paper towel too much lubricant is as bad as not enough. There may be an alignmentt issue or damage to the screw and the eyelet .... usually though it is a question of rosin / crud buildup.
