Wood furniture care - advice, product recommendations?

First a general question - wood is a natural material. Then typically it's coated in polyurethane, varnish, or similar that seals it? Wood care products talk of moisturizing the wood, etc. But it would have to get through that plastic / non porous coating? That doesn't seem to make sense. As I type this, there ARE stains that you can use on wood. And then not use poly or similar? That's the type of product that benefits from wood care products? The poly furniture? Just use glass plus or similar? You are cleaning / caring plastic at that point?

But the main question - we have wood furniture we bought for our daughter's bedroom 20+ years ago and moving it to HER house with her husband and baby on the way.

It's in good condition I think (we had glass panels made for the dresser and desk tops to protect them).

I'd like to give them a good cleaning / treatment while I can get inside & around all the parts.

What would you do? What wouldn't you do?

Lube the drawer slides with ______?

What product would you use on the stained surfaces? Leave it on a long time to soak in? Or just follow directions?

Do you put locktite (blue - semi permanent) on the knob threads? and / or on the bolts as you built the bed frame, etc.

There's dust built up on the insides - is wiping down the inside / bare wood with a water damp rag OK?

There's a couple shallow scratches down to bare wood. Is a matching color wood crayon is the best to cover it? Other ways to cover those?

And there's a few white scuffs from vaccuum cleaners? on legs. Anything you do for that? elbow grease and the wood care product?

THANKS!

 

7 question marks in the first paragraph. I'm afraid to read the whole manifesto.

 

Pledge for the exterior, maybe vacuum any dust, that is about all we have ever done.

Glass tops seem like an expensive item, maybe a desk/table but a dresser?

I've got pieces from when I was a kid, 55-60 years ago, still in good shape but way out of style, nobody would give much so I dont think I would go overboard.

 

@marq1 thanks! We got the glass tops when we got the furniture.

Yes! I can picture furniture my brothers had - it was blue color : ) Mine was a brown wood color, but not a style I'd care for now : ) And I don't think they were as high a quality as what we got for our daughter.
