People ask me -
Lumpy, How do they make round toothpicks?

I don't know why they ask me that. But the answer is -
They use a toothpick making machine patented in 1872 by
Silas Noble and J.P. Cooley. So there's that answer.
While you're pondering the absurdity of that, consider this
How many people named "Silas" do you know?

People also ask me -
Lumpy, How do I clean, polish and take care of my guitar?

Well, if you're Willie Nelson or Keef Richards you don't.
But if you're like the rest of us, and prefer to keep the thing clean,
here's the stuff I use, combined into one kit that should
last literally for years.

CLEAN that instrument! Then PROTECT it! Then SHINE it!
And while you're there, keep the fingerboard HYDRATED.
DO NOT use Pledge or car wax or something with silicone. If you do
the silicone will make it VERY difficult for glue or lacquer to stick
to the instrument should it ever need repair or refinishing in the future.
Use something DESIGNED for MUSICAL INSTRUMENTS.

Whatever you use, don't use a lot. Use a tiny bit every now and then
not a lot all at once. Unless you routinely pour tequila all over your guitar
or do the Jimi Hendrix at Monterey imitation, you shouldn't have to polish it
more than maybe once a month.

Use the right combination of polish, wax, finish shine
in the right order.
Any instrument cleaner or polish is made of some combination of
solvents (water, naptha, very light oil) plus some kind of wax or oil
or other chemical designed to remain on the wood. To clean, polish and protect
efficiently, use the products in the proper order. In other words, don't just continue
to add more wax to the finish. We all know from the Pledge commercials that waxy build-up
will lead to global instability, tooth decay and ring around the collar.

Instead, use them in logical order. The first thing you should put on your instrument
should do the most cleaning. It should contain the most solvent and do the bulk of the
removing of dirt and grime. And it should also dissolve the previous applications of
polish/wax that you may have applied in the past. Dirt and gunk resides in that previously
applied micro-thin layer of polish/wax. When you come along next time and clean, you take
away the dirt with the old wax. Imagine June Cleaver in her house dress polishing her walnut
dining room table. We're doing essentially the same thing, just without the sensible pumps
and pearl earrings. Well, some of you might care to dress like June when polishing your
guitar. That's...um...up to you.

There are a lot of blends, formulas, and styles on the market.
Chances are they are all pretty close in composition. As long as they
DON'T contain SILICONE, they should all be safe for your instrument.
Where I find a difference is in the ease of application and how long the
protection seems to last. A really hard, cake carnuba wax, for example,
is REALLY tough to apply. But it lasts for a really long time. But it's so darn
hard to apply and buff off that you end up not doing it for all the work it
costs. And if you don't get it buffed off well, it leaves the finish gummy
which attracts dirt and airborne goopyness. And everyone knows how
disgusting airborne goopyness can be!

Here's a combination of all FOUR of the products that I like.
In order of use, they are named -

RESTORE - PROTECT - SHINE - HYDRATE
