GuitarTek Guitar Polish Duo

GuitarTek Guitar Polish Duo

Bring back the shine. Restore the feel. The right way to care for your guitar.
Your guitar’s finish and fretboard take the brunt of years of playing. Fingerprints, sweat, smudges, and dry conditions slowly rob your instrument of the deep, “dipped in glass” shine and smooth feel that made it special in the first place.

And when your guitars are more than “just guitars,” taking care of them the right way matters.

The problem with most guitar care products
Most polishes and fretboard oils weren’t designed specifically for guitars. Many are adapted from other industries, loaded with silicone, petroleum, and harsh chemicals – ingredients that have no place on a fine musical instrument.

You end up just guessing about what’s safe and hoping everything works together.

The GuitarTek difference
The GuitarTek Guitar Polish Duo was built to do things differently. This carefully matched two-product system gives you everything you need to restore high-gloss finishes, rehydrate unfinished fretboards, and keep your guitar looking and feeling the way it should… clean, smooth, and properly maintained.

Gloss Max

Gloss Max restores a deep, mirror-like shine to high-gloss finishes without haze, buildup, or greasy residue. Designed specifically for guitars, it safely brings out the beauty of delicate finishes while leaving behind a clean, showroom-quality gloss. No silicone. No petroleum. No harsh chemicals.

Board Oil

Board Oil uses real Amazonian Rosewood oil to rehydrate unfinished fretboards and restore the rich, smooth feel unfinished wood loses over time. Its innovative applicator delivers the right amount of oil exactly where you need it… no pooling, no waste, and no over-saturating the board. The result is a fretboard that feels fast, smooth, conditioned, and alive again.

Designed to work together
Because this is a complete system, both products were designed to complement one another… restoring shine where you want it, conditioning the wood where it matters, and helping your guitar feel balanced and cared for from top to bottom.

Just as important, we removed what didn’t belong. No silicone. No petroleum. No harsh chemicals. Every product in the system is dermatologically tested, so it’s safe for YOU too.

How to use
Apply directly to a clean cloth and wipe onto the surface. Allow the polish to sit briefly before wiping. Flip the cloth over and buff with the dry side of the cloth to reveal your guitar’s full natural luster.

What players are saying

“Gloss Max made one of my older nitro finishes look incredible… deep shine, no haze, no greasy feel afterward. It honestly looked better than I expected.”

“Board Oil is the sleeper hit in this set. The applicator is genius. No mess, no puddling, and the fretboard felt noticeably smoother almost immediately.”

“The biggest surprise for me was how clean everything felt afterward. No gummy residue, no weird slickness… just a guitar that looked and felt right again.”

“You can tell this was made by people who actually work on guitars. Every little detail feels thought through.”
