Acoustic guitars have specific care requirements that differ from electric guitars in a few important ways. The larger body, the unfinished or lightly finished soundboard on some models, and the greater sensitivity to humidity all mean that product choice matters more than it might on a solid-body electric.
Here’s a complete guide to the best care products for acoustic guitars — and what to avoid.
The Acoustic Guitar’s Unique Needs
Humidity sensitivity: Acoustic guitars are more vulnerable to humidity changes than electrics. The large, thin-walled body is designed to resonate — which means it’s also more susceptible to swelling, cracking, and glue joint failure when humidity is wrong. A case humidifier is essential for any acoustic guitar owner.
Finish variety: Acoustic guitars come in a wider range of finishes than electrics — from high-gloss poly on budget instruments to thin nitro on high-end models to completely unfinished or oil-finished tops on some boutique guitars. Knowing your finish type is essential before applying any product.
The soundboard: The top of an acoustic guitar (the soundboard) is the most acoustically sensitive part of the instrument. Avoid applying heavy products to the soundboard — a light wipe with a clean cloth is usually all it needs.
Products for the Body
For gloss-finished acoustics:
A microcrystalline wax applied every few months protects the finish and restores lustre. LORE® Microcrystalline Wax is safe on all gloss finishes and contains no solvents or silicone that could damage a nitro finish.
For light cleaning between wax applications, LORE® Instrument Polish removes fingerprints, sweat staining, and light marks without affecting the finish.
For satin-finished acoustics:
Use products sparingly on satin finishes — heavy application of wax or polish can alter the sheen. A clean microfibre cloth for routine cleaning is usually sufficient.
For unfinished or oil-finished tops:
Some boutique acoustic guitars have completely unfinished or oil-finished soundboards. These need very careful treatment — consult us or the manufacturer before applying any product to an unfinished top.
Products for the Neck
The neck of an acoustic guitar is typically finished in the same material as the body. Apply the same wax or polish as you use on the body, paying particular attention to the back of the neck where sweat and skin oils accumulate.
LORE® Fingerboard & Body Wax is particularly effective on lacquered necks that have become tacky — it restores a smooth, fresh feel without leaving a greasy residue.
Products for the Fingerboard
Most acoustic guitars have unfinished rosewood or ebony fingerboards that benefit from regular oiling.
LORE® Cold Pressed Lemon Seed Fingerboard Oil is the ideal choice — petroleum-free, naturally high in oxalic acid for stain removal, and rich in fatty acids that nourish the timber and help regulate moisture. Apply every few months, or whenever the fingerboard looks dry.
What to Avoid on Acoustic Guitars
- Silicone-based polishes — can penetrate the finish and affect the acoustic properties of the soundboard over time
- Petroleum-based oils — coat the surface without nourishing the wood
- Excessive moisture — never use wet cloths on an acoustic guitar; always use a slightly damp cloth at most
- Products not specified as safe for your finish type — particularly important on nitro-finished acoustics
A Simple Acoustic Care Routine
After every session: Wipe down strings, neck, and body with a clean microfibre cloth.
Monthly: Check humidity levels; refill case humidifier if needed.
Every 3 months: Apply fingerboard oil to the fingerboard; apply wax to body and neck.
Annually: Professional setup — check neck relief, action, saddle, and nut; inspect for any structural issues.
