The grand piano sweeper is designed to dust the hard to reach soundboard of your piano. Dirt and dust on your soundboard can impact the sound quality, and start to ruin the varnish on the soundboard. This tool allows you to quickly sweep the soundboard, including underneath the iron frame by inserting it into the holes, and is long enough to clean under the treble strings (bass strings). If the piano is particularly dirty, you can dampen the sock to help with cleaning.

Made of flexible plastic that is covered by a cloth sock for cleaning. 50" long x 1" wide. Sock is removable and machine washable and will not scratch the soundboard. A very useful and popular piano tool.

Frequently Asked Questions

What is the best piano polish and cleaning brand?

Cory is the most trusted and used brand in piano care. Their products are specifically formulated for piano finishes, including high-gloss, satin, and wood tones. Trusted by technicians and musicians worldwide, Cory cleaners and polishes are gentle, effective, and safe for use on fine instruments.

How do you clean under the strings of a grand piano?

Cleaning under grand piano strings is tricky without the right tool. The Grand Piano Soundboard Duster is designed with a long, flexible handle and soft fabric to slide under the strings and remove dust safely—no need to dismantle anything or risk damaging your instrument.

Why is it important to clean the soundboard of a grand piano?

Dust buildup on the soundboard can muffle sound and degrade tonal quality. Over time, it can also attract moisture and pests. Using a purpose-built soundboard cleaner helps maintain sound clarity and prolong the life of your piano.

How often should I clean my grand piano’s soundboard?

For most homes, cleaning the soundboard every 3–6 months is ideal to prevent dust buildup that can affect sound quality. If your piano is near open windows, used frequently, or in a dusty environment, monthly cleaning may be better. Using a dedicated soundboard duster ensures safe and easy maintenance.

Can I use furniture polish or household cleaners on a piano?

No. Regular furniture polish and household cleaners can damage piano finishes by leaving streaks, wax buildup, or even removing protective coatings. It’s important to use specialized piano cleaning products designed to protect delicate finishes and materials.

How often should I clean and polish my piano?

For most home pianos, a light dusting once a week and polish every 1–2 months is ideal. In schools or performance venues, where use is heavier, monthly cleaning with a professional-grade product like Cory polish helps maintain appearance and finish integrity.

Why is this the best soundboard duster for grand pianos?

Unlike shorter dusters that only reach the front portion of the soundboard, this tool is extra long—designed to reach the full width of even large concert grand pianos. It’s the only duster on the market that can safely reach the center of the soundboard without disassembling your piano or removing strings.
