Cory Pre-Polish Piano Finish Cleaner is designed to be used prior to application of a piano polish. Deep clean and prepare your piano for optimal application of Cory Piano Polish. If your piano is dirty, with lots of wax and grime build up, you will want to clean it first with this pre-polish piano finish cleaner.

Cory Pre-Polish Finish Cleaner is the perfect choice for preparing your piano's finish for polishing. It quickly and easily removes wax build-up and grime. Pre-Polish Finish Cleaner is gentle and effective, and safe for laquor, polyester, polyeurethane or shellac finishes. Easy to use with the included fine mist sprayer.

If your piano is especially dirty, this is the product you want to use before you apply a polish to it. Deep clean the piano, removing the wax build up and finger prints. Once you have cleaned your piano's finish, it is now prepared for a beautified sheen using the appropriate polish for your finish (such as Cory High Gloss Piano Polish or Cory Satin Sheen Piano Polish).

Cory Pre-Polish Finish Cleaner is environmentally friendly, not toxic and safe to use as often as desired. Use on all your fine furniture.

Directions: Spray polish six to eight inches away from surface. Wipe dry and buff with cleaner cloth (non-abrasive cotton cloth). For cleaning the inside rim, lid or music desk, simply spray Pre-Polish on the cloth and wipe. Avoid spraying on strings or tuning pins.

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.

Should I clean my piano before applying polish?

Absolutely. Cory Pre-Polish is specially formulated to remove wax build-up, oils, and residue that can interfere with polish performance. Deep-cleaning your piano first ensures that polish adheres properly and delivers a consistent, even shine.

What does Cory Pre-Polish actually do?

Cory Pre-Polish is a deep-cleaning surface prep solution that lifts grime, fingerprints, and silicone residue from your piano’s finish. It’s an essential first step before polishing to avoid trapping dirt under a glossy layer.

Why use a separate product instead of just polishing?

Polishing without cleaning can trap oils, dust, and dirt under the surface—leading to streaks, dullness, or buildup over time. Using Cory Pre-Polish first gives your piano a cleaner, smoother foundation, which leads to a better end result.

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.

What’s the best product for cleaning a very dirty piano?

For heavily soiled pianos, Cory Pre-Polish Finish Cleaner is one of the best solutions. It’s specially formulated to break down grease, fingerprints, silicone buildup, and wax residue — giving your piano a clean base before polishing. Unlike water or household cleaners, it’s safe for fine wood finishes and won't harm satin or high-gloss surfaces.
