Steinway Furniture Care Products are ideal for your Steinway Piano Finish, as well as your other fine furniture.

As with all finishes, the surface has to be clean to be conditioned. Cory Products are special water base formulas designed for safe use on all high polish finishes. This means that any oil base polishes or cleaners that have been previously applied to the surface need to be removed before polish application. The following tips apply regardless of the material the gloss is made of......polyester, lacquer, urethane, etc.

For most circumstances, use Cory Key-Brite Key Cleaner or Steinway Furniture Care Cleanse and condition to prep and clean the surface. For heavy build up of waxes and oils, use Cory Coconut Wood Cleaner.

To remove fine surface scratches and deep clean older finishes, buff the finish with Cory Buff-Brite rubbing compound.

Test polish on inconspicuous area to check for polish compatibility!
Lightly spray Cory Super High-Gloss Polish directly onto large surfaces or into polishing cloth for hard to reach areas. Follow the instruction for Steinway Furniture Care  Two to three pumps from 6-8 inches away is enough polish to do about half of a top on an average grand piano. Excessive polish will cause buildup and be time consuming to remove. Wipe dry and buff with a clean, dry, soft cloth. If the surface cleans and shines easily than proceed to complete the job with this process.

If the polish streaks and resists the cloth than an oil and/or dirt base is still present and it may be necessary to additionally clean the surface as described previously. AVOID SPRAYING ANYTHING ON OR NEAR THE STRINGS AND TUNING PINS ON PIANOS! Apply Cory Super High-Gloss Polish as often as desired for regular maintenance.

How do I maintain the satin/wood tone finish on my piano or furniture?

Wood finishing materials have evolved dramatically in the past fifty years. Originally finishing materials were made of varnish or rubbing oils until roughly the 1940’s. The next generation of materials used was lacquer. In the mid 70’s to early 80’s, finishes became environmentally driven to water base. This history can be used as a guideline to determine what finishing material was used and the suitable polish to be used.

If your piano or furniture is brand new or relatively new, your best choice to clean and maintain the surface would be Cory Satin Sheen or Steinway Furniture Care Supreme Polish. 

Pre-cleaning may be required for surfaces where oil-based polishes such as Pledge or similar lemon oils have been used. Use CORY Coconut Cleaner, Steinway Furniture Care Cleanse and Condition, or Key-Brite Key Cleaner to clean newer satin finishes. If deep cleaning of oil and wax is required on newer poly finishes, use Cory Buff-Brite. Test all products on small inconspicious area to assure finish compatibility.

Satin Sheen is a water-based cleaner and conditioner that has sheen enhancers. It is not designed to add shine or gloss to the finish; instead it cleans and conditions high-end satin finishes.

Spray Satin-Sheen 6-8 inches from finish. DO NOT SPRAY NEAR STRINGS OR TUNING PINS ON PIANOS. Wipe in the direction of the grain with a soft clean cloth. Cory Satin Sheen will not cause buildup and can be used as often as needed.

Some of the older satin ebony finishes have deteriorated too much for the Satin-Sheen to be effective. If your cleaning cloth is turning extremely black, this could be an indication that the clear coat has broken down leaving only a thin layer of color coat.

How do I repair water marks on pianos or furniture?

Here area few helpful steps for dealing with white rings commonly caused by wet glasses or spills on lacquer, shellac, or varnish finishes. Analyze Damage: The extent of damage can be estimated by analyzing the color of the rings. White Ring: Generally a temporary condition. If the finish is in good enough condition this mark can be removed without stripping. Yellow Ring: Indicates more serious damage resulting from prolonged water contact. These occur often on older, brittle, or deteriorated finishes. Although more difficult, some are repairable with simple measures as the moisture has not yet penetrated the wood itself. Black/Gray Rings: Occur when the moisture has penetrated through to the wood itself. Refinishing, bleaching, and sanding are usually needed here.

General rule of thumb is to use the gentlest means possible and progress from there.

   STEP ONE: Would be to do nothing. Many times a ring will repair and dry out itself, so give it ample time. Next, try putting the damaged piece in direct sunlight or use quick passes with an electric hair dryer to speed up the process.
   STEP TWO: Moisten a soft cotton cloth with mineral spirits or naphtha lightly wiping the area. If this has no affect try denatured alcohol next. Be sure to test on an inconspicuous place first as the alcohol will remove shellac.
   STEP THREE: If the stain persists, it’s time to try rubbing with mineral oil and rottenstone or baking soda as an abrasive. Be careful not to rub through the finish. If the spot disappears, you’ll probably need to rub the sheen back with 0000 steel wool and Cory Satin-Rub and re-wax the area to blend.
   STEP FOUR: If there’s still no progress you’ll probably have to strip. Mask off the undamaged areas at the joinery breaks and strip the finish just in the spotted area. Try to keep the stain or patina in tact if you can and avoid sanding as this will require staining. Care should be taken with antiques as the stain is often viewed as character defining or a true indication of age.

BEFORE YOU STRIP….
1) Be patient….the problem may resolve itself.
2) Try drying the spot in direct sunlight or with a blow dryer.
3) Still there? Wipe the blush spot with some solvent.
4) Didn’t work? Move on to rubbing out the finish.
5) Still see your spot? Strip the damaged section only.
6) Sorry, you are out of options. Strip the entire piece.
