  • 1.  Pledge built up

    Posted 10-12-2022 21:44
    Greetings all,

    a customer called me and wanted to know if there's anything that can be done to remove the build-up of pledge products that were used for many years to clean the piano. 
    It has left a milky/hazy residue.
    The piano is an Essex upright with a polyester finish.
    Thank you,
    Peter

    Behlen has a number of products that can be used for wax removal however I suggest you contact Allied to see what is best . Because it is an Essex it will probably be wise to talk to someone at S&S. Good idea to have a serial number and model as well as model year. Finish formulas change . Pledge is like WD40 it should be banned for use on pianos.  I had a customer with a Boston that tried to refinish the music desk because the finish wore of from contact with hand oils and perspiration. They tried to claim it was a warranty issue but I found evidence they tried a home made fix. My finish guy had to completely strip the music desk and refinish it. They cried all the way to the bank.

    the milky/haze may mean the pledge and rubbing got through the surface sort of like a water ring

    I'm curious, how does one strip a polyester finish?

    The Boston piano I mentioned had a satin finish that was not polyester however the owners husband attempted to sand down the problem are and tried using black paint making a big mess. To remove polyester for repair work like cracks and gouges you need to grind away the damaged area. Complete stripping of the finish is quite involved . Caliveri in New York does this for cases, lids, legs etc.

    I have to look at my notes on poly repair but I believe it is either naptha or acetone that can be used for cleaner . Getting pledge and waxy buildup off with mineral spirits looks like it works according to Paul  but I have not tried it. I did have some success using a Behlen dewaxer on a black hi gloss Yamaha lid. Some genius at a wedding reception in a local country club thought the lid was a great place to put a candlebra on. The drippings got all over the lid. Fortunately the maintenance crew didnt try scrapers or brillo pads

    I'm not aware of anything that will dissolve the finish.  I've heard of heating it with a gun and scraping it off, but never tried.  The normal off-the-shelf strippers won't remove it, though it might make it look dull.  Add some polish and it's good as new.  I'm all ears if someone can correct me.

    Turpentine should work.
    In California we have lost many of our solvents like paint thinner and naptha due to its polluting qualities.
    But we can still buy charcoal starter, which is similar enough to paint thinner and I have been using that as a useful solvent.
    Alcohol might work, but the risk to a shellac finish is too great, paint thinner or "charcoal starter" is probably safer (though smellier).
    You could also try just another application of Pledge as it might dissolve enough of the old residue to work as a cleaner.
    WD-40 might work too, or Goof-Off.
    You also might want to just try a simple cleaning agent (I use Spic n Span) and some elbow grease.

    We can't buy Alcohol in Califunny either-although we can still buy Shellac, but not the alcohol to thin it!!!! BTW, you can still buy it in Oregon. . . . . And that's all I'm going to say about that!!

    I believe most if not all charcoal lighter fluid is the same as mineral spirits. I don't use lighter fluid to start the charcoal grill anymore but I keep it on hand for other solvent uses.

    If you buy tar remover for cleaning your car, try charcoal lighter fluid, usually a lot cheaper.
