Care of polyester finish

Openwood · Post by **Openwood** » 27 Sep 2006, 23:06

We have a new Yamaha C7 at work and despite using a high quality protective cover the polyester finish shows up lots of little 'scratches' in certain areas (they aren't very deep at all - more like patterns of faint lines). Can these be polished out with anything? Presumably this is a common cosmetic problem with polyester finishes? I see that Steinway produce an aerosol cleaner and cloth, but maybe it reduces any other brand of piano to a worthless heap of charred wood and twisted metal immediately upon contact?

Any advice gratefully received.

poly is a modern finish and does not like spray cans of polish. The best way is to use T-cut and water. It acts like liquid sandpaper and removes very light scratches. You can also get cutting compound from car suppliers which comes in many different grades. Light scratches are common and nothing to worry about. Just becareful not get thestuff on the vitals bits like strings!

Hi,
I have just received a set of Cory cloths and polishes for my high gloss piano from www.pianocoversonline.co.uk. Seems to work fine. . and quick delivery too. they also have a few more interesting "knick-knacks" on their site, and a good selection of piano stools. Happy polishing!

A dampened microfibre cloth does the job best with no chemicals or gunk. The best one is the E-Cloth. If the polyester gets heavily soiled then face it, you're just a mucky pup, but it can be cleaned with an alcohol based cleaner which evaporates easily (like the Yamaha Unicon polish that they used to supply free with every piano, but now costs a fortune even if you ask your dealer nicely for some).

Things like T-cut will do the job but you run the risk of hard to remove residues caking up between panels.

Many thanks for your responses. I had a look for e-cloths online - they make different cloths for different surfaces, do you know which one is best for the piano?

The bog-standard general purpose one!

Bog-standard it is then! Thanks
