What should I use to clean the case of my Yamaha C2? #2911351 11/12/19 08:23 PM

My Yamaha C2 is polished ebony -- isn't that a polyester finish? So, it should be fairly durable, but probably not indestructible, right?

My tuner said to use Windex and a soft cloth, but I'm thinking I've read here *not* to use Windex?? I don't want to scratch it, nor do I want to make it cloudy. I also don't want to buy some expensive fancy polish if it's not needed.

If Windex is really the thing to use, I already have some and can use that. But, is it the thing? Also, what do you recommend for the cloth? Somehow it seems like all our cleaning cloths these days are that microfiber kind, but I feel like a more traditional cotton rag would be better. Why do I not have any of those?? :P

I am embarrassed to say that I haven't cleaned the case since I got it, and the curved side of it needs to be cleaned. I noticed it when I first bought it, but the position it's in right now you don't notice it. So I kind of forgot about it. whome But the piano will be repositioned on Thursday (yay!) and the curved side will be much more noticeable.

TIA for any advice!

Two drops of Dawn (blue) in a spray bottle of water and a clean cotton cloth is all I use on my C3. Just enough bite to remove buildup and leave a shine. Microfiber scratches poly over time.
Windex is not good for poly finishes as it clouds and dulls the finish.
Good luck with your C2!

Really, and it doesn't need to be rinsed off? I guess that's a lot of water and not much Dawn though. (We use blue Dawn mixed with vinegar for a lot of household cleaning, but I won't use vinegar on the piano! !0-0!

See, I knew I didn't like those microfiber clothes!!

Good to know!!!

If anyone else has any other tips, please share. Now I gotta find the right kind of cloth.

I mix up a concoction of water, a few tablespoons of vinegar, and a small drop of Dawn dish soap in a spray bottle. I use it on the finish, and the key-tops. Also use it on my vehicle windshields/windows, inside and out. And, I use the micro-fiber cloth.

You can also buy the Windex now without ammonia, and with the vinegar. Guess they found out about my cleaning concoction... smile

Works great!

Good luck!

ShiroKuro, my first suggestion would be to ask the manufacturer. In fact, you may already have their answer among the papers you received during the sale. But, I'm pretty sure they won't mind telling you again.

My second suggestion comes from information my piano's manufacturer gave me, when I bought my piano. They said, "Clean the keys using a soft, clean cotton cloth, ever so slightly damp, with half a squirt of Windex aimed at the cloth--- never at the keyboard." Never use a cloth so damp that water runs off the surface and drains into the cracks between the keys--- ever.

You may notice that this advice was for the keys, not the case. BTW, although the keyboard does need to be cleaned occasionally because of oils, shed skin cells, dust that falls out of the air, etc there is no real need to overdo it. I find that once every 3 - 4 weeks is plenty. And also BTW, if you wash your hands before playing, the keys will stay cleaner longer and the touch will be more uniform. There's a big difference in the feel of naked skin on naked key, and naked skin on grubby or gummy keys (which does not look or feel any better than it sounds).

Now, as for the case. Special products? Darlene, who sold me my piano, is all in for cotton baby diapers, washed enough to be really soft. Every day of the world, she knocked the dust off every piano in the store--- there were quite a few; I'm going to guess, close to 100.

Now I absolutely believed her, but I had already become hooked on ostrich feather dusters. The touch is gentler--- almost nothing at all--- using this appliance is very fast and easy on the back, and in the dust palace that is California you need the best help you can get.

You will have to order them. Just search; there are ranches where the birds are raised for such products and taking the feathers does not harm them. The last time I went camping someplace cold, I recall contemplating that humankind has come up with nothing superior to the feather for insulating sleeping bags and really warm down jackets. I need a new duster, though... I've had mine for over 30 years.

Do not even glance at the turkey feather dusters some stores carry. They will not fool your piano or anyone else.

For regular maintenance of your ebony polish finish, I would suggest Cory's Super High Gloss Piano Polish, just as my tech recommended it to me. The full instructions fit easily on the label, and say about what you would think, adding: "Do not spray near strings or tuning pins!" Back comes our clean, soft, 100% cotton baby diaper.

You can order Cory's products from PW's sister site:

I got the polish from my tech, finally getting a big bottle which it appears is going to last forever. I used to know why ordinary spray furniture polish is not the thing to use on pianos. There's some good reason, but it has slipped my mind. The Cory's comes out as a very thin liquid, and I believe it strips off the old polish and dirt as it lays down a new protective wax layer.

Sorry about the long post, ShiroKuro. You would ask me a piano geek question.

+1 for Cory Hi-gloss piano polish.

That's what we use, what we sell, and what we give customers with any new high-gloss piano purchase. It's not fancy or expensive. For most customers, an 8 oz bottle lasts for years. It doesn't damage or haze.

We also like Cory Keybrite. A little 4 oz bottle will last even longer for most customers. It's the only product I know if that is safe to spray directly on the keys of any known keytop material. It evaporates very quickly which is why you can spray it directly on the keys. I also use it for my computer keyboard that eventually doesn't look so fresh.

Thanks for all the comments everyone!

I think I'll try Cory's. BTW, Jeff Clef, I bought the piano used, so no papers from Yamaha or from the dealer.

The sellers had a (very nice) doggie. I think the part that I'm wanting to clean is from that doggie's wet nose. grin

I was told by theYamaha dealership owner and the delivery team to use only ammonia-free glass cleaner, like SpayAway and a microfiber cloth. period. I have used a car plastic scratch cover called Plastech to minimize any tiny scratches.

You might consider investing in a nice piano cover if you don't have one. I cover my piano religiously. Mine is a nice heavy vinyl lined with red felt. The felt helps keep it shiney. I also live in a climate with sometime drastic humidity changes and I think the cover helps the piano deal with those swings. In the summer I have a de-humidifer and on real humid days it takes 8 gallons of water out of my apartment per day even with the air conditioning running. In the winter my humidifier adds about 6 gallons of water. My piano's performance in terms of the sound and action is very sensitive to the humidity level.

Just an update, I got the Corey products and cleaned the whole case. The good news is that the side (curved part of the case) cleaned up very nicely (I think that was mostly dog-nose prints) and a few other spots that were oddly "dirty" also look much better.

The bad news is, wow, the top of the lid is much more scratched than I realized! Although, the good news is that this is the part you don't see when the lid is up, and even when the lid is down, it's not super noticeable unless you get right up against the piano and look down.

Anyway, conclusion: use Corey! smile

Now try the Plastech on the scratched lid.

Thanks for the reminder! I wonder if it would work? I need to see if I can take a photo of the scratchy part. (I mean, to see if the scratches will show up in a photo)
