[CAUT] Cleaning solution

[Jim Busby]

Gerry,

Good post.

So here is what I'm finding out, so far;


1.       Simple Green and Murphy's Soap seem to be safe for anything.

2.       Alcohol, ammonia, windex, may hurt some finishes.

3.       Cory products may be good (A refinisher here told me NO on these due to buildup.

4.       Microfiber High Performance Polishing cloth? (Sounds good. Got to get me one)

Anything else?

Jim

Mike,
I did a bunch of work and piano surface cleaning & maintenance formulations many years ago so here's my 2c.

Do Not use ANY ammonia formulas on any high gloss finishes. Many of the Windex formulas and almost of the off label brands contain ammonia in the formula. It does dull the high gloss finish.

For basic cleanings just use water. IF there are fingerprints, oils or derrivatives, use any neutral cleaning agent.  Eg: Simple Green at appropriate dilution. You can also use the Cory Care products. He does have ok formulas although the pricing may impinge on the school budget.
With any water based elixers always use the minimum, think moist rather than wet amount on a cheese cloth material. Cotton cloths ( towles, t-shirts etc. are made to absorb. They waste alot of fluids by wicking up the fluid into the cloth rather than holding/carrying the fluid to allow spreading onto the surface to be treated.  Paper products are wood based and always cause scratching of some sort.

Hopefully this is not newsworthy but figured I'd mention it anyway.
Nitro/Satin finishes on SS are harmed by certain chemicals, thinners, alcohols etc. so a BIG word of caution and stay away.

Back to the trenches.  =)
Gerry

Seems to work for Oberlin.  Although I think all their Steinways are satin.  I haven't tried it.

They do have one or two Hamburgs.  I can ask Robert how they treat them.  Maybe just a damp cloth followed by a dry one.  That's what I would do on a high gloss.

Oh Oh, I've heard that ammonia will cloud hi-gloss finishes, the same with Windex.  Don't know if this is reliable info or not......
