<< A customer of mine has an old upright that the previous owner used brasso or something on the bass strings. It is encrusted between the windings. What can be used to clean these up? Is ammonia ok? >> No, it will simply waste your time and stink up the piano. You will have to either replace them, or take them loose and flex them around to loosen the crud before bringing back up to tension. Even then, it is iffy that it will help.
