Due to frequent your questions about the need to clean the content of the instrument and on the basis of experience in restoring and "reanimation" of the old piano, long decommissioned and stored in unacceptable conditions (garages, sheds, attics, basements, even balconies, loggias, etc.), think it possible to attempt to provide advice to owners of tools and start-Adjuster. Requiring maintenance tool purity due to two components, namely, hygiene and quality sound. After many years I have been the practice prior to its cleaning piano tuning. I recommend it to all novice tuners, as experienced professionals know it perfectly. I do not recommend do it yourself clients, for whom I cite it only to focus attention to this, at first glance seems simple, but as it turns out, is quite heavy and, most importantly, obligatory and necessary process of each setting. For example, I can bring more technology is very, very "running" tool. Tools, as generally is in pretty good condition, and the following technique can be somewhat simplified.
It is well known that if the piano is played continuously, the mole there feels "uncomfortable." However, frequent cases where the instrument is in the active lately operation, and state it in terms of dust and other contaminants, is terrible. This is because prior to its acquisition, it is stored for a long time poor conditions, and prior to commissioning, maintenance work performed poorly and formally, or were not met at all. An indirect indication of this can be misaligned keyboard, under the keys which mole "ate" pads.
