Have you wondered how you clean dust and dirt out from under the strings? There is no vacuum that will pull the dirt up through the strings. It is best to have me do this cleaning but I will show you the process. The important tool is a long strip of steel to push a rag under the strings.

The soundboard steel works the cloth under the strings and pushes it over to the long side of the piano where it can be pulled out and cleaned.

A paintbrush makes a great tool to remove dirt from between the tuning pins and around the hitch pins. Keep a vacuum close as you use the brush.

Here is the cleaned out soundboard.
