I use it straight up. It has bleach in it so if you leave it full strength
in one spot for too long it will lighten that spot more than the rest so be
aware. Spray it around the hitch pins and use a small scrub brush to work it
all around. Use compressed air or the blower end of your vacuum with the
crevice tool on the end to accelerate the airstream. Blow the 409 out of the
hitch pin field into a waiting cloth. You can do the same around the tuning
pins, just don't spray so much that it runs down into the pin block.

On older grands that aren't worth much, set them up on the flat side, lid
removed. Spray the 409 directly onto the soundboard through the treble
strings and allow it to run down. Use your air stream to move it
around where you want it to go. Work your cloth up with your favorite
soundboard steel. Don't spray it on the bass strings or they will instantly
go dead.

My newest favorite sound board steel is a metal rod out of a hanging file
folder. The little hook on the end of it is perfect for grabbing the rag and
dragging it around.
