I used Discwasher fluid on my 103D using the Diskwasher SC brush. Anything stronger may damage the old style rubber at the other end if the cantileaver. Dont get fluid on the cantileaver. If you have the tone arm loose you can use a firm brush like a Discwasher and go in a motion from back to front on the stylas. The cantileaver is very complient and by keeping the tonearm loose you only have the traching weight pushing on the brush.
I would be careful with LAST because that is a stronger solvant. It is good for getting hard muck off.
