Thanks. Indeed I use dish washing soap for all the rest of the system, but
hesitated to do so on th PCB board.

Part of this hesitation was the plastic material of brushes - tooth brushes
in particular - that generate the static electricity so easy.

Thank you for the explanation. I shall use it on a Master, which is waiting
for a real proper cleaning job. According to its smell it has been neglected
for years in a filthy shed.

Thanks John!


greetings,
Johan
