Thanks Nick
Good advice there
My Micro-90 cleaner is from the US and has a list of chems most I cant even pronounce! It seems to do a reasonabl job although grease on the switch was hard for it to shift. Maybe a stronger solution would have been better but I'm wary.
Good point about washing off with distilled water after. I just ran the switch above under the tap and allowed it to dry on the boiler. Then it got more cleaning with switch cleaner and finally the contacts given a last spray with BVWS DeOxit. This is expensive stuff but is the only one that seems to work long term.
It did a fine job on Ct8 valve bases and they came up like new.
