A quick question......

[Morris Montego]

I bought some electrical contact cleaner today having previously just had straight WD40 and Silicon lubricant.
A read of the guidelines on the tin said 'disconnect all power". Surely not the battery I thought? A quick google and "Arse Intelligence" told me yes. Surely not when applying to many items?

As long as there is no power going through the switch that you are cleaning it will be ok, if in doubt just disconnect the switch. It is possible to ignite contact cleaner with a spark & dirty contacts are likely to spark under load, better safe than sorry
