mine don't look to have any screws or caps that remove to expose a screw. I can only think the wiper arm somehow just pulls up or levers off although it looks and feels rock solid
putting a single pole switch somewhere accessible on either the live or neutral wire to the wiper system sounds much more straight forward than having to take the arms off everytime
The wipers are neatly resting on the scuttle so they are fine where they are but clearly the issue of accidentally putting them on is way too great to not solve
if I mange to get them off tonight, I'll work out how easy it will be each time
I've still ordered the pull thingy as it looks handy anyway but as you said jbk probably irrelevant as there is nothing to push on centrally to lever up
