System 4 Visor

[Richard P]

I'm loosing the anti-mist layer on the inside of my BMW System 4 visor and it mists up terribly in the rain (not good when negotiating my way across Poland in some awful weather)

The Visor is otherwise good and unscratched so I am loath to buy another at this time.

Any advise on how to renew / refresh / replace

Cut a potato in half (cheap in poland) and rub the visor with the wet part, or a smear of washing up liquid on a cloth and rub the inside of the visor until it's clear.

These are just cheap and cheerful solutions not permanant, and need to be redone on a regular basis.

If you pass a Lidl on your travels see if they've got some "W5 nano solution"-its a cleaning system for car windscreens (so dont use the big scratchy block that comes in the box or you wont see sh1t) but the spray on stuff works great on the inside and outside of a visor. works well on specs too.
