Warm water is fine but make sure it’s not hot! Heat damages anti-reflective coatings so it’s best to play it safe. I only ever rinse mine under cold water and then just dry with a plain tissue (no oily aloe vera types), no need to use soap if they’re just a little smudgey. Having said that, a good lens cleaning fluid wouldn’t go astray. Then use your microfibre cloth to polish them, wiping across the lens in one direction.

Everyone’s technique is different but it’s always sad when someone comes in with hazy lenses and it turns out they’ve been washing them under hot water or leaving them on the dashboard. I like to spread the word on the lenses behalf

That glasses washing station is a great idea! All that is is an ultrasonic cleaner which anyone can get, they’re often sold for cleaning jewellery.

Keep up the wonderful work Jo
