Clean Eraser is a great product.

Also love "Dobie" scouring pads. Abrasive enough to clean difficult stains but mild enough not to stratch, any surface.

Both are Felix Ungar approved!!!

My Father-in-Law used to have a glass of Single Malt Whiskey every night and God forbid you should wash up his glass, he used to refill it every night and I never saw it washed. I don't think anyone had the courage to touch it.

I sprinkle some Ajax in the cup, scrub it quickly and Voila.
Clean and like new!

That's exactly what I do, and then pop the cup in the dishwasher.
Easy peasy.

If you just rinse the mug as soon as it's empty, no stains.

We get out stains and other marks with Barkeeper's Friend.

A little soft Scrub should do it.
