Frequently Asked Questions

How often should I descale my Keurig K-Duo?

What should I do if my coffee tastes off after cleaning?

Run multiple plain water cycles to flush out any residual cleaning solution or mineral deposits that may affect flavor.

Yes, but it’s best to use descaling solutions periodically to remove mineral buildup that water alone can’t eliminate.
