I regularly make soup in my titanium pot from a powdered broth for dinner. I add tuna packet and olive oil. Needless to say, this leaves a pretty strong scent/flavor to the mug even after rinsing it diligently. This makes for interesting and off putting coffee in the morning. So I either bring an additional mug or figure a way to clean it well. I have tried Dr. Bronner’s soap and small piece of 3m scrub pad, this works to visually clean it but the taste is still left behind.
Any ideas on this?
