Title: Great Seal & Cleaning Ordeal
Review: After nearly 6 months of use, the seal works as advertised. The contents will not spill once the cap is screwed on properly.Effectively cleaning the sealing mechanism housed in the cap is an ordeal. Soapy water leaves a residue that is hard to rinse away...even with a vinegar solution. The question is: As you sip you expensive brew, do you prefer the lingering taste of soap or vinegar?Worse still, forcing hot water through either end will not remove coffee oils. Overtime, the coffee oils form a film which get lodged in the cap that come out the spout. It is a unpleasant surprise.Packaging did not offer cleaning suggestions for the cap.
