One complaint: mine has machine oil taste on the deck. i neglected to clean it before coiling, and sure enough, I immediately got that familiar, oily chemical taste at exhale.

I immediately removed just the deck, pulled out the affected cotton, and rinsed the deck, coil and all, under the tap while scrubbing lightly with my faithful old toothbrush (for coils)

Immediately flavor was improved, mission accomplished! Save yourself the extra time and pre-rinse!
