I have a few drip tips (just started using 'em) and put one I was using with a menthol juice onto a carto with a sweet juice in it and it was NASTY. YUCK! I had rinsed it off really good in super hot water and it was still way nasty. Anyways, anybody ever put 'em in the dishwasher? I hope it works 'cuz I got one in there right now. What'd'ya think?
