Here at LAMILL (lah-mill) we are currently using the Teflon coated portafilters, and just started using a steam wand of the same. We have seen some immediate downsides to the portafilters, if you take the baskets out after pulling a few dozen shots on them, the underside gets considerably more residue much, much faster. After about 25 shots the bottom is slightly black, at 50 they turn dark black, and at about 75 they are starting to close the holes around the outside of the basket.
So as a remedy we are very proactive about cleaning our baskets throughout the day. My real thought is this, is stainless a better solution? And are the steam wands going to have any similar problems?
(BTW, our portafilters are only covered on the inside.)
Please feel free to point out any other issues that you think may be pertinent.
