Trouble is, after a while the stains start to get pretty back over the
viewing window so I'm looking for a fairly non-abrasive means of
getting those stains off. Gentle baking soda scrub ???
Any ideas are very much appreciated.
TIA
Try bleach. Let it stand in the carafe overnight, diluted about 5:1
That works fine for white coffee and tea cups.
Try Trisodium Phosphate, i.e. dishwasher powder. Dissolve some in hot
water and let it stand in the carafe over night.
