Hi I wonder if you can help me. Every time I use the mug press (Genie III mug press) I get white spots on the mug. On the ceramic mugs it is ok as it washes off. But when I use a stainless travel mug I cannot wash the spots off and it doesn’t look great. Do you have any ideas on how to correct this. I have tried using PTFE Teflon sheets around the mug as well as baking sheets but to no avail. It is starting to make our work look poor.
Many thanks
