I forgot to say that I don't put anything on my wax paper, parchment paper or acetate/film when I pipe for practice or for transfers. I saw that Hani (Haniela's) wipes her mixer bowl with vinegar. Although I don't do that I know what she is saying - vinegar equalizes/sanitizes (don't know the words to use) and ensures the bowl is clean. I know that utensils have to be "clean" or the RI won't come out. All of my utensils, except the mixer bowl and attachments, go in the dishwasher - sanitized. I use a clean cloth to clean the mixer bowl/attachments. No, I don't go to extreme measures. lol Oh, I hollered both times when my daughter put my beaters (yes two) in the dishwasher. Big butt groan...
