Hello Ladies!
I am Shellie and we make the glass dilators for Dr Pacik! First of all I agree with 23 years, we all do need our sparkle! But on to your question, the dilators are absolutely dishwasher safe, and KatieG, I, like you put them on the little spokes of my dishwasher so they don’t “clank” against anything else. I am not sure what could be causing the cloudiness, but I am betting the suggestion that it is in the water quality is a good one. The dilators are made from extra heavy wall scientific tubing that is the same quality of glass that they use in laboratories and they should just wash easily with soap and water and be sparkling clean. I would ask one additional question, do they stay cloudy forever after that happens or eventually do they return to what you expect to see? If I don’t have an answer I will certainly see what I can do to get you one!
