Inquiry (采购产品): Help with cleaning I have what I believe to be a pyrex oil and vinegar dispenser in which one liquid is contained within an inner chamber and the other liquid surrounds the inner chamber. The container has two small tube openings which are kept closed with cork plugs. I believe that the oil I had in the outer part had turned rancid. When I emptied it to wash it and refill it, it left an unsightly white coating on both the inside of the bottle and the outside of the inner chamber. What can I use to get rid of the coating? If I can't figure out a way to make it look clear again, I will have no choice but to throw out the dispenser (which I am loathe to do). Please advise. Thanks for any help you can offer.
