I am using Samigon reels which I got new that work very well (always rinsed well immediately after each use) and never gave me trouble if dried. I have some old Paterson reels that came with a bunch of tanks from the auction site but never used them as they never loaded right. They were discolored and I assumed were never cleaned appropriately. Now that I want to try stand development, I need more reels as the tank/reels will need to sit for upwards of an hour. How do I clean the old reels? Can I boil them or put them in the dishwasher? Do I need to use any solvent or vinegar while I try to scrub them with a toothbrush?
