We buy a lot of new disposable plastic containers/drainers etc each pesach and then keep them for the year. By the next pesach they are usually all ready to be destroyed after 12 months of hard use, so we cycle these things each year- reduces pesach storage and gives a routine to the kitchen utensils. Highly recommended- a system that can't go wrong. I have a list of things that need ordering from Amazon /online 6 weeks before pesach and a reminder to do this on my calendar.
