I put the used funnel into a plastic shopping bag and tied the handles together with a piece of paper towel at the bottom. Next time I need it, it is still clean, and I can tear the bag open if I tie it too tightly, and get another from the kitchen where my wife stores them. I got her into the habit of putting anything into them that would make a mess in the garbage bin. Some of my funnels are nothing more than an old plastic oil container that I have repurposed. Some are 60+-year-old commercially built funnels. Remember the old containers that you used to put water into the battery or the large round flat sided one that you filled the radiator with, I still have them both plus a few more, like an oil can that you fill with oil, and then put the spout into the engine fill tube, push down on a tab and the oil flows out the bottom of the canister through the metal hose into the engine? Yup, got one of those also. Even have a few glass bottles with the funnel attached to the top that oil was dispensed when you were at the full-service gas station. When I pass, the funeral is at 10 AM, Lunch is at noon, and the auction to get rid of all my "stuff" starts at 1 PM sharp. Bidding starts at a penny, and there is no reserve on anything. It will probably run for a week before everything is gone.
