I found these urn-sized coffee filters at a restaurant supply/party supply store in my tiny little town- the cashier thought I was loony to be so happy to find them!
I can get them at Sam’s Club and Costco by the case, but then I end up with 1,000 coffee filters taking up much needed storage space. Since I only use about 10 filters a year for tart shells, I just get them at a coffee shop. They usually don’t mind parting with a few of them.
I’m telling you guys - use them for cleaning windows, mirrors, even stainless appliances. They won’t leave any streaks or lint debre. This is an old trick I learned working at McDonald’s in high school.
