My kitchen drawer has been sticking for months and it drove me nuts. I saw a tip about rubbing beeswax on the metal slides. Tried it today and now it glides perfect, lol. Such a simple thing that cost almost nothing. Really shows how little fixes can make a big difference.
Applied beeswax to my kitchen drawers two years ago. They still open and close without any sticky residue. Honestly, it's one of the best home tricks I've found.
