Spent 3 hours hunting a leak in my mug shelf and it was a hairline crack near the handle
Last Saturday I pulled everything off the mug shelf in my kitchen in Tucson because a puddle kept coming back under my green camp mug. I ran water through it 4 times and it stayed dry, so I blamed the shelf, then the wall, then the seal on the window. Turned out there was a 1 inch crack right where the handle meets the body that only let go when the mug was full and tipped a certain way. How do you all spot hairline cracks without soaking everything in the sink first?
