My mother-in-law taught me this trick to clean grey dust and grime off window blinds before opening the house for spring with 0 effort. Here’s how it works

gray, dingy, or just tired after winter, this is worth trying before you throw bigger effort at the problem. It’s inexpensive, fast, and easy to fit into real life—which, as someone balancing work, errands, and trying to keep a house reasonably fresh, is exactly the kind of spring-cleaning win I’m always looking for.
