Dawn Powerwash has a bit of a cult following in kitchens across the country. If you’ve seen its blue spray bottle on your neighbor’s sink, you know why. It promises to cut through grease, stickiness, and kitchen mess with almost no scrubbing. Just spray, let it sit, and wipe. For some, that ease is worth every penny. But what if you love the spray’s punch but want to save money, avoid trips to the store, or even control the ingredients in your cleaning routine? That’s where a DIY Dawn Powerwash steps in, offering all the convenience (and satisfying suds) in a bottle you refill yourself.
