Here’s a little secret. You can use an RV water filter too. They’re cheap, everywhere, and designed to make “city water” taste less like a swimming pool. But they also soften water.
Grab a Camco or a similar brand. They screw onto your hose with a quick-connect. They cost like fifteen bucks. That’s almost free.
Is it perfect? No. But for a quick wash between details? It’s a lifesaver. Your mileage will vary, but for the price, it’s a no-brainer experiment. Just swap the cartridge every season.
