Ouster 3in1 Hot Tub Cleaner: SPECIAL CLEANING CONSIDERATIONS FOR HOT TUBS. Like all appliances, hot tubs require periodic maintenance. Behind the scenes, interior plumbing lines move water throughout the spa to dozens of jets. When not in use, these lines become an area of buildup from non-living nutrients such as lotions, sunscreens, cosmetics, sweat, and other gunk. It's a natural occurrence common with any closed-loop warm water vessel like portable spas. Most hot tubs are heated between 98 and 104 degrees, creating a great soak but with unintended consequences. We highly recommend you if you experience poor water quality symptoms: black, gray, or white flakes or gunk in the water, filters, or shell surface; noticeable odor; cloudy water on a regular basis; buying chemicals more frequently; itchy skin after soaking; or if your hot tub is older than 1 year or was purchased used. PURGE HOT TUB 2-3 TIMES A YEAR. Ouster Hot Tub Cleaner is specifically formulated to 'scrape' the interior pipes in your portable hot tub. It reduces gunk while keeping your plumbing jets clean and odor free with just one treatment every 3-4 months. Bio Ouster works with all major sanitizer systems and spa types.
