      Full content visible, double tap to read brief content.

      We've been struggling with typical foul odor coming from the hot water line each season we opened our boat. And each season, we try straight bleach and then vinegar. It works ok, but still a slight smell on your hands. Decided to give this a try and, wow! It's concentrated, so we started with an empty fresh water tank, filled to around 20 gallons, thinking we would have to run the water for a while, added the dosage according to instructions..not 3 minutes into that start of the flush, the hot water smells normal already. We flushed the water through all our sinks and let it sit in the lines while we cleaned the exterior. At the end of the day, the water still smells normal, "clean" ... Almost to the point that I would drink it if I had to, straight from the tap. This has been the best product we've used so far. We've tried other brands that claim to clean odors, but this one really worked for us!

      STAR BRITE Aqua Water Shock for Boats & RVs is like a refreshing spa day for your water system, giving it the ultimate cleanse and revitalization! This powerful treatment tackles the buildup of grime, algae, and those mysterious odors that can lurk in your tanks, ensuring that every drop of water you use is as fresh as a morning dew.

      Just a quick application and you’ll be amazed at how it transforms your water supply from “yikes” to “yes, please!” It’s easy to use, so you won’t need a PhD in chemistry to get the job done—simply follow the instructions, and let Aqua Water Shock work its magic. Plus, it’s specially formulated for boats and RVs, meaning it’s tough enough to handle the rigors of life on the water or the road, while still being safe for your plumbing.

      Using this product not only extends the life of your water system but also gives you peace of mind knowing that you're using clean, safe water for cooking, cleaning, and even brushing your teeth. If you’re tired of dodging that funky smell and ready to upgrade your onboard water quality, give STAR BRITE Aqua Water Shock a shot. Your taste buds (and your nose) will thank you, and you might even feel like you’re sailing on a cloud of purity!

      Solved my bad smell problems. I even left water in it for a week and a half after a trip, still smells fresh. Usually it will develop a rotten smell pretty quickly, especially in the water heater, not anymore. With an ounce treating 10 gallons, this stuff is just what I was looking for.

      This is Chlorine Dioxide, it is not the typical cheap bleach water treatment. Use it as a water additive for its benefits or add to anything that holds water to keep it fresh or clean it up. Really the only way to go if it's water you are going to drink!
