You open the tap on the boat, and it tastes like the tank it came from. Chlorine, plastic, that faint metallic aftertaste. You've tried a filter, a different bottle, and you're still not drinking it with confidence. This 237ml bottle fixes the taste at the source. The biodegradable formula strips out chlorine, sulphur, plastic, and metal odours so your water actually tastes like water. Thirty millilitres treats 75 litres, so one bottle covers a full tank on most boats and RVs. Use it as often as you need – before a long trip, after topping up from a tap with hard water, or any time the glass looks fine but the taste isn't. It's not a one-and-done fix; it's the small habit that keeps your drinking, bathing, and ice water clean every single day. Add to cart and stop second-guessing that first sip
