Mainstream Marine Descaler Solution – 1 Gallon Refill Using a high-quality, safe descaling solution like this one is a great way to keep your boat’s water systems working efficiently. If they’re not regularly cleaned and flushed, they’ll start to develop buildups like mussels, barnacles, calcium, rust, and other water-formed mineral deposits. The result is that flow will be hindered and systems begin to malfunction. You’ll then be looking at much bigger issues that you have to deal with. It’s essential to flush marine engines and air conditioner systems. Color Changing Properties Eliminates The Guesswork How much is too much? How will I know if it's working? This descaler will let you know for sure! When flushing marine engines, if the solution comes out yellow add more. Once the solution cycles through, and remains red, then stop. Won’t Damage Your Equipment or the Environment The formula is biodegradable and non-toxic, so it’s safe to use around all marine environments. It will flush and improve efficiency without damaging seals, gaskets, impellers, or other components.

  • VERSATILE MULTI-PURPOSE MARINE SOLUTION: Mainstream Marine Descaler solution quickly dissolves bio-growth, water scale, lime, tarnishing, and other water-formed deposits on marine engines and A/C systems. Regularly maintaining and flushing these systems with these boat cleaning supplies is a great way to improve overall performance and longevity.
  • IT’S EASY TO TELL WHEN YOU NEED TO ADD MORE: There’s no guesswork with the Mainstream Marine Descaler Color-Indicating solution. If more marine cleaner descaling solution is needed, it will turn from red to yellow, so you’ll know when to add more.
  • GET YOUR EQUIPMENT WORKING OPTIMALLY: Use this marine engine flush to rapidly improve efficiency and open flow passages by flushing bio-growth. It's an internal engine barnacle buster, lime-scale cleaner, tarnish remover, and water-formed deposit flusher all in one!
  • SAFE FOR YOUR BOAT AND THE ENVIRONMENT: This marine descaling solution will NOT damage seals, gaskets, impellers, or other critical components. This boat engine flush cleaner is safe to handle and contains ZERO VOCs.
  • PROTECTS AGAINST TARNISHING: Contains a powerful metal protectant designed to protect against damage, break down, and tarnishing during and after cleaning. The metal protectant and color change indicator provide improved protection compared to concentrated acid, helping to increase operation and lifetime.
