## Overview

RYDLYME Marine Biodegradable Descaler is a concentrated, eco-friendly liquid solution designed to rapidly dissolve tough marine scale deposits like calcium, lime, rust, barnacles, and mussels. Safe for most metals except zinc and magnesium, it’s ideal for cooling systems, heat exchangers, and condensers. With flexible dilution ratios and a quick 2-4 hour circulation time, it delivers professional-grade cleaning power while being non-toxic and biodegradable.

## Description

This item contains (1) single gallon of RYDLYME Marine Biodegradable Marine Descaler. This product is to be diluted 1:1 with water and water only prior to use. For periodic maintenance cleaning, it may be diluted further to 1:3 with water. It is also available in case quantities of (4) single gallons. No ready-to-use item is manufactured. RYDLYME Marine works most effectively when circulated through an application such as a raw water cooling system, oil cooler, or A/C condenser in order to rapidly dissolve any unwanted marine fouling of water deposits. RYDLYME MARINE is safe on virtually any metal or material except for zinc and magnesium. Make sure to blank anodes or plan on replacing them after cleaning the cooling system on a marine engine. For complete instructions, SDS, and Specifications please review the available Technical Documents below or visit www.RYDLYMEMarine.com for further information and to contact a product specialist.

Review: These RYDLYME Marine Biodegradable Descaler (typically sold in 1-gallon or larger bottles) is hands-down one of the most effective and safest tools for keeping your boat's cooling system, heat exchangers, outboards, inboards, and other water-cooled components running cool and efficient! This stuff is a game-changer for dissolving stubborn scale, calcium buildup, rust, barnacles, mussels, sand, and mineral deposits that clog passages and cause overheating—without the harsh risks of traditional acids like muriatic. It's fully biodegradable, non-toxic, non-corrosive to most metals (when used as directed—note: remove zinc/magnesium anodes first to avoid pitting), and safe enough that you can handle it with bare hands. No nasty fumes or gloves required for basic use, and it's eco-friendly for marine environments. Application is straightforward: dilute per instructions (often 1:1 or as needed), circulate through the system (muffs for outboards, pump setup for inboards/AC), let it work (foaming/bubbling shows it's actively dissolving gunk), flush thoroughly, and you're done. Users report dramatic results—overheat issues vanish, "pee" streams flow strong again, cooling passages look factory-fresh, and engines run noticeably cooler. One flush pulled out cups of solid debris from heavily fouled systems, restoring performance like new. Many boaters make it an annual or bi-annual ritual, saying it's worth every penny compared to downtime, repairs, or less effective alternatives like vinegar or Salt-Away for heavy scale. The concentrated formula works fast (often in hours or overnight), cleans up to 12x quicker than some competitors, and holds up across seasons of salt, brackish, or hard water use without damaging seals, gaskets, hoses, or rubber components. Cleanup is easy—just flush with water—and it leaves no residue. If you're dealing with overheating, reduced water flow, or preventive maintenance on your marine engine or AC system, RYDLYME Marine delivers outstanding, reliable results that far exceed expectations. It's trusted by pros and DIYers alike for good reason—proven over decades, incredibly effective, and genuinely safe. Don't settle for cheaper hacks; this is the real deal for protecting your investment on the water. Highly, highly recommended—grab a gallon and thank yourself later!

## Questions & Answers

**Q: Safe to touh an aluminum boat trailer or stainless boat prop?**
A: It's safe on aluminum outboard powerheads so I'm sure it's safe on a aluminum trailer and it won't harm the stainless prop at all

**Q: Can it be used in indoor plumbing**
A: Well depends on problem , drain clog no won’t work . But if you have a plumbing coil that has mineral scale from hard water yes it will work . Also any water system closed loop style will clean internal deposits like a heating coil on boilers . Good luck

**Q: Is this safe for plastic and the pads of an evaporative cool?**
A: This product is safe on plastic. For an industrial application, we would recommend using our Industrial Descaler, RYDLYME. https://www.apexengineeringproducts.com/product/rydlyme-biodegradable-descaler/

**Q: I used it to flush a hot water heater. Two weeks later the hot water smells while the cold water doesn't. How long does the smell / odor last?**
A: Usually a smell from a water heater means the anode rod, has gone bad.  You can flush it many times.   It will only come back….   Change the rod.

*by H***T on 13 November 2025*

Descaler for certain. Great Descaler for my 20 hp engine. Followed the instructions on dilution, let it run overnight. Cleaned engine inside and now works properly. No more limp mode or overheating. Cheap fix rather than taking it to the shop.
