## 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.

### ⭐⭐⭐⭐⭐ Will buy Again !!!!!!!!
*by  on Reviewed in the United States March 1, 2026*

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!

### ⭐⭐⭐⭐⭐ Engine cooling descaler
*by  on Reviewed in the United Kingdom September 5, 2025*

Brilliant. Descaled my motor boat diesel engine coolers. Saved £££££s avoiding strip downs of coolers. Inspected cooler internals with inspection camera after flush. Spotless & engine temps perfect.

### ⭐⭐⭐⭐⭐ Rydlyme is a must if you run in the marsh!!!!!
*by  on Reviewed in the United States March 10, 2026*

This stuff works I had hardly any flow out of my 2007 Yamaha this cleared up a huge blockage and push it right out. Peeing like a brand new motor. Keep this stuff around ya if you run in the marsh trust me. 100% better then any other marine flush on the market. Highly recommend using 1 time a year. Keep them water passages clear for longer outboard life. Attached is what I could see this stuff pushing out.
