## 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.

### ⭐⭐⭐⭐⭐ Amazing
*by S***E on April 25, 2025*

This stuff worked so well! My 50hp Honda outboard was having cooling issues and I thought it was going to have to be rebuilt which would have cost a fortune. I set up a 5 gallon bucket with a 800gpm pond pump, removed lower unit and pushed a 1/2" hose from pump onto the cooling water tube sticking out bottom of engine. Also used a 3/16" barbed fitting to extend the tell tale hose to bucket. Removed thermostat. Then taped a trash bag with the bottom cut off onto the engine and draped into bucket. Mixed Rydlyme 50/50 with water, and ran the pump for 3 hours. The water almost turned gray there was so much salt and junk in it! When I dumped the bucket there was a thick sediment in the bottom too. Flushed the engine really well with fresh water right away. We just took the boat out and it's like a new outboard! So happy!!
