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.
