Safe to touh an aluminum boat trailer or stainless boat prop?

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

Can it be used in indoor plumbing

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

Is this safe for plastic and the pads of an evaporative cool?

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/

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?

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.
