Okay, Natural gas 101.
The product known as natural gas is a combination of many similar gases collected from the same well. The percentages vary, but yes methane is the predominant percentage.

When properly combusted, the only byproducts are CO2 and H20. The concession there is “properly”. It is easier to maintain a burner that is in place, like your furnace or hot water heater, than one that is mobile and banged about willy nilly due to our fantastically maintained roadways.
“Clean” natural gas is either recovered methane or natural gas from the wells that has the condensates, sulphides and other base contaminents scrubbed. How it’s marketed will never please the granola eaters s so too bad.
NG with a high sulpher content is “sour” gas and a corrosive quality.
Propane is also a percentage of natural gas, but is stripped away for it’s own uses.
