In a gas furnace does the stainless steel flue chimney ever need to be cleaned? no conversion from coal or oil,original gas.

Good luck not breaking it even if you wanted to clean it.

All liners made of aluminum weaken at the top after so many years of use and would pull apart if cleaning was attempted.
