Gas stoves fill the air in your home with particulate matter (pm), which has been found to increase cancer risk in the long term.
So next time you buy a stove, consider choosing an induction stove.
Btw, gas stoves being better or faster than induction is a myth.
One thing I like about gas stoves is the ones with sealed burners are a hell of a lot easier to get clean-looking than the glass tops of electric stoves. They get nasty so quick I prefer the old-style coil ones.
For your problem I’d try soaking a paper towel in CLR cleaner. It’s probably lime from the water and not salt.
