Surat kitchens get the worst of two climates. Coastal humidity keeps cooking grease soft and tacky rather than letting it harden, so it stays mobile — spreading onto handles, switch plates and the fridge door every time a cloth passes. And the water is hard, so the sink, tap and surrounding tiles carry mineral deposits under that film.
Neither responds to the other one's treatment. A degreaser leaves the scale, a descaler cannot get through the grease. That is why a Surat kitchen can be wiped daily and still look dull.
