Mukti, From what you described, it seems you need a water softener than a hydrophobic coating. Salt based softeners are good for these issues.

I wanted to use a shimmery pearl backsplash but it was problematic to install. Looking for something reflective. My island is deep blue (sea serpent by Sherwin-Williams), cabinets white with clear glass in second row uppers, fixtures, pulls and knobs all champagne bronze. Hoped to find something more exciting than white subway but I need help and fast so we can install the range hood and the stove!

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too

Greetings from Dream Design, As per your inputs we suggest some ideas -Don't go with too dark backsplash as it will make the kitchen dull after some time and kitchen will look smaller -You can go with marble/tile or even the same counter top like quartz if you use in counter top you can same also put in backsplash as currently it's in trend -take white color with some black/grey lines marble or quartz -or you can go with white designer lines with grooving Sharing some reference pictures
