What is best to clean white quartz with- quartz company said not to use washing up liquid

as it’s greasy.

Cif, that’s I was recommended by the company that fitted mine.

As an everyday cleaner?

Specialist granite cleaner or clean ology soray

I just use Method surface cleaner on it. For anything stubborn, I use Barkeepers Friend. I wouldn't use Cif, too harsh.

I've had my worktop a couple of years and it's still immaculate.

They told me Cif and window cleaner. The only thing they said not to use was bleach.
