Safe maintenance of stone products - granite, travertine and slate
 

Hi, I have all the above products in my house - kitchen surfaces,
bathroom and kitchen floor respectively. Am avoiding acidic cleaners as
instructed, but how do I clean them - whats best to use - in
particular, the travertine is right next to a lot of chrome, glass and
enamel/porcelain which needs hard water limescale stains to be removed
with acidic cleaners, risking probably definate splilage. Any advice on
techniqes/products gratefully received.
