First, I started with baking soda and water, then moved to baking soda and vinegar, using a rough scrubbing pad that wouldn’t scratch. I wanted to start gentle, and without chemicals, to avoid damaging the material, which I discovered after looking under the sink was something called Silgranit — a patented granite composite made by Blanco.
