Tip

When cleaning stainless steel surfaces, rub in the direction of the grain of the metal.

Brushed stainless steel sinks have faint lines or “grain” due to the manufacturing process.

Always follow those lines to prevent additional scratches.

It can also cause damage, including scratches, pitting, and discoloration to some nonporous surfaces.
