Clean your Swanstone sink by using
abrasive cleaners such as Comet, Ajax,
Bon Ami, Soft Scrub, etc. Use of a
Scotch-Brite pad, nylon scrub pad,
or Mr. Clean Magic Eraser is also
recommended. Food based stains can
be removed using a 50/50 bleach and
water solution and soaking for 15 minutes.
For rust or other mineral based stains,
products such as Rust-Out or Whink are
acceptable. To restore luster and extend
time between cleanings, Weiman’s Granite
Polish is recommended. Do not use SOS,
Brillo or other metal scouring pads.
