Hello, my name is Heather with KOHLER Customer Service. I am happy to assist you with your sink question.
The recommended cleaning products to use with K-5924-4-96 are our Kohler Cast Iron Cleaner, Fantastik Antibacterial Heavy Duty, Formula 409 Antibacterial all-purpose, Green Works All-Purpose or Soft Scrub Gel with Bleach. If you follow our recommended care guide the well water should not affect the sink. Here are our recommendations for caring for your Kohler Cast Iron sink. Rinse thoroughly and use a soft cloth to wipe the product dry after each use, in the rare occurrence of stubborn stains, use abrasive cleaners sparingly, do not use steel wool, wire brushes or abrasive sponge pads, be careful not to leave dirty dishes, coffee grounds, tea bags or other staining materials in contact with the enamel surface for extended periods of time, consider kitchen sink accessories such as bottom basin racks and rinse baskets to help protect the surface from scratches, do not store open containers of cleaners or chemicals such as acids, bleach, sodium chloride, lye, toilet bowl cleaner, drain cleaner, or hard water stain removal products under your sink. Success with cleaners and procedures is dependent upon such factors as the hardness and temperature of the water, using exact measurements of ingredients, changes in cleaning formulas and the condition of the product being cleaned. Since there are variations within these factors, Kohler cannot guarantee the effectiveness of the formulas mentioned.
