Guide for Keeping your COS-640STX-E Drop-In Cooktop Surface Spotless and Functional

The COS-640STX-E 24" drop-in stainless steel gas cooktop is a stylish and efficient addition to any modern kitchen. To keep it in top condition, follow these key steps for cleaning and maintenance.

Daily Cleaning

After each use, allow the cooktop to cool completely. Use a soft, damp cloth or sponge to wipe the stainless steel surface, removing any spills or residue. For light smudges or fingerprints, a mild dish soap diluted in warm water is sufficient. Dry the surface thoroughly with a clean microfiber or soft cloth to avoid water spots or streaks.

Using Cooktop Cleaner

For more stubborn stains or grease, use a cleaner specifically formulated for stainless steel cooktops. Apply the cleaner to a soft cloth (never directly onto the cooktop) and gently rub in the direction of the stainless steel grain. Avoid abrasive pads or harsh chemicals as they can scratch or dull the surface. Rinse with a damp cloth and dry completely.

Cleaning Burners and Grates

Remove the heavy-duty cast iron grates carefully and clean them with warm soapy water. For tougher grease or residue on the grates, soak them in hot, soapy water before scrubbing with a non-abrasive brush or sponge. Wipe the sealed burners with a damp cloth; these sealed designs prevent spills from entering the burner area, making cleaning easier. Ensure burners and grates are thoroughly dried before reassembling to prevent rust or damage.

Occasional Use of Stainless Steel Cleaner

Occasionally use a dedicated stainless steel cleaner or polish to maintain the shine and protect against fingerprints and smudges. Always follow the product instructions carefully and polish in the direction of the grain.

Deep Cleaning

For deep cleaning, remove the grates and burner caps. Clean underneath the burners with warm soapy water and a soft cloth. Check for any food debris or grease buildup in burner ports and gently clear with a soft brush or needle if clogged. Avoid soaking the sealed burner assembly in water to prevent damage.

Checking Functionality

Regularly test the electronic ignition to ensure burners light properly and flames are steady and blue (not yellow or flickering). Inspect knobs and control settings for smooth operation. If any burner does not ignite or the flame is irregular, consult the user manual or a professional technician.

Routine Maintenance

Wipe spills promptly after each cooking to avoid buildup. Periodically inspect the cast iron grates for rust and apply light oil if needed to protect the finish. Keep the area around the cooktop dry and clean. Follow any additional maintenance guidelines specific to the manufacturer’s recommendations or warranty instructions.

Additional Tips

  • For deeper scratches, consult the manufacturer for repair options.
