Hello DocWang,
For a Samsung range with a smooth glass surface, you can safely clean it once it has cooled using a soft cloth and a cleaner designed for glass or ceramic cooktops. Standard glass cleaners can be used for light residue, but for best results, products specifically made for cooktops are recommended. Avoid abrasive pads or harsh chemicals, since they can scratch or dull the surface.
Proper care, including using non‑abrasive materials and the right cleaners, helps maintain the finish and keeps the surface performing as expected over time.
This guide provides general cleaning steps and recommended products.

Your trust in Samsung means a great deal to us.
