The wrong type may transfer bacteria from your cutting board to your wine glasses or leave scratches on your granite countertops. Matching the sponge to the task protects your surfaces and your health, keeping everything from cookware to appliances in better condition for longer.

It is suitable for cleaning more delicate surfaces, such as glassware, worktops and kitchen sinks, which require careful handling to avoid scratches but can still cause significant stains and build-ups.
When dealing with sensitive surfaces, use a blue sponge. It is the least abrasive option and is ideal for very delicate surfaces such as glass or stainless steel, where the goal is a scratch-free shine.
