Demiwise Oven Liner Bottom 16x24 — Heavy-Duty Non-Stick PTFE Mats, BPA/PFOA Free (5 Pack)

Discover a smarter way to protect your oven with the Demiwise 16x24 inch oven liner. This thick, heavy-duty non-stick mat sits on the bottom of electric and gas ovens, catching drips and spills before they bake onto racks. Its smooth, easy-clean surface makes wipe-downs feel effortless, helping you keep the oven looking fresh after every bake.

Why this liner stands out

Designed for real-life kitchen use, the liner combines durability with practicality. A tough, waterproof surface seals in drips while the edge-to-edge coverage minimizes forgotten spill points. The result is a cleaner oven interior and a faster cleanup, so you can focus on cooking your next meal rather than scrubbing the last one off the bottom.

• Thick, resilient construction with a 0.28 mm PTFE-coated fiberglass layer for lasting protection
• 100% BPA- and PFOA-free, designed to resist everyday kitchen heat and messes
• Reusable and long-lasting—typically 10–100 uses depending on care and cleaning method

Versatile, cut-to-fit design

The liner easily cuts to fit different oven models and layouts, making it a versatile addition beyond the bottom of the oven. It works as a practical companion for ovens, toasters, grills, air fryers, and baking pans. Sold as a 5-pack, you can keep a spare on hand or rotate while one cleans.

• Cut-to-fit size for a custom, spill-free edge without gaps
• Great as a multi-appliance protector—use under grills, air fryers, and pans
• Place on the lowest rack or tray for safe use, away from heating elements

Easy care, bold convenience

Cleaning is simple: wipe with a damp cloth or place in the dishwasher for a deeper clean. The surface is non-stick and waterproof, catching grease and spills so they wipe away quickly. When wear becomes visible, replace to maintain performance and peace of mind.

• Dishwasher-safe, quick wipe-down, and effortless maintenance
• Heat tolerance up to 500°F / 260°C for reliable performance
• Eco-conscious and economical—reusable, cut-to-fit protection for years of use

With Demiwise, you’re choosing a practical kitchen companion that helps you keep the oven clean, saves you time, and offers flexible use across several appliances. It’s an approachable upgrade for everyday cooking, baking, and roasting—without overpromising results.
