Everything will dull your knives. The question is how quickly. CleanTi’s crystalline structure is considerably softer than conventional metal boards, with hardness similar to bamboo or some hardwoods, helping reduce blade wear during normal use. Yes, you will have to sharpen your knives more often than if you use a plastic chopping board but it's a small inconvenience our customers are willing to deal with to avoid ingesting microplastic and other toxic residues.

Yes. Fine marks are expected because CleanTi is designed to yield slightly under a knife rather than grind against its edge. These shallow, cosmetic marks do not affect the board’s strength or hygiene.

The non-porous titanium surface gives food residue and moisture fewer places to collect. Water or acidic foods may leave temporary marks if allowed to dry, but these can normally be removed during washing. Titanium has also natural anti-bacterial properties.

Rinse it under running water, wash it with detergent or place it in the dishwasher. For stubborn surface marks, gently use an abrasive sponge or fine steel wool.

CleanTi is thin and easy to store. The Medium board measures 35 × 25 × 0.15 cm and weighs approximately 580 g.Titanium is roughly half the density of steel. Looking at the product weight it's an easy way to understand if it's made of pure titanium or the seller is false advertising steel or coated products.

Titanium does not rust, crack or absorb moisture. With normal cleaning and care, CleanTi is designed as a lifetime chopping board, although its appearance will naturally develop with use.
