Polypropylene: Polypropylene is a hardwearing, uniformly shaped and coloured material. Special additives add colour fastness. However, exposed sunlight exposure should be limited to retain the original colour. Polypropylene can be cleaned using a mild detergent or a glass cleaner with a soft cloth. Do not use hard woven cloths or abrasive cleaning agents.
Metal: Do not use an abrasive material on the metal. Clean the item with a mild detergent and water. You can dip a soft-bristled toothbrush in the solution or a non-abrasive pad and use it to scrub off any residue or dirt on the item. Dry any residual moisture with a soft, dry cloth.
