Where grease poses less of a problem, in food preparation areas, for example, choose grease-resistant mats for long service life.

Other processes can be used to obtain grease-resistant paper, such as waxing the paper or using fluorine-based chemicals.

For more than half a century, manufacturers used perfluorinated chemicals virtually unregulated to make nonstick cookware, rain-repellent clothing, grease-resistant packaging and hundreds of other products.

THE chemical used to make Teflon as well as grease-resistant packaging and stain-resistant textiles has been the subject of a lot of bad news recently.

Fluorotelomers are used in "fire-fighting foams, grease-resistant food packaging, leather protectants and stain-resistant carpeting and textiles."

Water repellent and stain resistant (with oil- and grease-resistant gloves due next fall), they do not stain in the rain, as most leather gloves do.
