Latex. Orion's care page for latex clothing specifies hand washing in lukewarm water, about 30 degrees, with a grease-free detergent. Grease, perfume, oils and certain metals – copper, brass and bronze – react with latex, and too much direct sun can make the surface dull and faded. Completely dry garments are lightly dusted with latex powder so the surface does not stick together. For shine, Orion sells a silicone spray, not an oil.
PU-coated polyester. According to Orion's customer information for the Black Level garments: hand washing in clear, lukewarm water with a mild detergent, drying with a soft lint-free cloth, and storage hanging on a hanger since the glossy surface creases easily. No powder is needed.
PVC. Orion's material guide says PVC should be protected from prolonged light and sun and that an initial smell disappears with airing. Follow the care label in the garment for washing.
Wetlook. Gentle hand washing with a delicates detergent according to Orion for the Cottelli and NO:XQSE garments.
Store the materials apart. Orion's customer information says the garments should be stored on their own and not together with products made of other materials, to avoid chemical reactions. So a latex stocking and a PVC skirt that are sold to be worn together should not be stored together.
