Any rattan furniture made from high-grade polyethylene does not require a cover because it is entirely resistant to snow, rain, sleet and frost. However, keeping it covered over the winter period will help your furniture look newer for longer.
Most rattan can be left outside for several years, but we recommend covering it for extra protection. When natural rattan gets wet repeatedly, its fibres soften, stretch and weaken. While synthetic rattan is weatherproof but can degrade over time.
Being weather-resistant, rattan is easy to maintain. We recommend storing it out of direct sunlight and under a breathable, waterproof cover. Wash annually with warm water and a drop of detergent. Natural rattan can also be oiled for longevity.
Synthetic rattan made from HDPE (high-density polyethylene) can be exposed to the rain without worry. However, natural rattan should be stored under a cover to prevent the fibres from warping over time.
Natural rattan won't fade from sunlight but can rot and fade if left in damp conditions. While expensive synthetic rattan is fully submerged in dye to retain the colour for longer. And cheap synthetic rattan only has a surface dye and will fade quickly.
Synthetic rattan won't go mouldy. However, natural rattan can, if exposed to moisture. If this happens, clean with a soft brush using 50/50 warm water and bleach. Wipe with a cloth. Rinse with clean water. Dry with a towel. Then leave to air dry.
