WEAR, WASH, REPEAT

The secret to tip-top and longer lasting gear is routine TLC. Here’s how to do it.

REJUVENATE YOUR WATERPROOFS

Over time, you may notice your waterproof layers feel steamy and wet inside. Raindrops no longer bead and sluice down the outside as miraculously as they once did. Instead they soak in. This is called ‘wetting out’. And it’s a sign your waterproof needs cleaning, and possibly re-proofing too.

Most waterproof fabrics are laminates, combining microporous membranes with stronger face fabrics that have a hydrophobic coatings, misleadingly called durable water repellents. These rain-shedding treatments wear off and can be masked by dirt and oils. A grimy, saturated face fabric also impedes the escape of water vapour – hence sweat condenses on the inside. Fret not however. A wash is all it can take to restore water repellency and breathability.

Start by brushing off any loose dirt and closing any zips. Next clean out your washing machine’s drawer; any leftover detergent can leave a residue that masks the DWR. Pour in a specialist cleaner, such as Nikwax Tech Wash or Storm Apparel Wash, then set your machine according to the instructions (check your waterproof’s care label too). We’ve used Grangers’ efficient 2-in-1 formula (£11.50). There’s enough in each 300ml bottle to clean and re-proof three items. Once washed, leave your waterproofs to dry naturally. After washing, some brands recommend a low-heat spin in a tumble drier to revitalise the DWR. But it may need replenishing with a proofer such as Nikwax TX.Direct, which comes in wash-in and spray-on forms. Better for waterproofs with wicking liners, the latter also saves an extra spin cycle.
