Autumn rain is here, and a waterproof jacket that wets out usually needs cleaning and re-proofing rather than replacing. Which wash and waterproofer should you buy on amazon.co.uk?
The short answer: clean the jacket with a technical wash first, then add a wash-in or spray-on waterproofer. Household detergent can leave residues that attract water, so skip it for waterproof kit.
