Nikwax Base Fresh deodorises and maintains freshness by preventing the build-up of odours in base layers when in use. Accelerates drying and improves the cooling efficiency of all base layers. Fabrics treated with Nikwax Base Fresh are also more resistant to stains and day-to-day soiling. Using Nikwax Base Fresh allows base layers to be cleaned with your usual laundry using conventional detergent removing the need for a separate wash and allows the use of aggressive detergents and cleaners to remove stubborn stains without compromising the performance of base layers.
