Most people are chronic over washers with more than six billion loads being done per year in the U.K according to the Office for National Statistics. But sometimes an item doesn't need a wash, it just needs a freshen up and whilst your pet will be enjoying the natural bouquet around the bed, you might disagree. Hanging it outside so it can have the full benefit of Mother Nature to give it a blow through could be enough to take any unwanted aromas away. If however she's not in the mood, try popping your bed cover in a recycled plastic bag and in the freezer for a couple of hours. It seems that odour causing bacteria don't appreciate the Arctic like conditions and tend to die off. Obviously bring the cover up to room temperature before refitting it. Also, with the aid of some precision purging, any annoyingly visible marks will be vanquished by doing a little bit of spot washing and will also prolong the time between washes.
The much bigger problem though is how items are dried. With most tumble driers having only a C energy efficacy rating and more than14 million homes owning one in the U.K. the use of these energy vampires should be avoided. Washing and drying a load every two days creates around 440kg of CO2e each year, which is equivalent to flying from London to Glasgow and back with 15-mile taxi rides to and from the airports.
Line drying is not only better for the environment, it's better for your pocket and your textiles.
There is overwhelming scientific evidence to confirm that tumble drying damages your fabrics. To see for yourself, look in the lint tray at the results of tiny tears in the fabric fibres which will eventually cause your item to fall apart. Drying fabrics at 150°F only twenty times makes it twice as easy to tear. Towing the line means that you don't even need your own little patch of green to be green, indoor drying racks are a good option if you can't line dry outside with ceiling ones being the most efficient.
This is one of those products that needs to be washed in an environmentally friendly way. That said, it's all quite simple. Wash on a wool cycle, use an appropriate wool wash and no fabric softener then line dry outside if possible on a windy day. Easy. However you can always just brush it, spot clean it and put it out on the line to give it a freshen up.
