Most bags can be washed in cold water and air dried, but no detergent orsoftener, seals the pores of the cloth. The bags are such a tightly woven material that they won't shrink.
Thanks I will try washing with cold water. I just bought a NOS genuine Electrolux bag . There is nothing wrong with the old one I just do not like the idea of someone else's dust in my vac's. Bill,
