Housekeeping days Until December 12
Visitors to certain National Trust properties can go behind the scenes during the winter to see the techniques employed by specialist conservators as they clean and restore collections and check for "woolly bears" (carpet beetle larvae). At Mr Straw's House in Nottinghamshire, for example, staff individually clean dozens of 80-year-old woollen socks and pants and more than 50 pairs of gentlemen's pyjamas. On "Putting to Bed" days, activities include the rolling and wrapping of precious rugs, the cleaning of wooden floors using paraffin and vinegar-soaked blankets and much more.
