Curtains are sprayed whilst hung on both sides so there is no need to take them down
and therefore no inconvenience. Dry cleaning will reduce the effectiveness of flame retardancy
and after being dry cleaned 4/5 times they will require retreating. Treatment cannot withstand
wet washing at all. The treatment renders the curtains flame retardant and complies with
BSXXXX and BSZZZZ. A certificate of treatment is issued listing curtains and materials treated.
After treatment the curtains will be quite wet and will require a certain amount of drying time
before they are handled. Approximate drying times are listed on the table below:
