When the weather turns dry and the humidity is low, static can occur.
The tendency to generate a static charge at low humidity varies from carpet
to carpet. Some of the new carpets have antistatic agents built into the
fiber. Others use very fine metal wires or even a conductive latex within
the carpet to carry off the static. Antistatic protection of this type
usually lasts for the life of the carpet.
Antistatic Spray and Antistatic Spray SR give good protection against
static buildup. The protection is not permanent but can last up to six
months or the next cleaning, depeding on the traffic.
