Static Discharge Through K-Pod

[Bob McGraw - K4TAX]

Mix a solution of 1 part DOWNY fabric softener and 1 part water. Put it
in a spray bottle and mist the carpet.  You may need to mist the plastic
chair pad as well.   This should take care of the static issue for quite
some time.  If it returns, mist it again.

Warning! Until that dries, it could be very slippery!
