A common question that is asked is if the use of ESD mat cleaners will reduce the life of your ESD mat.
Actually the use of a cleaner specifically designed for your mat such as
ACL Staticide part number 6001 (Digi-Key part number ST1004-ND) or
Desco part number 10435 (Digi-Key Part Number 16-1054-ND) will restore the ESD dissipative nature of the mat and in doing so will make them last longer. It is not recommended to use any cleaners with silicone as a silicone buildup will create and insulative film on the surface of your mat.
