Are swabs available for cleaning static sensitive electronics?

Yes, Chemtronics offers a full line of ESD swabs. They include foam, knit polyester, or knit microfiber heads with static dissipative handles. The proprietary handle material has surface resistivity of 1.0 x 10_10 ohms/sq, and will dissipate 99% of (5 kV) charge in 0.5 seconds. This avoids static generation, and can dissipate a charge when the user is grounded.
