Environmental surface sampling can be faster and easier by using the Whirl-Pak pre-moistened Speci-Sponge bag. The sponge is ready to use and is hydrated with 10 ml of neutralizing buffer that will neutralize several surface sanitizers including quaternary ammonium compounds, phenolics, iodine preps, chlorine preps, mercurials, formaldehyde, and glutaraldehyde. To use, squeeze out excess buffer from the sponge - this can be done by squeezing the sponge from the outside with two hands or squeezing the sponge with a sterile gloved hand after opening the bag. Wipe the surface to be tested, return the sponge to the bag, close, and send to the lab for analysis.
