Rocker Andrew W.K. knows a thing or two about partying hard, and now he knows how to stay clean before and after doing it. The musician has signed on as the new pitchman for Playtex's 'Fresh + Sexy Wipes,' helping pre- and post-coital couples everywhere feel a little fresher.

W.K. states, "Whether you just finished rocking a packed club or have an intimate encounter after a busy day, this product will make couples feel brand new. 'Fresh + Sexy Wipes' were specially designed to help couples feel confidently clean, before and after they engage in sexual activity!"

For their part, Playtex added, "This exciting new product required the help of someone who could embody the brand's playful yet bold campaign; someone who could party hard, but still be clean when it counted. Andrew W.K. is that someone and we are thrilled to have him on board with us for 'Fresh + Sexy Wipes.'"

In addition, W.K. has lent his backing to the special 'Andrew W.K. Sensory Kit,' which will be sent to 100 handpicked recipients in the media, the rocker's own followers and additional friends of the brand. The kit offers a sensual experience, dramatically hitting all five of the recipients' senses from the packaging to the content inside.

The partnership will carry over to South by Southwest this weekend, as W.K. and Playtex reps will appear at the official 'Fresh + Sexy' Party at SXSW Interactive. The event, taking place tomorrow (March 9) at Austin's Viceland (401 E. Cesar Chavez Street), will find W.K. playing host to partygoers, performing for the audience and offering free product (while supplies last) and drinks. In addition, there will be a one-of-a-kind confession booth on hand, where partygoers are encouraged to share their stories where they could have used 'Fresh + Sexy Wipes.'
