Donald Trump washed, folded and sorted laundry Wednesday as part of Salvation Army charity event.

NEW YORK (CNN/Money) - Donald Trump can handle dirty laundry.

As part of a charity effort, "the Donald" spent Wednesday morning in the laundry room of the Trump Tower on Fifth Avenue cleaning socks, shirts and slacks instead of brokering multimillion dollar real-estate deals, according to a spokesperson for consumer-products company Unilever.

Trump's washing and folding was part of a joint effort with Unilever to raise money for the Salvation Army and highlight the company's new 'all' detergent line.

While the gently used clothing that got Trump's personal touch will be donated to the Salvation Army, Unilever has pledged to donate $1 to the charitable organization for each visitor who clicks on its Web site for its new 'all' detergent brand.

Trump has also offered to sponsor a sweepstakes for a four-day, three-night weekend stay at one of his hotels in New York City, which will include a spa treatment and $1,000 worth of new clothes.
