Donald Trump isn't above doing laundry - especially if it belongs to someone else.

As part of a charity effort, the real estate mogul spent part of Wednesday in the laundry room of the Trump Tower on Fifth Avenue cleaning socks, shirts and slacks.

Trump's laundry duty was part of a joint effort with consumer-products company, Unilever, to raise money for the Salvation Army and highlight the company's new detergent line.

The used clothing washed by Trump will be donated to the Salvation Army. Unilever also pledged to donate $1 to the charitable organization for each visitor who clicks on its Web site for its new 'all' detergent brand.

Trump 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.
