( CNN ) -- The CEO of Levis Strauss , Chip Bergh , has some advice for you : Do n't wash your jeans . As in do n't wash them ... ever . Speaking at Fortune 's Brainstorm Green conference , Chip said he was sporting a pair that had `` yet to see a washing machine '' in over a year . Worried about germs , you germaphobes ? No problem , he says . Just stick your jeans in the freezer once a month next to the frozen waffles to kill off the bacteria . Apparently getting them icy will neutralize the sweat , coffee spills and other bodily fluids that might collect in the zipper or `` seating '' area . He also suggests spot cleaning with a sponge or a toothbrush . While that could work for the stuff on the outside of your jeans , what about all the stuff your body cooked up that 's on the flip side ? Once you get 'em back up to body temperature , wo n't you be warming up those germs again ? Yuck . Jean freezing has become quite the craze in the past few years . It even comes with its own video tutorials and folding techniques posted online by bloggers around the country . Interesting , but somehow I doubt an overnight stay in the freezer is going to silence the filth festival that accumulates on a pair of jeans over the course of wearing them for 30 days straight . The only time I tried jean freezing was during a family fishing trip a few years ago in the Wind River Range . We `` washed '' a load in the river and hung a line up for our laundry to dry overnight . I woke up to unexpected frost and a pair of Carhartts that felt like plywood . If you think it 's hard to pull on your jeggings , ladies , try cracking open a pair of jeans that are frozen solid . Bergh claims that not washing your jeans keeps them in mint condition and helps conserve water . Both noble pursuits . But what about conserving the cleanliness of your lower extremities and not subjecting your colleagues to the stench of dirty denim ? Have you ever cooked bacon or mucked a stall in a pair of jeans ? It 's a gift that keeps on giving . And with this thought , it has dawned on me . He 's not talking to people like my Uncle Warren , who rise with the sun to work the Angus cattle farm that 's been in my family for generations . He 's talking to people who like to look fancy in their jeans . The people that benefit most from not washing denim are the ones who 'll throw down what is for many Americans a monthly salary to buy something they 'll never wash , because , quite frankly , they 'll probably be worn no more than four times before their next new pair of jeans . And listen , science says this `` freezing jean '' phenomena does n't stand up to analysis . In plain English : No , freezing your jeans will not kill all bacteria , but throwing them in the microwave just might . Stephen Craig Cary , a University of Delaware expert on frozen microbes suggests `` you either raise the temperature to 121 degrees Celsius for at least 10 minutes or just wash them ! The latter surely is the best alternative to save energy . '' He adds : `` One might think that if the temperature drops well below the human body temperature they ( bacteria ) will not survive , but actually many will . Many are pre-adapted to survive low temperatures . '' Then again , since much of a CEO 's job is to drum up as much marketing buzz as possible , it 's no wonder that Bergh is making this unsanitary claim -- thereby bringing Levi 's back to the forefront of a conversation . Even if it makes him smell like a farm animal .
Mel Robbins : Levi 's CEO says save water , do n't wash your jeans , freeze them to freshen . Robbins : That 's gross . She says science does n't support this , even though there 's lots of online info on how to do it . Robbins : So what?
