Nicholal,
You can find scent free washing detergent in many many places for a decent price. Scent-A-Way by HS Scents makes a pretty decent scent free laundry detergent that can be used for regular or carbon clothes. One of the key things about these particular soaps, is that there are no UV brighteners.
Go to
www.basspro.com . Do a search for " Laundry" . This will pull up a few different detergent options.
Good ole Wal-Mart usually carries Scent-A-Way products by HS Scents.
