A few years ago, we started making our own laundry detergent using Zote (soap), Borax, and Washing Soda.
We noticed that our clothes didn't have the strong perfume odor of detergent anymore, but more importantly, they didn't stink as much when dirty.

I found it much more noticeable with my 'hi-tech performance apparel.' I didn't smell like a wet camel when I got to work.

Another thing I did was to take some baby wipes and put them in a Ziploc bag with a little witch hazel and rubbing alcohol. I keep some in my backpack for those not-so-fresh days.
