As the title of the post said, there has been a food spill inside one of my backpacks, an REI UL 45. Frankly I don't like the pack, and I'd just use my Golite Jam2, but sometimes I have to take the girlfriend with me.
There is chocolate residue on the inside of the pack, quite a bit of it. Can I remove the internal frames and soak the pack in my bathtub? If so, should I just use regular laundry detergent? I live in Southern California and hike the eastern Sierras, San Gorgonio and San Jacinto mountains.
Thanks in advance!
