Most denim purists simply won't wash unless literally forced to. Their jeans might be found stuffed in a freezer for a couple days, or sprayed with Febreeze™ from time to time, or air dried outside; either way it's as close as their jeans will ever come to being 'cleaned'.
After a minimum of 4+ months of constant wear (or longer if your jeans aren't too dirty), turn your jeans inside out and soak for 30-45 minutes with a premixed combination of water and 3x1's Denim Solution or castile soap (Approximately 30:1 ratio). Rinse thoroughly (by hand) with fresh water - make sure the soap residue is gone. Lay the garment flat, cover with a clean, dry towel, then roll up the jean + towel to absorb any remaining surface water - leave for 15 minutes. Unroll towel, and hang dry overnight (or until completely dry).
After a minimum of 30 days of constant wear, turn your jeans inside out and soak for 60 minutes with a premixed combination of water and 3x1's Denim Solution or castile soap (approximately 30:1 ratio). Don't agitate unless you're needing to remove specific stains - simply soak, then remove and rinse thoroughly with fresh water. Wring excess water from rinsed jean, making sure any/all soap residue is gone. Hang dry in a shower or tub to ensure remaining water drains overnight (or until completely dry).
Try to go as long as you can without washing, but when you've reached that point, it's time to wash. Pre-mix the suggested amount of 3x1 Denim Solution (given the load size) in water while using your machine's 'DELICATE' cycle. Let the machine cycle through to completion, DO NOT use an extra spin cycle. Gently shake out your jean and hang dry overnight (or until completely dry) if possible. If you insist on machine drying, we advise against it unless it's a stretch denim product, but if you absolutely have to - let them hang dry first and then touch-up in the dryer briefly, on low/medium heat, to de-wrinkle (approximately 10 minutes).
