In addition to all the advice given above, here are the rules to follow for all jeans containing elastane:
- Space out your washings. Don't wash jeans unless they're dirty. Often, all you need to do is air the garments. Another tip for spacing out washes: Hang your jeans on a hanger by the waistband, to allow the fibers to stretch, especially around the knees and buttocks.
- Wash at low temperature. It's best to wash your jeans by hand, but if you have to use your washing machine, fabrics with elastane can be washed at 40°C maximum, with a special detergent and plenty of water.
- Gentle on the spin cycle. When spin-drying after hand-washing, don't twist the fabric - you'll distort it. Instead, place your jeans between two towels to absorb as much water as possible. Machine wash at 600 rpm max!
- Turn your jeans inside out before washing. Washing jeans causes fabric abrasion. Clothes rubbing against each other, detergent, buttons, zippers, etc. can damage color and fabric.
- Avoid using fabric softener. Don't use fabric softener when washing stretch denim. In addition to damaging your machine, it attacks the elastane that gives your denim its elasticity. As a result, your jeans will curl.
- Don't tumble-dry! But if you absolutely must tumble-dry your jeans to save time, use a "delicate", low-temperature program.
Take the jeans out of the dryer while they're still damp, and finish drying them in the open air.
- Ironing damages and wears out the fibers and should therefore be avoided. If really necessary, fabrics containing elastane can be ironed on position 1 max of your iron.
