Borax, also called sodium tetraborate, is a powdery white mineral that has been used as a cleaning product for several decades.
As far as we know, borax doesn’t prevent fading, what it does do is soften the water (Hard water area like Southern California) It boosts the cleaning power of the detergent because of this. It also removes bad odors from clothing well.
If you’re going to use borax, make sure water is warm enough for it to dissolve. Put some warm water fill in the tub for about 30 seconds and then adding the borax and swishing it around. The rest of the tub is then filled with cold water and detergent.
For medium dark to dark colored jeans, we need to wash them in warm water – hot water. White colored jeans does not need to be washed in warm water – hot water.
1. Pre-treat stain spots if there are any with all fabric bleach like Clorox 2 or Spray and Wash pre-treat solution. Liquid laundry detergent can also be used to pre-treat stains.
2. Turn them inside out and zip them up
3. Use salt if you’re washing for the first time (2 tbsp) This helps keep the dye from running. And preferably just wash with other jeans of the same or similar color. Wash in COLD water, preferably only with other dark colored jeans and use a plant based detergent. If you wash the jeans with other dark clothes that aren’t jeans, make sure they’re not lint transfer items (e.g. towels, etc.)
4. Do NOT put jeans in the dryer ( it will just add to the shrink factor) If you do have to use the dryer, dry on medium, not high heat and don’t dry them all the way, dry them till they’re damp dry – Line drying is best.
5. If you want your jeans to look at good as the day you bought them, only have them professionally dry cleaned.
6. If your jeans are just smelly and not dirty, use a steam iron that can steam vertically or a power shot steamer. This will remove odors without making them suffer the damage caused by washing them in a machine at home.
