Our Aizome products are dyed authentic Japanese indigo "Ai". For the first few tiems, the colour comes off on everything touched with those products.
Stay the "Ai" colours, before wearing (and before discolouring to to others), we recommend you RINSE after you receive it.
1. Make the vinegar-water-solution
The best comparison is 1/5 vinegar for a water.
It might be a cup of vinegar to water of a wash-tub. or a bottle or two bottles of vinegar to 1/3 water of bath-tub.
2. Water the Aizome product in the tub for a night or two nights
3. Rinse it by soap-water (very thin soap water) one time or two.This soap is for remove smell of vinegar.
4. Rinse it by water a couple of times until the discolouring stop.
If you hate the smell of vinegar, we can recommend you rinse it by water without vinegar. In this case, we recommend you to rinse by pure water, not warm , and without soap.
PLEASE BE NOTED THAT BATH-TUB MAY STAINED BY AI-INDIGO. Kitchen bleach might work to remove it, but it might be depends on the material.
