How to Bleach Designs on Jeans

I saw a show on HGTV where they used bleach to make a design on denim. On the show, they used a solution of equal parts water and bleach, sprayed it over a metal trivet, removed the trivet and then stopped the bleaching action. However, they didn’t say how to stop the bleaching action. How can I use this method without ruining or weakening the material?

I haven’t seen the HGTV show that you mentioned, so I am not familiar with the process they used/recommended.

Here’s part of a response that I wrote for using liquid bleach to make “designer jeans,” which should be similar to the process you are attempting:

• Put some newspapers on the floor and start drawing your favorite designs.
• Let them dry 20-30 minutes, then use a wet paper towel to remove any excess bleach gel.
• Rinse the bleached areas well in the sink to remove any excess bleach. (If you want to stop the reaction, you could add a diluted hydrogen peroxide solution to the area before rinsing. The reaction forms oxygen and should negate both products. Do a couple of rinses to be sure it’s stopped.)
• Dry and repeat on the backside of the jeans.

I would be also be careful using a metal trivet, as these can react with the bleach and deposit some unwanted colors.
