I must commend DLI for the fine job they have been during with their on line training. Drycleaners were able to improve their quality and were exposed to handling difficult items such as wedding gown. In these difficult times it becomes more important for drycleaners to improve their expertise and quality. In line with concept I have been designing training sessions on specific topics. The training is designed to last 45 minutes. The training session I did for Wedding Gown Preservation ran like this:

1. We asked the people what they knew about the subject.
2. Gave information on the subject
3. Reviewed questions on the subject

SODIUM PERBORATE AND SODIUM PERCARBONATE FACTS

1. These bleaches are oxidizing agents. They put oxygen in a fabric and stain changing them chemically.
2. Oxidizng agents are more permanent than reducing agents.
3. Sodium perborate is a solid form of hydrogen peroxide and sodium carbonate. It is alkaline in nature.
4. Sodium percarbonate is a solid form of hydrogen peroxide and sodium metaborate.  Sodium percarbonate has an advantage of sodium perborate in the fact that it dissolves easier and works at lower water temperatures better.
5. These bleaches release oxygen slowly and therefore have advantages over either bleaches.
6. Many drycleaners fail to rinse and neutralize these bleaches. If not rinsed and neutralize they will continue to affect the fabric and cause yellowing.
7. They are referred to as color safe bleaches. It is a misnomer. No bleach is completely color safe. They will readily bleed colors 
8. They will whiten fabrics so both pieces of an outfit must be soaked together
9. They will remove last traces of wetside stains, not dryside. This means it is more effective to remove a stain by other methods first and bleaches is the last step.
10. They are also effective as spotting board bleach. It is applied to stain with a lubricant to hold it in place. Use a light feather of steam to heat it and then flush. Then apply an acid and flush again. Remember heat accelerates bleach. Every 18F doubles the chemical action. Remember to test fabrics and color.
11. What to do if a color changes occurs after bleaching and it is not removed with an acid. Use a reducing bleach such as sodium bisulphite or sodium hydrosulphite.
12. These bleaches will affect metallic fabrics and trimming.

HOW TO USE

1. Put two ounces of bleach per gallon of water at 100℉. Add one ounce of neutral lubricant per gallon of water.
2. PH paper can be used to determine the concentration of bleach is adequate.
3. Soak a few hours or overnight.
4. Rinse
5. An acid bath is necessary. Use oxalic acid or acetic acid at the ratio of 2 ounces per gallon of water.
6. Rinse again as a last step

10. What accelerates these bleaches
11. Steps to correct color change on a white gown
12. How do I bleach a gown with a colored trim
13. Can I mix it with water and spray it on a garment
14. What is a sour
15. Why is it important to rinse and sour
16. What is a color-safe bleach
17. Can I use home products containing these bleaches
18. What makes colors run when I use these bleaches

Any person interested in this, I would happy to help you. I can either be part of the training or provide you with the information free of charge.
