Q. Am I putting bleach in my wash?
A. It is quite possible that you are adding bleach in your wash without knowing it. Bleach comes in a number of forms, and have simmilar properties. Many commercialy available laundry detergents contain bleaches without being labeled specificly.
Some pre wash water treatments also contain bleach. You may be doubling up the dose of bleach without ever adding "bleach" to your wash.

Sodium hypochlorite

The properties of Sodium hypochlorite bleach that make it effective for removing stains also result in cumulative damage to organic fibers such as cotton, and the useful lifespan of these materials will be shortened with regular bleaching.
The sodium hydroxide that is also found in many bleaches causes fiber degradation as well. Residual amounts of bleach not rinsed out will continue slowly degrading organic fibers in the presence of humidity.
Sheets and towels that rip easily demonstrate the costs of laundering with bleach. Hot water increases the activity of the bleach, owing to the thermal decomposition of hypochlorite which ultimately generates environmentally-undesirable chlorate.

It is best to consult with your chemical supplier and Laundry system designer for best outcomes.
