Question: Is there any effect of high water pH in a laundry wash process? Our normal water supply pH is 7-8, but I recently encountered a pH of 9. What might cause this? Is it safe to increase sour to maintain a final linen pH of 6-7, or should I stick to the rule that final pH should be one less than the water supply pH?
Question: What is the concentration of sodium chlorite in bleach purchased at a grocery store?

Question: We have a problem with a clay-like substance in our drain lines and do not know what to do. It leaves a film on our reclaimer and is extremely difficult to clean. We have found main drains are covered with the substance as well. Any ideas?
Question: What is alkali hydrolysis? How can I test for it? Identify it? Prevent it? Resolve it? I know that washload titrations can identify alkali hydro. However, if our titration levels are normal. Can alkali hydrolysis still be affecting our merchandise? Our white tablecloths have become tender at the corners breaking apart (in one direction) and the breakdown of fibers is visible.

A Gruesome Laundry Surprise
PHOENIX, Ariz. — A body in a bin was discovered by employees at a Sodexo commercial laundry facility. The body arrived on a delivery truck from medical facilities in Tucson. Team members who were unloading the bins first noticed blood on the sheets then discovered the body in one of the bins. The man, a transient, had previously slept in the laundry-bag area near the Tucson medical facility. It is believed that the man either died from a medical condition or was suffocated by the plastic bags. The body showed no signs of trauma or foul play.
