Question 1

Which type of stain requires cold water treatment rather than hot water to prevent it from setting?

Accepted Answer

Protein-based stains such as blood or egg

Answer

Hot water coagulates proteins and permanently sets blood and similar stains, so cold water must be used first.

Question 2

What does the term 'rewash rate' measure in a hotel laundry operation?

Accepted Answer

The percentage of linen items needing a second wash cycle due to inadequate cleaning

Answer

Rewash rate tracks the percentage of items that fail quality inspection and must be laundered again, reflecting wash formula effectiveness.

Which regulatory agency standard must commercial laundries meet regarding water temperature for sanitizing healthcare or food-service linens?
