Final answer:
Windex and multi-surface cleaner are not part of a spill kit because they are designed for light cleaning tasks and providing a streak-free shine, not for handling heavy dirt and grease.
Step-by-step explanation:
The items that are NOT part of a spill kit in a typical setting include Windex, a light-duty glass cleaner, and multi-surface cleaner. These products are intended to handle light cleaning tasks and are designed to clean without rinsing, providing a streak-free shine. They are not equipped to handle heavy dirt and grease that are commonly associated with spills that spill kits are designed to tackle. Spill kits commonly include absorbents, like Kitty litter or Spill magic, personal protective equipment, and cleaners or neutralizers for specific substances, but they generally do not include everyday light-duty cleaners.
