Final answer:
Emery boards and nail files, orange sticks/wooden cuticle pushers, and disposable nail buffers must be discarded after use on a nail service client.
Step-by-step explanation:
The nail service products that must be discarded after use on a client are:
- Emery Boards and Nail Files - These are used to shape and smooth the nails and should be disposed of after each use to prevent the transmission of infections.
- Orange Sticks/Wooden Cuticle Pushers - These are used to push back the cuticles and should be discarded after use as they can accumulate bacteria and pathogens.
- Disposable Nail Buffers - These should be used once and then discarded as they can also harbor bacteria and fungi.
Toe Separators on the other hand, can be washed and sanitized after each use and are not required to be discarded.
