The answer depends on what you're scrubbing! The recommended scrubbing time varies greatly depending on the context.
Body Scrubbing
For a body scrub, you should scrub your skin gently for no longer than 30 seconds. Source Use a small amount of scrub and circular motions. Over-scrubbing can irritate your skin.
- Key takeaway: Keep it brief – 30 seconds maximum.
Facial Exfoliation
The time you leave an exfoliant on your face depends on the type of product. Chemical exfoliants can be left on overnight or washed off after 10 minutes, depending on the product's instructions. Source Always follow the product instructions.
- Key takeaway: Check product instructions; times vary widely.
Data Scrubbing (RAID/Storage)
Data scrubbing, for RAID systems or storage arrays, is a different process entirely. The time required for a scrub can vary significantly:
-
Small arrays: May take hours.
-
Large arrays: Can take hours or days. Source
-
Frequency: This depends on your system, data importance and drive type. Some suggest weekly scrubs, while others recommend every few months, with some users choosing a frequency based on the percentage of the array that can be checked per week.
