Why we use Saline vs. Sterile Water vs. Tap Water vs Seawater- Not all water is equal

In this episode Dr. G explains why 0.9% sterile saline is the preferred when using to cleanse   for diabetic foot ulcers, diving into osmosis, isotonicity, and how saline preserves cell function while avoiding tissue damage. Why we use saline, why tap water is controversial and what alternatives really do.  Dr G also covers the risks of seawater and tap water (including dangerous bacteria like Vibrio vulnificus and piped biofilms), when advanced cleansers such as hypochlorous acid are needed, and practical takeaways: avoid ocean and non-sterile water, use isotonic sterile saline or recommended wound cleansers.
