Why Saline Is the Standard
Saline solution (0.9% salt water) is the medical standard for wound irrigation. Normal saline is isotonic with body fluids and effectively cleanses wounds without damaging tissue. It flushes dirt, bacteria, and debris from cuts and scrapes. Hospitals and first aid kits rely on sterile saline for this reason.
Making Saline at Home
For minor wounds, dissolve 1/2 teaspoon of non-iodized salt in 1 cup (8 oz) of boiled water that has cooled to room temperature. Use within 24 hours. Pour or squirt gently across the wound. Do not use homemade saline on deep punctures, animal bites, or heavily contaminated injuries. Those need professional care.
Basic Wound Care Steps
Wash your hands first. Rinse the wound with saline or clean running water. Apply gentle pressure with a clean cloth to stop bleeding. Cover with a sterile bandage. Change dressings daily or when wet. Watch for redness, warmth, pus, or fever. Consult a clinician if signs of infection appear.
What Not to Do
Do not pour undiluted salt directly onto an open wound. High salt concentration damages tissue. Avoid hydrogen peroxide or alcohol on healing wounds unless a clinician advises it. Do not use Epsom salt for wound irrigation.
