According to the Association of Professional Piercers (APP), homemade saline solutions are no longer a recommended aftercare practice due to the high risks involved. So, is it safe to use homemade saline solution for piercings, or is it a dangerous shortcut to avoid?

Quick Summary

Using homemade saline solution for piercings is not safe because achieving the correct sterile, isotonic balance is nearly impossible at home, leading to potential bacterial contamination, irritation, and delayed healing.

Key Points

Risky Practice: Using homemade saline solution is highly discouraged by experts due to the dangers of bacterial contamination and inaccurate salt ratios [2, 3].
Potential for Infection: Tap water and non-sterile containers can introduce harmful bacteria to a fresh wound, leading to serious infections [3].
Incorrect Concentration: An improperly mixed solution can be too strong, causing 'salt burns' that irritate the wound and delay the healing process [2].
Stick to Sterile Wound Wash: The safest and most effective method is to use a store-bought, pre-packaged sterile saline wound wash specifically for wounds [2, 3].
Avoid Harsh Chemicals: Never use rubbing alcohol, hydrogen peroxide, or other additives on a new piercing, as they can cause severe tissue damage [2].
Follow Professional Advice: Always follow the aftercare instructions provided by a professional piercer to ensure a healthy healing process [2].

The Hidden Dangers of DIY Saline

When a new piercing is created, it is essentially an open wound. Proper aftercare is crucial for a smooth and healthy healing process, and the standard recommendation for decades has been a simple saline wash. For a long time, many assumed a mix of salt and water from the kitchen was a perfectly acceptable substitute for commercial products. However, this assumption is dangerously flawed, and professional piercers and medical experts now advise strongly against it.

Why Homemade Isn't Sterile

Sterility is the most significant factor. Commercial sterile saline wound wash is manufactured in a controlled environment and comes in a sealed, sterile container. Everything, from the water to the salt and the bottle itself, is guaranteed to be free of contaminants. In contrast, your home kitchen is a breeding ground for bacteria. Your water, salt, and mixing vessel are all potential sources of harmful microorganisms that can easily be introduced into a fresh, vulnerable wound, leading to serious infection.

The Incorrect Salt-to-Water Ratio

Another major risk is getting the salt concentration wrong. A proper saline solution, known as an isotonic solution, has a specific salt concentration that mimics the body's natural fluids [1, 2]. This delicate balance is vital for creating an ideal healing environment. At home, attempting to measure and mix can result in an inconsistent solution. The slightest variation can make the solution either too weak or, more commonly, too strong. An overly concentrated solution can draw moisture out of the healing tissue, causing severe irritation, dryness, and a phenomenon known as 'salt burn.' This damage can significantly delay healing or lead to more serious complications.

Why Professional Sterile Saline is Superior

In contrast to the risks associated with DIY mixtures, professional sterile saline wound wash offers a clear path to safe and effective piercing aftercare. It eliminates all the guesswork and potential hazards, providing peace of mind during the crucial healing period.

Guaranteed Sterility

Factory-sealed sterile saline wound wash is guaranteed to be sterile right out of the package. Products are often packaged using bag-on-valve technology, which keeps the solution sterile throughout its use by preventing outside air from mixing with the contents. This is a level of purity that cannot be replicated at home.

Precise Salt Concentration

Commercial saline is formulated to the exact isotonic balance needed for wound care [1, 2]. There is no risk of mixing an irritatingly strong or ineffective weak solution. This consistency provides the best possible environment for a new piercing to heal without stress or complication.

Best Practices for Piercing Aftercare

Beyond simply choosing the right product, a successful healing process depends on a holistic approach to aftercare. By following these guidelines, you can give your new piercing the best chance to heal cleanly and without issue [2, 3].

Wash Your Hands: Before cleaning or touching your piercing, wash your hands thoroughly with antibacterial soap. This is the single most important step to prevent introducing bacteria [2].
Clean Gently: Use a sterile wound wash saline spray, applying it to a clean paper towel or gauze and gently dabbing the piercing. Never use cotton balls, as the fibers can get caught in the jewelry [2].
Don't Twist or Turn: Contrary to old advice, twisting or rotating your jewelry is not helpful. It can damage new tissue and delay healing. Leave the jewelry alone [2].
Avoid Submerging: During the initial healing period, avoid swimming in pools, hot tubs, lakes, or oceans, as they contain high levels of bacteria [2].
Pat Dry: After cleaning, gently pat the area dry with a fresh paper towel. Do not use cloth towels, which can harbor bacteria [2].
Leave the Jewelry in: Never remove your jewelry during the healing phase, as the piercing can close surprisingly quickly [2].

A Comparison of Saline Solutions


Feature	Homemade Saline	Professional Sterile Saline
Sterility	Non-sterile, high risk of bacterial contamination.	Guaranteed sterile, manufactured in a controlled environment.
Salt Concentration	Inconsistent, often too strong or too weak.	Precise, isotonic concentration.
Ingredients	Varies (table salt, sea salt, tap water).	Purified water and sodium chloride only.
Healing Outcome	Higher risk of irritation, dryness, and infection.	Promotes optimal, irritation-free healing.
Recommended Use	Not recommended by professional piercers or medical experts.	The industry standard for safe piercing aftercare.

Conclusion: Prioritize Safety Over Savings

While the thought of saving money by mixing your own saline solution may be tempting, the potential risks to your health and the healing of your piercing far outweigh the minimal cost savings. A trip to the emergency room for a piercing infection will cost far more than a bottle of sterile wound wash. For the safest and most effective aftercare, always opt for a pre-packaged, sterile saline solution designed for wound care. Your piercer will thank you, and your new piercing will heal as beautifully as you intended.

Alternatives to Homemade Saline

If you find yourself without sterile wound wash, the best temporary alternative is a gentle, fragrance-free soap and clean, running water [2]. This should not be a long-term solution, but it can be used for a day or two until you can purchase the correct sterile saline product. Remember to rinse thoroughly to remove all soap residue. Never use hydrogen peroxide, rubbing alcohol, or other harsh chemicals, as these will damage your healing tissue [2].

What to Do If You've Already Used Homemade Saline

If you have already been using a homemade solution, switch immediately to a sterile, packaged saline wound wash. Monitor your piercing closely for any signs of irritation or infection, such as prolonged redness, swelling, pus, or excessive pain. If symptoms appear, contact your piercer or a healthcare professional immediately. It is always better to be safe and seek professional advice than to risk a serious complication.

Frequently Asked Questions

No, it is not recommended by professional piercers and medical experts. The inability to guarantee sterility and the difficulty in achieving the correct salt concentration make it a risky practice that can lead to irritation or infection [2, 3].

If your homemade solution is too salty (hypertonic), it can draw moisture out of the delicate healing tissue. This can cause dryness, redness, and severe irritation, often referred to as a 'salt burn,' which significantly delays the healing process [2].

Table salt often contains additives like iodine and anti-caking agents that are not suitable for wound care. These chemicals can irritate and damage healing tissue. Only non-iodized salt should ever be used, but even then, sterility and concentration remain serious issues [2].

The best alternative is a store-bought, packaged sterile saline wound wash. These are readily available in the first-aid section of most drugstores and are specifically formulated for wound cleaning with the correct isotonic balance and guaranteed sterility [2, 3].

No, you should never use contact lens saline on a piercing. Contact lens solutions often contain preservatives and other additives that are not safe for an open wound and can cause severe irritation or allergic reactions [2].

Bacteria can be introduced from unboiled tap water, your hands, a non-sterile mixing container, or the salt itself. Unlike a controlled manufacturing process, a home kitchen environment makes it impossible to prevent microscopic contamination, which poses a serious risk to a new piercing [3].

Yes, using an improperly mixed or contaminated homemade solution can absolutely delay healing. Irritation from an incorrect salt concentration and the presence of bacteria from a non-sterile solution both interfere with the body's natural healing process, potentially prolonging the recovery period or causing complications [2, 3].
