You’re standing in your bathroom at 11:00 PM. Your new helix or nostril piercing is feeling a bit crusty, maybe a little tender, and you realize you’ve run out of that tiny spray bottle the piercer sold you. You look in the cabinet. There it is. A giant bottle of contact lens solution. It’s saline, right? It goes in your eyes, so it must be gentle.
Stop right there.
Honestly, the logic makes sense on the surface. If you can pour a liquid into your eyeball without screaming in pain, surely it’s safe for a small hole in your ear. But the reality is that using contact lens solution to clean piercings is one of those "hacks" that can actually stall your healing process or, worse, trigger a nasty reaction. It isn't just about the salt. It is about everything else they put in that bottle to keep your plastic lenses from growing bacteria.
The Chemistry Problem You Didn't See Coming
Most people think "saline is saline." That is a mistake.
When a professional piercer tells you to use saline, they are specifically talking about 0.9% sodium chloride dissolved in purified water. This is often called "Isotonic Saline." It matches the salt concentration of your blood and body tissues. It’s neutral. It doesn't sting because your body recognizes it as its own.
Contact lens solution, however, is a complex chemical cocktail. It’s designed to break down proteins, dissolve lipids, and kill microorganisms that might hitch a ride on a silicone hydrogel lens. To do that, manufacturers add preservatives and buffers.
Take a look at the back of a bottle of Opti-Free or Renu. You’ll see ingredients like Polyaminopropyl Biguanide, Chlorhexidine, or EDTA. These chemicals are fantastic for disinfecting a contact lens. They are absolutely terrible for an open wound. When you have a fresh piercing, you essentially have a "controlled" puncture wound. Your body is trying to grow new skin cells—called epithelial cells—to line that tunnel (the fistula).
Those preservatives? They don't just kill bacteria. They can be cytotoxic, meaning they can damage or kill those brand-new skin cells you’re trying to grow. If you keep hitting your piercing with harsh preservatives, you're basically nuking the construction site every single day.
Hydrogen Peroxide and Other Old School Myths
While we are on the subject of bathroom cabinet alternatives, let's talk about the big ones: Alcohol and Hydrogen Peroxide.
A lot of us grew up with parents who doused every scrape in peroxide. We loved the bubbles. We thought the fizzing meant it was working. It was, but not in the way you want for a piercing. Peroxide is an oxidative agent. It kills bacteria, but it also destroys healthy tissue and fibroblasts.
Using alcohol or peroxide on a piercing is like trying to put out a small campfire with a literal grenade. You'll put the fire out, but you won't have a campsite left. This leads to excessive scarring, those annoying "piercing bumps" (granulomas or irritation bumps), and a healing time that stretches from months into a year.
What Actually Happens to Your Skin?
When you use contact lens solution to clean piercings, you might notice the skin around the jewelry getting flaky or red. This isn't usually an infection. It's Contact Dermatitis.
Your skin is an incredible barrier, but it’s sensitive to prolonged exposure to preservatives. Many people develop a localized allergy to the ingredients in multi-purpose contact solutions. If the skin around your piercing starts to look like parchment paper or feels itchy, that’s your body telling you to stop the chemistry experiment.
Furthermore, many contact solutions contain "buffering agents" like boric acid or sodium borate to maintain a specific pH level for the eye. The pH of your eye is around 7.0 to 7.4. Your skin, however, is naturally more acidic, usually sitting between 4.7 and 5.7. Constantly shifting that pH with eye-specific buffers can disrupt the "acid mantle" of your skin, making it easier for actual pathogenic bacteria to take hold. It is a weird paradox: by trying to clean it with a disinfectant, you might be making it easier to get infected.
The Correct Way: Sterile Saline Is King
If you want your piercing to heal, you need a product that does one thing: irrigation.
You aren't trying to "sterilize" the hole. You are trying to wash away "crusties" (dried lymph and blood) and debris without irritating the tissue. The gold standard in the piercing industry—recommended by the Association of Professional Piercers (APP)—is a pressurized saline spray.
Brands like NeilMed Piercing Aftercare or Sterile Saline Wound Wash (found in the first-aid aisle) are what you need. These are different from contact solution for two major reasons:
- Ingredients: They only contain water and 0.9% sodium chloride. No preservatives.
- Packaging: They are in a pressurized can with a one-way valve.
This second point is huge. Once you open a bottle of contact lens solution, bacteria can get inside the tip. Every time you use it, you're potentially introducing old bacteria back onto your wound. A pressurized saline mist stays sterile from the first spray to the last.

Why the "Home Mix" is Also Risky
"Can't I just mix sea salt and warm water in a mug?"
You could. People have for decades. But honestly? You probably shouldn't.
The "sea salt soak" is becoming a bit of a relic in the professional piercing world. Why? Because humans are bad at measuring things. If you put too much salt in your water, you create a hypertonic solution. Instead of soothing the piercing, a salty-heavy mixture will pull moisture out of the cells via osmosis. It dries the wound out completely.
Plus, your kitchen isn't a cleanroom. Your measuring spoons have been in the drawer, your tap water might have minerals or chlorine, and that "sea salt" might have anti-caking agents or iodine.
When Should You See a Doctor?
Sometimes, people reach for contact lens solution because they think their piercing is infected and they want something "stronger."
If your piercing is actually infected, saline—even the good stuff—won't fix it. You need to know the signs of a real problem versus simple irritation:
- Heat: The area feels hot to the touch.
- Swelling: The swelling is moving away from the piercing site and spreading.
- Discharge: Thick, green, or foul-smelling pus (not the thin, clear/pale yellow lymph fluid that is normal).
- Red Streaks: Any red lines radiating from the piercing. This is an emergency.
If you see these, don't go to the drug store for contact solution. Go to a doctor for antibiotics. And whatever you do, do not take the jewelry out. If you pull the jewelry, the hole can close up and trap the infection inside, leading to an abscess.
A Better Routine for Lazy (or Busy) People
If you've been using contact lens solution to clean piercings because it's convenient, let's simplify a better routine.
- Leave it alone. This is the LITHA method (Leave It The Hell Alone). Your body knows how to heal wounds. It's been doing it since you were a toddler.
- Rinse in the shower. Let warm water run over the piercing for a minute. This softens the crusties so they fall off naturally.
- Spray and go. Use a proper sterile saline mist twice a day. Spray it on, let it sit for a second, and then—this is the part everyone forgets—dry it.
- Dryness is key. Bacteria love moisture. Use a hair dryer on the "cool" setting or a piece of sterile gauze to pat the area dry. Do not use a fuzzy towel; the loops can snag the jewelry and rip your soul out of your body.
The Cost of the "Shortcut"
A bottle of generic contact solution costs maybe $6. A can of proper piercing saline costs about $10.

For that $4 difference, you avoid potential chemical burns, allergic reactions, and the dreaded "piercing bump" that takes months to go away. It’s a classic case of "penny wise, pound foolish." If you've spent $60 to $100 on a professional piercing and high-quality titanium jewelry, don't cheap out on the $10 spray that ensures it actually stays in your body.
Moving Forward With Your Piercing Care
If you have already been using contact lens solution, don't panic. You haven't ruined your ear forever. Just stop today.
Switch to a dedicated saline wash that lists only two ingredients: USP Grade Water and 0.9% Sodium Chloride. Check the first-aid section of any pharmacy for "Wound Wash"—just make sure it doesn't say "plus pain reliever" or "plus antiseptic."
Keep your hands off the jewelry. No twisting, no turning, and definitely no picking at the scabs with your fingernails. If the piercing feels excessively dry or irritated after stopping the contact solution, give it a few days of "just water" rinses to let the skin's natural pH rebalance itself. Your piercing will thank you by actually healing, rather than being a constant source of redness and frustration.
