Vashe Wound Solution is a hypochlorous acid-based cleanser used to irrigate, moisten, and debride acute and chronic wounds. You apply it by soaking the wound directly, irrigating with gentle pressure, or saturating gauze to use as a wet dressing. The method you choose depends on the wound type, location, and your care provider’s instructions.
What Vashe Actually Does
Vashe contains a very low concentration of hypochlorous acid (no more than 0.033%), a substance your own white blood cells naturally produce to fight infection. It works by disrupting the proteins in bacterial cell membranes, causing bacteria to lose control of their internal environment and die. Unlike harsher antiseptics like hydrogen peroxide or iodine, hypochlorous acid at this concentration does not damage healthy tissue, making it safe for direct wound contact.
What sets Vashe apart from simple saline rinses is its ability to break down biofilms, the slimy protective layers that bacteria form over wound surfaces. In lab testing, saline and surfactant-based cleansers achieved roughly a 1.7 to 1.8 log reduction in bacterial viability within biofilms. Vashe achieved complete inactivation of the microbes, equivalent to greater than a 4.5 log reduction. That’s the difference between knocking bacteria down modestly and eliminating them entirely from the biofilm structure.
Three Ways to Apply Vashe
Soaking
For wounds that can be submerged or covered with saturated material, soaking is the most effective method. Pour Vashe directly into the wound bed or saturate gauze pads and lay them over the wound surface. The lab data showing maximum biofilm destruction used a 10-minute soak time, which is a reasonable target for thorough cleansing. Keep the wound moist with the solution for the full duration. You can reapply fresh solution to the gauze if it begins to dry out during the soak.
Irrigation
For deeper wounds, tunneling wounds, or areas that are hard to soak, irrigating with Vashe works well. Use a syringe (typically 30 to 60 mL) to gently flush the wound bed. The goal is to deliver enough pressure to dislodge debris and bacteria without damaging new tissue. A pressure around 8 to 12 PSI, which a syringe with an appropriate tip naturally produces, is the general clinical target. Flush until the solution runs clear from the wound.
Moistened Dressings
Vashe can also be used to saturate gauze or other compatible primary dressings that stay in contact with the wound between dressing changes. This keeps the wound environment moist and maintains antimicrobial activity over a longer period. Soak your gauze or wound contact layer thoroughly with Vashe before placing it on the wound, then cover with a secondary dressing as directed by your care provider.
Step-by-Step Application
Start by washing your hands and gathering your supplies: Vashe solution, clean gauze or irrigation syringe, gloves, and your wound dressing materials. Remove the old dressing carefully and dispose of it.
If you are soaking, pour enough Vashe to fully cover the wound surface or saturate several layers of gauze. Place the wet gauze over the wound and let it sit for up to 10 minutes. If you are irrigating, draw the solution into your syringe and flush the wound gently, allowing the fluid to drain into a basin or absorbent pad beneath the wound. Use enough solution to thoroughly rinse the entire wound bed.
After soaking or irrigating, gently pat the surrounding skin dry. You do not need to rinse Vashe off with saline or water afterward. Apply your prescribed wound dressing directly over the cleaned wound.
Storage and Shelf Life
Vashe remains stable whether the bottle is opened or unopened until the expiration date printed on the back of the bottle. Unlike some wound care products that degrade quickly once exposed to air, you can use the same bottle across multiple dressing changes without worrying about reduced effectiveness. The solution is designated for single-client use, meaning one bottle should be used for one person only. Store it at room temperature, away from direct sunlight.
What Vashe Is Safe to Use On
Vashe is cleared for use on a wide range of wound types: surgical incisions, pressure injuries, diabetic foot ulcers, venous leg ulcers, first- and second-degree burns, skin grafts, and abrasions. It is non-cytotoxic, meaning it does not harm the living cells your body needs to rebuild tissue. There is no sting or burning sensation on application for most people, which makes it especially useful for painful wounds or sensitive areas.
The solution is also safe to use on wounds that are already showing signs of infection, though it is a cleanser rather than a treatment for established infection. If your wound has spreading redness, increasing pain, warmth, or drainage with odor, wound cleansing alone is not sufficient.
Tips for Getting the Most Out of Vashe
Use enough solution. A common mistake is being too conservative with the volume. Effective cleansing requires the wound to be fully bathed in the solution, not just lightly dampened. For irrigation, plan on using at least 100 to 200 mL per session for a moderately sized wound.
Allow adequate contact time. A quick rinse removes surface debris but does not address biofilm. If biofilm is a concern, which it is in most chronic wounds, letting the solution sit on the wound for several minutes makes a significant difference in bacterial kill rates.
Do not mix Vashe with other wound care products in the same step. Apply it as a standalone cleansing step before adding any topical ointments, gels, or medicated dressings. Mixing products can alter the pH and reduce the effectiveness of the hypochlorous acid.
Keep the bottle closed when not in use. While the solution is stable through its expiration date, minimizing contamination of the bottle opening is standard wound care hygiene. Pour the solution out rather than dipping gauze into the bottle.
