Tips for summer use of Hypochlorous acid spray

As we head into the warmer months, many of us are spending more time outdoors, and leaning a little more  on skin-calming essentials . At SpraySafe, we’re proud to offer Re:Juve; a naturally powerful bacteria fighting hypochlorous acid (HOCl) water solution. Bottled fresh in NZ to keep the formula as active as possible for longer. 

But here’s one thing to remember as temperatures climb: HOCI is temperature-sensitive, and summer heat can affect its stability and effectiveness. With a few simple storage habits, you can keep your mist performing at its best all season long. 

Why Temperature Matters

Hypochlorous acid is a remarkable, naturally occurring molecule recognised for protecting skin prone to irritation, breakouts, eczema, and environmental stressors. But its effectiveness relies on a stable pH. 

When exposed to temperatures above 25°C, the pH begins to neutralise, meaning the HOCl gradually loses its ability to calm the skin and keep bacteria in check.  

The Hidden Summer Risk

Inside a parked car, or in direct sunlight temperatures can reach 40°C or higher, even on mild days. At this temperature, HOCl effectiveness diminishes and the product loses much of its natural antimicrobial power and skin-calming effectiveness.

A good  rule of thumb: “If it feels too hot for you, it’s too hot for your HOCl”

Our Bottle System Helps You Care for Your Product

We’ve designed a practical, summer-friendly system to help you get the best performance from your purchase:

This system lets  you store the bulk of your product cool while keeping just what you need on hand.

Summer Storage Tips for Maximum Freshness

Here’s how to protect your HOCI mists during the warmer months: 

1. Keep your 320ml refill bottle in the fridge

This  keeps HOCl in its optimum temperature range and can maintain stability for up to 12 months (just don’t let it freeze).

2. Decant into your smaller bottles

Top up  your 30ml or 140ml bottles as needed. Using  a cool, stable source means your daily mist is always at peak performance.

3. Avoid leaving any bottle in the car

Even during short errands, in-car temperatures can spike dramatically impacting the effectiveness of the solution.

4. Keep small bottles out of direct sunlight

Store them in a handbag, backpack, tool bag, bathroom cupboard, or any shaded space.

5. Air-conditioned environments are best

At home, at work, or in the car while you’re driving, controlled temperatures help maintain stability ensuring the spray performs at its best..
