ONA Gel Odour Neutraliser | 1 L and 4 L – 7 Fragrances

ONA Gel odour neutraliser is a slow-release gel for managing persistent ambient odours in indoor garden utility rooms, workshops and other well-ventilated spaces. The manufacturer's gel suspension allows the ONA formula to disperse gradually as the exposed surface evaporates, making it a simple alternative to regular spray applications.

Choose the right ONA Gel size

• 1 L jar: convenient for smaller rooms and targeted placement.
• 4 L tub: for extended or larger-area applications, subject to the current dispenser compatibility guidance.

Fragrance choices

Available in Apple Crumble, Fresh Linen, Fruit Fusion, Lemongrass, Polar Crystal, PRO and Tropics. Not every fragrance is listed in every size; the available combinations shown above correspond to individual existing SteelRoots Sage stock records.

How to use ONA Gel

Open the container in a location with appropriate ventilation and allow controlled evaporation. Increasing the exposed surface area or using a manufacturer-compatible ONA dispenser may accelerate distribution. Do not add to hydroponic nutrient tanks or spray onto foliage, and always follow the current product-label safety instructions. Keep out of reach of children and pets.
