How Long Does Quat Sanitizer Last in Spray Bottle? 2 weeks
Quat sanitizer can last in a spray bottle for about two weeks to a month, depending on storage conditions.
Quaternary ammonium sanitizers, commonly known as “quats”, are very stable and can maintain their sanitizing power for a relatively long time.
However, once these sanitizers are diluted and put into a spray bottle, they start to lose their potency.
If the spray bottle is stored in a cool, dark place and the solution is not contaminated during use, it can last for up to a month. After this, it’s recommended to replace the solution to ensure effective sanitization.
When using quat sanitizers in a spray bottle, it’s important to monitor the shelf-life and storage conditions to ensure its effectiveness.
The potency can diminish over time, particularly if the bottle is exposed to heat or sunlight. Regular replacement of the solution every two weeks to a month is good practice for maintaining a high standard of cleanliness and hygiene.
