Cleaning grade white vinegar. (not edible)
From Oxford based Sesi Detergent refill, the product is Vegan, Sustainable and part of a circular economy, which means all our supply containers go back to the factory to be reused again and again!
This product has been discontinued by SESI & is no longer available. It is being replaced by a stronger version but as yet we have no date for availability. Citric Acid is a good alterative.
