What is the shelf life No Rinse Sanitiser Super Concentrate.  How often does a bottle need to be made up ready to use in a childcare kitchen

Regards Kath

Our Earth Renewable super concentrate product has a 2 year expiry date which is shown on the white batch sticker on the side of the bottle.  When a ready to use batch is made up in the spray bottle it is effective for several weeks.  This product is quaternary ammonium unlike a bleach which would be disposed of at the end of the day ( 24 hours).
