Our Kitchee 5 Piece Refillable Amber Glass Spray Bottle and Trigger come with a high-quality chemical-resistant Canyon trigger head (with tube filter) and are well suited to making up your own cleaning sprays with essential oils for use around the home. The dark amber glass bottle helps protect the contents from damaging UV light, and the trigger spray head features an adjustable head for off / mist / stream sprays. The product range provides suitability for multi-purpose cleaners, glass cleaners, bathroom cleaners, starch products, disinfectants, insecticides and many others! We do not recommend using Castile soap with glass trigger spray bottles, as the oily ingredients found in Castile soap can cause the triggers to come loose from the glass bottle.
