It’s easy to use…Simply Drop, Add Water, Shake & Clean Spotlessly. Place one EcoDrop into a clean 750ml spray bottle and fill to the top with water. Screw on the spray-top and shake. Leave to stand until the drop is fully dissolved. Spray from a distance of 20cm and leave to stand for 2 minutes then wipe down with a clean, damp cloth. If you are reusing an old spray bottle, give it a good rinse before use and apply the stickers included in the pack to the bottle.
