Simply pop one EcoDrop into a clean 750ml spray bottle and fill to the top with water. Screw the lid on, shake and leave until the drop is completely dissolved. To use, spritz bathroom surfaces from a 20cm distance, leave it for a couple of minutes and then wipe away with a clean, damp cloth. If you’re reusing an old spray bottle, don’t forget to give it a rinse out first and affix the stickers included with your EcoDrops.
