These INCREDIBLE water soluble sachets are the best cleaning solution I've come across when it comes to shipping online (as we aren't all in close proximity to a refill shop). These sachets are PLASTIC FREE, light and can be stored with minimal space in your home until you're ready for a top up! Plus this set comes with a 1x glass bottle to re-fill to help you cut down A LOT of waste and plastic bottles! It really is the perfect solution (pun intended!) to plastic free cleaning! ABOUT THE OVEN CLEANER With a powerful combination of cleaning agents this Oven Cleaner has been designed for those tough, burnt on fats.With a few sprays and just minutes to work you'll significantly reduce the amount of elbow-grease required to clean your oven. And with this low odour, low vapour formula you won't have issues with breathing in chemicals either.
