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 you can choose your own glass bottle to re-fill and that cuts down on A LOT of waste and plastic bottles! It really is the perfect solution (pun intended!) to plastic free cleaning! ABOUT THE GLASS & MIRROR SURFACE CLEANER For a smear free clean of windows and mirrors in the home you need a quality product!Simply spray a small amount onto the surface and wipe with a clean cloth, then use a second dry microfibre cloth for a streak free sparkle!
