Keep your whiteboards clean and go super green! This does several things which are great for the planet; Saves plastic - 1 bottle will last ages as you can simply use the sachets to refill. Saves weight - why should we ship water when you can get it from the tap? No leakages - no more orders damaged by leaks in transit or storage. Simpler to store - sachets can be slipped in a drawer rather than having litres of cleaner stacked up in a storeroom. Carefully formulated for the regular cleaning of all whiteboards large and small including plastic, magnetic and MDF. It's really easy to get started: 1: Unscrew the trigger spray, make sure the sachet is inside and fill the bottle with warm water up to the line indicated 2: Screw on the trigger tightly 3: Shake the bottle to dissolve the sachet 4: Make sure you've erased all dry ink 5: Spray the board and use a microfibre cloth to remove the stains and grime. Show-me recommends cleaning any whiteboard at least once every two weeks to extend the lifespan of the surface. Note: If you have stubborn stains on your board you'll need an alcohol based cleaner like Show-me Magix. When you run out of cleaner you can order replacement sachets in packs of 6.
