This idea is genius! You work so hard to get your fridge all clean and then it is dirty a week later. This is not the cheapest method but I think it is so worth it. You lay it down and when it is dirty off it comes and your fridge is still clean. This is especially great for sticky stuff that spills and is so hard to get off. It does take some time to get everything covered and you need to buy saran wrap or press n seal and little round stickers to get it to stick down. Other than that it is easy and very effective.
