Clean your messy microwave quickly and naturally with just a lemon and water. It takes only six easy steps, and your microwave will look as good as new — and smell lemony fresh too! As this video demonstrates, simply slice the lemon and squeeze the juice into a bowl of water. Put the remainder of the lemon in the bowl, and microwave it to create lemon-infused steam. Let the steam sit and then just wipe away the crumbs and residue — your microwave is set to get back to cooking!
