Bicarbonate Of Soda There really isn't anything that bicarbonate of soda can't do. Like, seriously. From deodorising smells to cleaning grout, one box of bicarbonate of soda can go a long way. It also makes the best oven cleaner (I know by firsthand experience), and when mixed with water, it can seriously lift grime from just about anywhere. Image Source: Unsplash / Jonathan Pielmayer
