When you need a little more control over what you are cleaning, painting or applying glue to, a foam brush is an economical option. They are easy to clean up, light weight and can be used for a lot of different things around the house. If you want to use these for cleaning they are a great choice over using a regular sponge to clean wood casings around windows. I use them dry to remove dust but have also used them after I have sprayed the finished wood sections of the windows. Because this is a sponge it gets into all of the bevels of the wood without having to wad up a paper towel or rag. You can get these in a variety of sizes; the thinner ones are great for applying glue or an adhesive for doing collage work but you can also use them for painting signs. You have a lot of control over where the paint is going but you have to avoid over saturating it or you will end up with the paint dripping out of the foam. These allow for quicker coverage to larger areas but if you are painting interior rooms they are one of the best products for working in small areas like around door frames, window ledges and near baseboards. One of the things that I absolutely love about this is that you can trim them; if you have one with a three inch wide head you can use scissors to cut a little bit off. I have done that in the past when I was applying border trim and needed a way to apply water to the back of the paper without getting water everywhere.
