A common mistake people make when cleaning their home is to use the same broom inside of the home as they do outside. This is bad because it can bring in contaminants from the outside into your home. This is especially problematic if a person has allergies or anything. This is why getting a special garden brush for outside if best. Not only will a person be able to still sweep things up outside, but it will also keep that dirt and material from entering the home. Another nice thing about a garden brush is that you can get special ones that allow you to get into cracks in the pavement or walking stones. In short, you want to keep the outside from coming indoors, so sweeping outdoors with a special brush is best, while keeping your inside broom clean and indoors.
