Vinegar is easy to use, environmentally friendly and safe to use around children. While it is available in several varieties, white distilled vinegar is the best choice for cleaning. It can be used to clean bathrooms, kitchens or any other room in your house. It effectively cleans plastic and will remove film and scum from plastic bottles.
