If you have a clogged drain, you may be wondering if using baking soda and vinegar together will make the problem worse. The answer is that it depends on the type of clog you have. If you have a grease clog, for example, the vinegar can help to break it down. However, if you have a hair clog, the baking soda may just push it further down the drain. In general, it's best to try one method at a time and see what works best for your particular clog.
