What Cleaners Should You Use?
You can decide to clean the brownish color by using all natural products, cleaners, or you can use heavy duty cleaners, or a combination of both. There are many product choices out there that work amazingly well. However, you should be careful when using the cleaners since some of them may release dangerous chemical fumes. In fact, some types of cleaners and bleaches, when mixed together, can create a harmful gas. No matter which cleaner you use, all of these methods will require scrubbing with a sponge or bristle. It is true that none of the cleaners will magically wash the brownish marks away.
