When you clean grout, you need to make sure to get rid of all of your grout stains. The best way to go about cleaning it is to spray your walls (or floors) down with your grout cleaner. You want to make sure to allow the grout cleaner at least 15 minutes to soak in. When it soaks in, then you’ll have a better chance of getting rid of the dirt and grime that can be growing on your grout.
After about 15 minutes, you want to use a grout brush to scrub the grout lines and get rid of the discoloration. Sure, you can try to use a sponge or a rag, but a grout brush is going to enable you to penetrate deeper and get the grout clean with less work. You can also try using a steam cleaner. A steam cleaner will allow you to clean without having to do as much scrubbing.
The best grout cleaners to use are those that are nonabrasive. If you try to clean your grout with straight bleach, you are going to do more damage than good. When you use bleach for cleaning, make sure not to use more than a 1 to 10 ratio of bleach to water. Similarly, there are a lot of other cleaners that are pretty strong. Usually, if you can use a cleaner that contains a small amount of bleach, or oxygen bleach, you’re going to have the best results. This is the reason why Kaboom works so well as a grout cleaner. Kaboom is one of the best grout cleaners, because it contains a small amount of oxidizing bleach. It has a cleaning power that you need to deal with tough grout stains, but it doesn’t have too much of it. Once you are completely done cleaning your tile and grout, you’re going to have to choose a good quality grout sealer. The best types of grout sealers that you can use in my opinion, are water-based grout sealers. Don’t buy the cheapest brand, but buy one or two levels up, so you can have a grout sealer that actually works and does what it’s supposed to. Plan on resealing your grout every six months in order to keep from having to clean it as often.
