Can You Use Bleach For Cleaning Grout Between Your Bathroom Tiles?

Grout is the porous material that fills the cracks between your tiles. It comes in various colors, but one thing that is true for all of it is that it is very porous. Of course, it is sealed to help keep out dirt and grime, but over time that sealant breaks down, and dirt starts to get in. Using bleach on your grout will break down that seal even faster.  So you really should avoid using household bleach to clean your bathroom grout.

Will Bleach Damage Bathroom Tiles?

Most bathroom tiles are made out of porous ceramics that are coated with a glaze in firing. Though they are very hardy, porcelain, particularly the use of bleach over long periods, can be damaging to your tiles. Because bleach is caustic, it will eat away at the protective coating of your tiles over time. So it's best not to use a straight bleach product when cleaning your bathroom tiles.

Prepare the Tile And Grout For Cleaning

The first part of this is preparing the grout and the tile for cleaning. Professionals will come in with a large vacuum and suck up any loose grime or debris. Then they will mop to get up any caked up or staining dirt. After that, they will use a steamer to loosen any remaining dirt and grime from corners and around fixtures. This way, all the dirt around the cracks is removed. Finally, they will dry all of the tiles so that the surface is dust-free, clean, and dry.

Use A Professional Grade Cleaner

Just like when you clean it yourself, the professional cleaner will also use a grout cleaning solvent. This might be something like Black Diamond Stone and Grout Cleaner. This type of cleaning solution is acid-free and won't cause damage to your tiles or your grout. This one is also available to homeowners if you want to try the professional route yourself.

Reseal The Grout

The final step after a professional cleaning is to reseal the grout. Without resealing, grout will tend to soak in more dirt and grime because it's so porous. Then all that hard work will be lost because they'll look stained again. That's why it's so important to take this final step of resealing with a good sealer.
