Tile and Grout Cleaning Tips
By Troy Cantini
Ceramic tiles are typically easy to clean but the grout between the tiles is usually much more difficult to clean. Ceramic tiles are dense non porous products that will not typically be damaged by most tile cleaning products or scrub pads. Therefore you can use aggressive tile cleaning products combined with aggressive scour pads to scrub the tiles and grout without damaging the tiles.
The ability to use alkaline and acidic tile cleaning products makes ceramic tiles easy to clean and maintain. Also most ceramic tiles are dense tiles with high coefficient of friction (cof) values so they are not easily scratched or scuffed with aggressive scrub pads or scrub brushes. You should still not use any type of metal based pads such as Brillo pads that could potentially scratch the tiles.
Generally the dirt, grease and grime on ceramic tile floors is most easily cleaned with an alkaline tile and grout cleaning product. Alkaline tile cleaning products will react with the dirt, grease and grime and suspend these contaminates. The suspended dirt, grease and grime can then be easily extracted and rinsed away.
You should scrub the ceramic tiles and grout until you are confident that all of the dirt, grease and grime have been loosened and dissolved. Aggressive scrub pads will work much more effectively than scrub brushes for cleaning up the grout lines. A shop vac can then be used to extract the dirty cleaning solution. If you do not have a shop vac then you can use a mop and bucket to extract the dirt and excess cleaning solution.
Cleaning the ceramic tile surfaces is usually not too difficult but getting the grout lines clean is usually much more difficult. You may notice that even after you have cleaning the ceramic tiles with the alkaline cleaning solution that the grout lines still may look dirty or have some remaining stains on them. A mild acidic tile and grout cleaner works great for getting the grout lines to look like new again. Ceramic and porcelain tiles will not be damaged with acidic based tile cleaners but you can not use acidic cleaners on stone tiles. Acidic tile cleaning products are especially effective on lighter colored grout lines to remove the stubborn stains that are embedded deep within the grout lines.
You can apply the acidic tile cleaner to the tile and grout lines just like you did with the alkaline tile cleaner. You should see the grout lines "FIZZ" when the acidic cleaner reacts with the top layer of dirty grout. A type of micro abrasion cleaning effect will take place as the acidic cleaning solution removes the top layer of dirty grout. Some light scrubbing of the grout lines may be necessary with the acidic cleaning solution to remove extremely stubborn stains from the grout.
You should thoroughly rinse and dry the tile floor and grout lines after they have been cleaned. You will want to ensure that the grout lines are totally dry before sealing them with any type of sealer. In some situations with extremely dirty and damaged grout it may truly be impossible to get the grout lines looking totally clean and stain free. In these cases painting the grout with a grout colorant can restore the original look and color of the grout. If you do decide to paint the grout you will still need to thoroughly clean the tile and grout before applying the grout colorant to the grout.
After deep cleaning the ceramic tile floor you should always seal the porous grout with a clear impregnating sealer. Strong alkaline and acidic tile cleaning products will break down the sealers that were previously applied. Sealing the ceramic tiles themselves is not needed because the ceramic tiles are too dense and non porous to absorb any kind of tile and grout sealer.
For normal every day cleaning a non aggressive pH neutral cleaning product should be used. pH neutral tile cleaning products can easily be used to mop away and rinse the dirt and grime from the tiles without having to do excessive rinsing and extracting of the dirty cleaning solution. Only about 2-4 ounces of the pH neutral cleaning solution is required in a gallon of hot water to clean the ceramic tiles on an everyday basis. PH neutral cleaners also will not break down the sealers in the grout lines and they will not damage any grout colorants that have been applied to the grout lines.
For large areas of tile and grout you should consider hiring a professional tile cleaning and restoration contractor to steam clean your tile and grout. Professional steam cleaning machines are able to steam clean large areas of tile and grout in a relatively short period of time. Additionally professional steam cleaning machines will extract all the dirty cleaning solutions off of your tiles and grout and more effectively sanitize your tile and grout.
