How to steam clean shower tile grout

Tools needed

A steam cleaner or a pressure washer is the most effective tool for tackling shower grout. Additionally, a sturdy nylon brush of any size will help you work through the dirt and caked-on soap scum from between the grout lines. Lastly, a mixed solution of vinegar and water will help break down oil and grease stains on the surface of your shower tiles.


Prepare your steam cleaner

Fill your steam cleaner with hot water to ensure that it reaches the desired steam temperature (usually around 220 degrees). If you are using a pressure washer, fill it with hot water as well. Make sure both devices are filled before continuing. Tip: Make sure that the water is boiling. If it’s not, the grout and tiles may become damaged when they contact the heated water.

Place your nylon brush or scrubbing pad into a nylon cleaning bucket. This will help transport dirt out of your shower and onto the surface of your cleaning device, where it can be easily removed with a blast of steam or pressure from the sprayer.

Start Steam Cleaning Grout

Turn on your steam cleaner (if you are using one) or turn on your pressure washer to its highest setting (if you are using one). The steam cleaner should be equipped with an extra-long hose that reaches all the way up into the shower tile grout for maximum reach and cleaning power.

Point your steam cleaner towards the grout between each set of tiles on the ceiling and walls of the shower. This will be done to loosen any dirt or soap scum that may have become stuck between the grout lines. Starting in one corner, begin scrubbing away at the grout between each set of tiles. This should be done with a firm scrubbing motion to get down into every nook and cranny where dirt may have accumulated.

Sealing Grout After Steaming

Use the mixed solution of vinegar and water to scrub away any soap scum or dirt that does not come loose using your steam cleaner. Although you may have already removed most of the dirt and grime using your steam cleaner, some residue will remain after the steaming process. This is why it is recommended to scrub away the remaining dirt with a diluted solution of vinegar and water.

After you have applied the vinegar solution, allow it to sit on your shower grout for 15 minutes. By letting this mixture sit on your shower tile grout, you will be allowing its acid content (which is found in vinegar) to work its way into any stains or grease buildup that may remain within the grout lines of your shower. After the 15-minute wait time, use a stiff nylon brush or scrubbing pad to scrub away any remaining soap scum or dirt. This will bring your shower grout to its original appearance and ensure that it stays that way for the foreseeable future.

Use your steam cleaner again to steam clean your shower tile grout one more time. The reason for this is that you will likely have left a few spots of grime behind after cleaning it with the vinegar solution. This is why it is recommended to go over your entire shower one more time using the steam cleaner to ensure that all stubborn dirt and soap scum are removed completely from the once dirty grout.

How to Choose the Best Steam Cleaner for Grout

You want to know how to steam clean shower tile grout. The grout is the material that seals the tiles together, and if it’s dirty, the surface is not going to be nice. There are things you need to consider before buying a steam cleaner for this purpose.

Handheld steamers are helpful for grout cleaning but not as powerful as full-size steam cleaners. If you want to use this type of cleaner, make sure it has plenty of power and performs well on new grout.

Size and Weight

It should be lightweight enough for you to carry it wherever you go. You can also choose one that delivers continuous steam blasts at about 80 to 100 PSI (pounds per square inch) at the lowest setting. Most other steam cleaners produce a high volume of hot water, which dilutes your cleaning solution and makes it difficult for you to apply it properly and effectively.

Attachments and Reach

Make sure that it has the right attachments. For example, you might want a scrubbing brush attachment and a separate hand tool with a squeegee. Some cleaners are equipped with built-in brushes and hand tools or extension wands that you can use for draining the hot water from various spots.

If you need to clean a vertical surface, you will have to buy a cleaner that offers a good reach. The best cleaners should have at least 12 to 15 feet of reach or even higher.

Tank Capacity

The tank is where the cleaning solution will be stored. If you plan to use a detergent for cleaning, you should buy a cleaner that has a large tank or that comes with a large container of rinse solution to allow you to clean your grout and rinse it well. This will help ensure good coverage each time you clean even large areas, like the surface of your shower floor.


It’s always important to buy products from manufacturers who are confident in the quality of their machines. This is why they provide warranties or guarantees when you purchase their products. Also, check out the length of the warranty so that if you do experience any problems with your machine during or after your 30-day guarantee period, you can get it fixed or replaced without any hassle.


When you’re considering buying a handheld steam cleaner, it’s important to know how these tools work. While handheld cleaners work well for some jobs, full-size models are more powerful and versatile. In the end, you should have the best steam cleaner for grout in store that can perform well on all kinds of tile surfaces. In fact, just as with any other cleaning task, if you want to have a good job done on your tiles, get the right equipment for the job.
