Outdoor tile can add beauty and style to patios, pool decks, walkways and more. However, outdoor tile requires regular cleaning to keep it looking its best. With the right techniques and products, cleaning outdoor tile is straightforward. We will walk through all the steps to keep your outdoor tile clean and vibrant.

Supplies Needed to Clean Outdoor Tile

Cleaning outdoor tile does not require many supplies. You likely already have most, if not all, of what you need at home. The basic supplies include:

Bucket
Scrub brush
Clean, soft cloths or sponges
Broom
Garden hose
Tile cleaner
Grout cleaner

Optional supplies that can help with tough stains or dirty grout include:

old toothbrush
Spray bottle
White vinegar
Baking soda
Grout sealing product

Gather your cleaning supplies and inspect the tile. Make notes on any problem areas or stains. This will help focus your cleaning efforts on the most crucial areas.

Prepare the Tile Surface

Before cleaning, it helps to prepare the tile surface. Follow these tips:

Sweep debris – Use a broom to remove any leaves, dirt or other debris from the tile. Getting rid of surface debris makes cleaning easier.
Hose away dust – Blast tile and grout with water from the garden hose. Let the water run over the entire area for 2-3 minutes. This washes away loose particles.
Inspect stains – Look closely at the tile and grout. Make notes on any stains or trouble spots. You may need to use stain-fighting cleaners on these areas.
Work in sections – Divide the outdoor tile into workable sections. Clean one section at a time for best results.

Now the tile is ready for cleaning.

How to Clean Outdoor Tile

The actual cleaning involves scrubbing both tile and grout. Follow these steps:

Clean the Tile Surface

Fill bucket with warm water – Warm, soapy water works best for cleaning tile. Fill a bucket about halfway with warm water.
Add tile cleaner – Squirt a healthy amount of tile cleaner into the bucket. Check the bottle for exact dilution. Stir the water gently to mix.
Dip brush and scrub – Dip a scrub brush into the cleaning solution. Scrub the tile surface in circular motions. Apply light pressure as you scrub.
Rinse – Use a garden hose to rinse away the cleaning solution. Check for any remaining dirty areas and re-clean if needed.
Soak up water – Use old towels or rags to soak up standing water on the tile. This will help surfaces dry faster.
Work in sections – Divide the outdoor space into workable sections. Clean, rinse and dry one section completely before moving on.
Check for stains – Inspect the tile when wet. Make notes on any remaining stains. Use a targeted stain remover on these areas.
Allow to dry – Let tile air dry completely before using the space. The area should be walkable within an hour.

Clean Grouting

Grout needs special attention to remove built-up dirt and stains:

Use grout brush – Dip a grout brush in the cleaning solution. This thin brush fits easily into grout lines.
Scrub gently – Move the grout brush in a gentle back-and-forth motion across grout lines. Avoid excessive pressure.
Rinse thoroughly – Rinse the grout several times with clean water. Check closely that all dirt and debris are gone.
Spot treat stains – For stubborn grout stains, spot treat with a paste of baking soda and water. Let sit 5-10 minutes before scrubbing.
Whitening options – For dingy grout, use a whitening cleanser formulated for grout. Always test first in an inconspicuous spot.
Seal yearly – Apply a penetrating grout sealer once a year. This protects grout and makes regular cleaning easier.

Follow these steps each time you deep clean outdoor tile. For heavy dirt, repeating the process may be necessary.

Tips for Cleaning Tough Outdoor Tile Stains

Outdoor tile sees all types of stains from food, drinks, leaves, mud and more. Try these tips for removing stubborn stains:

Oil stains – Sprinkle baking soda on the stain. Scrub using a stiff brush and rinse. Repeat as needed.
Rust stains – Use a rust remover designed for tile. Or make a paste with lemon juice and baking soda. Let sit for 5 minutes before scrubbing.
Leaf stains – Mix equal parts warm water and bleach in a spray bottle. Lightly spray on stains and let sit 5-10 minutes. Scrub and rinse.
Mud – Let mud stain dry completely. Use a plastic scraper to remove excess. Mix water and dish soap in spray bottle. Spray on stain and scrub with a brush.
Wine – Blot wine immediately to absorb excess liquid. Mix baking soda and water into a paste. Spread on stain and let sit 20-30 minutes. Scrub and rinse thoroughly.
Grease/food – Spray stain with degreasing cleaner like Formula 409. Let sit 5 minutes. Scrub with a stiff nylon brush. Rinse thoroughly. Repeat as needed.
Mold/mildew – Treat mold promptly to avoid permanent damage. Use a mold and mildew remover made for tile. Spray on mold and let sit. Scrub and rinse thoroughly.

For best results, treat stains immediately. Avoid using harsh chemicals that could damage the tile or grout. Test stain removers in an inconspicuous area first.

How Often to Clean Outdoor Tile

The cleaning frequency depends on the amount of use and traffic:

High-traffic areas – Clean monthly during warm months when tile gets more use. This includes patios, pool decks and frequently used walkways.
Moderate traffic – Clean every 2-3 months for occasionally used tile like garden paths or back yard tile.
Low traffic – Clean 1-2 times a year for tile in rarely used areas. Still clean during fall to prep for colder months.
As needed – Clean whenever tile appears visibly dirty. Don’t let debris sit for prolonged periods.
Before sealing – Deep clean tile before applying a fresh sealant. This helps the sealant adhere and penetrate.
After pressure washing – Always give tile a thorough cleaning after using a power washer. Remove any loosened dirt.

Develop a regular cleaning schedule based on usage. More frequent light cleaning helps avoid deep stains that require heavy-duty cleaners.

Cleaning vs. Disinfecting Outdoor Tile

Cleaning removes dirt, debris, stains and grime from tile surfaces. Disinfecting kills germs and bacteria using chemical disinfectants. Both are important for healthy outdoor tile:

Clean regularly – Regular mopping and scrubbing keeps tile free of unsightly stains. This is generally done weekly or monthly.
Disinfect occasionally – Disinfect high-touch surfaces like pool decks occasionally to kill germs. This is especially important after events or gatherings.
Cleaners vs. disinfectants – Use cleaners like soap, vinegar and baking soda for routine cleaning. Use EPA-registered disinfectants when disinfecting is needed.
Scrubbing is key – Disinfectants require scrubbing to physically remove and kill germs. Spraying alone is not sufficient.
Rinse thoroughly – Always rinse completely with clean water after using disinfectants. Residue left behind can be harmful.

Regular cleaning removes dirt and stains. Periodic disinfection kills germs for a healthier outdoor space.

Supplies to Make Homemade Outdoor Tile Cleaners

Harsh cleaners can damage tile and grout. Homemade cleaners using gentle ingredients are an effective, affordable alternative. Try these options:

All-Purpose Homemade Tile Cleaner

1/2 cup white vinegar or apple cider vinegar
1 gallon warm water
20-30 drops essential oil (optional for scent)

Mix ingredients in a bucket. Use immediately or store safely for later.

Baking Soda Scrub

1/2 cup baking soda
Water to form a paste
Optional – 5-10 drops essential oil

Mix baking soda and water to a spreadable consistency. The baking soda provides gentle scrubbing power.

Vinegar-Dish Soap Solution

2 cups warm water
1/4 cup white vinegar
1 tsp liquid dish soap

This all-purpose solution cuts through dirt and grease. Store safely in a sealed container when not in use.

Hydrogen Peroxide Disinfectant

3% hydrogen peroxide
1/2 tbsp liquid dish soap
1 cup warm water

Mix ingredients in a spray bottle. Spray on tile and let sit 5-10 minutes before scrubbing.

Make homemade cleaners as needed. Clearly label contents and store out of reach of children.

Power Washing Outdoor Tile

Power washing can deep clean outdoor tile and remove built-up grime. Follow these tips:

Use lowest setting – High pressure can damage grout or tile glaze. Use the gentlest setting that effectively cleans.
Hold nozzle at angle – Aim wand at a 45 degree angle 6-12 inches from surface. This avoids digging into grout lines.
Limit grout washing – Take care when power washing grout joints. The force can erode grout over time.
Check for damage – Inspect tile and grout closely after power washing. Repair any chips, cracks or missing grout right away.
Clean stained areas – Use targeted stain cleaners on any remaining stained or discolored areas. The stain may reappear if not removed entirely.
Rinse well – Remove all soap residue by thoroughly rinsing the entire surface with clean water.
Allow to fully dry – Let tile dry completely before sealing, staining or using the space. Drying may take 24 hours or longer.

Power washing can save time when deep cleaning outdoor tile. Be cautious to prevent tile damage or leaving stains behind.

Tips for Cleaning Stone vs. Ceramic Outdoor Tile

Stone and ceramic tiles require slightly different cleaning methods:

Natural Stone Tile

Check manufacturer guidelines – Use cleaners designed for natural stone. Avoid acidic cleaners.
Soak up spills – Immediately blot wine, coffee and other staining liquids. Don’t wipe, which can spread the stain.
Use mild cleaners – Stick to gentle cleaners like dish soap, hydrogen peroxide or baking soda. Avoid abrasive scrubbing.
Seal regularly – Seal natural stone tile every 1-2 years to protect from stains.

Ceramic/Porcelain Tile

Scrub stains – Use a stiff nylon brush and baking soda paste to scrub stains. The durable glaze can handle aggressive scrubbing.
Use acidic cleaners – Vinegar, lemon juice and commercial cleaners work well to dissolve mineral deposits and stains.
Check roughness – Drag a coin across the surface. If it scratches, avoid acidic cleaners which get trapped and cause damage.
Power wash cautiously – Use a wide nozzle and keep the pressure wand constantly moving to avoid damage.

Know your tile type and always test cleaners in an inconspicuous spot before using on the entire area. This prevents accidental damage.

Signs It’s Time to Professionally Clean and Seal Outdoor Tile

While DIY cleaning works for routine maintenance, periodically bringing in a professional for deep cleaning and sealing rejuvenates tile. Consider professional services if:

Tile is heavily stained or dingy despite regular DIY cleaning.
Grimy grout needs heavy-duty cleaning methods.
Outdoor tile has never been professionally cleaned.
