Categories of Use

The five categories outlined in ANSI A326.3 enable manufacturers to specify product use classifications for their products according to the products’ slip resistance characteristics. The standard also includes possible areas of use:

​​1. Interior, Dry (ID): indoor shopping malls (with the exception of food courts), hotel lobbies, office buildings, showrooms, and home interiors without water sources.

2. Interior, Wet (IW): entry foyers, public restrooms (without showers), grocery stores, “front of the house” in fine and casual dining restaurants with a closed kitchen, and home interiors including bathrooms and kitchens.

3. Interior, Wet Plus (IW+): public showers, interior pool decks, locker rooms, covered exterior areas, steam rooms, “front of the house” applications in restaurants with an open kitchen, and in “front of the house” applications in quick service, fast-casual, and self-service restaurants, and food areas in gas stations.

4. Exterior, Wet (EW): level outdoor living spaces including pool decks, walkways, patios, and sidewalks.

5. Oils/Greases (O/G): level areas regularly exposed to automotive fluids, “back of the house” fast food or family-style restaurants, food preparation areas with grills or deep-fry equipment, and any area where oil, grease, and/or fats may be present.

Reference categories ID and IW are based on DCOF criteria, while reference categories IW+, EW, and O/G, are required to be “manufacturer-declared.” (As an option, the IW category can be manufacturer-declared.) Manufacturers can specify one or multiple categories for a given product.

Porcelain tile is designed to provide a lifetime of worry-free beauty and functionality, and with a minimum amount of routine care and cleaning, it will maintain its appearance for years to come.

All Wonder Porcelain tile products are certified by the Porcelain Tile Certification Agency, which means they will provide the exceptional performance, durability and ease of maintenance that makes porcelain tile the superior choice for floors, walls, and countertops.

Follow the cleaning and maintenance guidelines below to keep your tile looking like new now and well into the future.


The most important step of your tile care and maintenance routine is the first one. By removing installation debris and grout residue immediately following installation, you will prevent the formation of a dull ‘haze’ or other buildup on the tile’s surface that could become increasingly difficult to clean as time passes.

Grout residue can be removed following setting the tile per the materials manufacturer’s instructions. If residue remains after this initial cleaning, further consultation with the manufacturer may be required.

Once the grout residue is successfully removed, porcelain tile can be scrubbed clean with a neutral detergent and hot water solution then rinsed with clean water and immediately towel dried. This process may need to be repeated several times to properly clean the tile.

Excess water can be removed with a wet vacuum or squeegee. Neutral cleaning detergents are readily available at any retail outlet that sells tile cleaning products and are identified on the label.


Porcelain tile is the easiest to care for among all floor covering materials. It does not allow accumulation of dust mites, mold, germs or bacteria and is hypoallergenic and safe for people with allergies and asthma.

Day-to-day care of porcelain tile requires minimal time and there is rarely a need for chemical cleaners to be used on a regular basis. Sanitary conditions and a clean appearance can be accomplished through the following steps:

  • Sweep or vacuum the surface of tile floors; for walls and counters, wipe down with a soft dry cloth to remove dust, soil, and or other debris.
  • Damp mop floors with clean, warm water, rinsing the mop and changing water frequently for large areas.
  • Daily grout cleaning is generally not required, but if necessary follow manufacturer’s guideline.
  • Always wipe spills immediately using a mild neutral cleaner if necessary.
  • For walls and countertops, use a soft cloth with warm water to gently wipe tile surfaces.

Polished tile, while remaining a low-maintenance flooring option, may require a slight variation in the regular maintenance routine, as well as the use of penetrating sealers during the installation process. Your professional contractor will be able to apply these sealers, which generally do not require additional applications after installation.

To clean polished tile:

  • Sweep or vacuum loose dirt and debris.
  • Use a dry mop over the area to further remove any dust or light soil from the surface.
  • Reduce the amount of cleaner used on unpolished tile starting with 50% less solution and reducing further if needed going forward.
  • Rinse with warm water, using just enough to effectively remove the cleaner and debris but not enough to accumulate or pool on the surface of the tile.
  • Dry completely with a soft, clean cloth to prevent water spots and ensure shine.


Occasionally you may find your tile requires a deeper cleaning especially in high traffic areas, entrances and exits. Follow these steps as needed:

  • Sweep or vacuum loose dirt and debris.
  • If needed, use a nylon bristle brush or scrubbing sponge to scour surface. Apply gentle pressure, just enough to remove set in dirt, soap scum or other deposits, testing first in a small area.
  • Use the recommended ratios of cleaner to water on the product label—too much cleaner may be difficult to rinse and too little may not effectively clean your tile.
  • Apply a sufficient amount of the cleaning solution to the tile surface without over saturating and allow it to remain for as long as recommended on the label, typically no more than 10 minutes.
  • For large floors, work in areas small enough to allow rinsing before product begins to dry, which can result in a film or coating that will be difficult to remove.
  • Use clean, warm water to rinse surface, repeating as necessary to remove all loosened dirt, debris, and residual cleaner.
  • Use a dry mop or towels to remove clean rinse water from the tile surface.


Rarely your tile may require heavy duty cleaning to remove problem stains or following challenging situations such as leaks, flooding or major spills and contamination. If you are unable to clean your tile after repeat application of general household cleaners and more thorough scrubbing, equipment such as floor scrubbers or buffers may be necessary. It is critical to follow usage instructions exactly to avoid damaging your floor, or you may wish to hire a flooring or maintenance professional. Not only do these professionals have expertise required to safely and effectively operate such machinery, but they may also have access to professional-grade cleaners that are not available to the general public.
