Yes, Dawn dish soap is excellent for cleaning grout because its gentle, grease-cutting formula will not strip sealers or discolor tile.

Baking Soda and Peroxide Mixture
Some professionals swear by a simple mixture of baking soda and peroxide to clean grout. Hydrogen peroxide is an acid, and baking soda is a base. Mixing the two creates a reaction that can penetrate the grout lines and free dirt and debris.
Just a few more important points: As the grout can absorb the soap as well as a stain, do not clean with oil or wax based cleaners (Murphy's Oil soap, Pine Sol, etc.). These products will leave a waxy or oily film in the grout. Even good alkaline cleaners, if not properly rinsed, will leave a sticky soap film.
Yes, vinegar is generally bad for tile grout if used frequently or for routine cleaning. Because it is acidic, vinegar can etch, dissolve, and weaken the cement and calcium carbonate components in grout over time.
Hotels keep glass shower doors spotless by combining strong commercial cleaning agents with routine maintenance and smart preventative coatings. Because they deal with heavy daily guest turnover, housekeeping staff rely on quick but highly effective strategies to prevent soap scum and hard water buildup.

Yes, you can use a Magic Eraser on grout. It acts like micro-sandpaper, making it highly effective at lifting stubborn dirt, grime, and mildew. However, because it is abrasive, you should scrub gently to avoid etching the grout or scratching surrounding tile.
Professionals use heavy-duty, commercial-grade acidic and alkaline cleaners, often paired with high-pressure rotary hot-water extraction machines. For stubborn stains, they frequently rely on professional-strength stain removers, or a simple DIY mix of baking soda and hydrogen peroxide.
Yes, OxiClean is safe and highly effective for most types of tile grout. Its active ingredient, sodium percarbonate, relies on oxygen to lift dirt and stains without the harsh, damaging effects associated with chlorine bleach.
Cleaning grout and joints with a steam cleaner
The hot steam itself loosens stubborn dirt and deposits, and the high level of heat effectively prevents mold formation. In most cases, you therefore do not have to use detergents at all, thus protecting the environment and your own airways.
The best way to clean tile and grout is with a DIY paste of baking soda and hydrogen peroxide. This natural mixture foams to lift dirt and whiten grout. For tougher, set-in stains or mold, use a commercial product like Zep Grout Cleaner and Brightener or Tilex Mold and Mildew Remover.
Professional tile and grout cleaning costs $0.50 to $3 per square foot, depending on your area size. The size of your tiles and grout condition shape how long your job takes and the cleaning method. Account for add-ons like grout sealing, repairs, or mold treatment that add $150 to $500 to your total.

Clorox™ Disinfecting Bleach is safe for use on sealed grout and other hard, nonporous surfaces when used as directed. However, it should not be used on unsealed, damaged or porous grout, as it may cause discoloration or surface degradation.
