Steam extraction cleaning is considered to be the most effective method of cleaning unsealed grout.
Make a paste out of baking soda and water. Avoid using vinegar as this could neutralise the baking soda before cleaning. Use a stiff-bristled brush (like an old toothbrush) to apply the paste to the grout lines and scrub them clean.
Remember, you can only use vinegar on sealed grout. If you have unsealed grout or it needs resealing, use only the baking soda solution. You'll also need to be a bit more careful with the scrub brush.
Grout helps hold tiles in place, preventing them from shifting and becoming loose. Unsealed grout is susceptible to moisture penetration, which can lead to the deterioration of the grout itself. Over time, this degradation can result in weakened grout lines and tiles that may become loose or crack.
DO NOT USE VINEGAR. Vinegar is acidic and will seep into the pores of the grout and destory it slowly over time.
If you're a die-hard DIYer, using Dawn dish soap alone can be a safer option for mild cleaning. Dilute a small amount of Dawn in warm water, scrub the grout with a soft brush, and rinse thoroughly.
Magic erasers are a fantastic way to get grout very clean, very quickly. The downside is, the grout will rip through your magic erasers in a hurry. You'll go through more of them than you're used to, and that means this is one of your more expensive options.
The best answer, in a word, is money. It costs more time and material to seal grout and there is little or no perceived benefit (until, of course, the grout gets stained or starts to crack). A superior product would cost more to purchase and install, again for no perceived benefit over the less costly unsealed grout.
If you notice your tile grout is changing color, specifically getting darker when it's wet, you can be pretty sure the seal is broken and needs to have some grout sealing reapplied by a professional. You may also notice dirt and grime gathering between your tiles that doesn't wipe off when you apply a grout cleaner.
Grout tends to wear away more quickly when it is not sealed, so it will crack, discolor and become hard to manage when cleaning. This will force you to replace it more often than if it was sealed, leading to higher costs overall.
Sealed grout can stand up to the high temps and moisture, whereas unsealed grout isn't as durable. “Steam cleaning can damage grout, but mainly if the grout is unsealed or if you are using high-pressure steam,” explains Sarah McAllister, a cleaning expert and the founder and CEO of GoCleanCo and House Work.
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 compound. Mixing the two together creates a reaction that can penetrate the grout lines and free dirt and debris.
Impact on Grout: Even a single application of vinegar can begin to break down the sealant on your grout. As the sealant degrades, dirt and moisture penetrate, leading to discoloration and staining.
Yes, hydrogen peroxide is a natural neutral cleaner that is safe to use on grout. Hydrogen peroxide and baking soda produce oxygenated bleach, which is highly effective for cleaning grout.
The price depends on the tile material and size, the condition of the grout, and whether you hire a professional or DIY. The average cost to seal grout is $150 to $250 for 160 square feet of space, including materials and labor, though the price depends on the size of your tiles and the condition of your grout.
Check the color and condition in some of the higher-traffic areas of the room. If you notice any chipping or cracking in the grout, it won't respond well to cleaning and will most likely just break apart if you try to clean it with any kind of physical force.
Porous grouts attract water, dirt, oils, etc. While the tile industry does not require sealing, it is always recommended, especially in wet or high-traffic areas. Penetrating sealers are the most commonly used and offer high water, chemical and stain resistance.
You can seal the grout the day after you applied it or 100 years later. If it isn't dirty, seal all three sides of the shower with a tile sealer or masonry sealer. That will make the grout water-resistant, if not waterproof, and help prevent the growth of mold and dirt.
Any type of material can be susceptible to cracking if not sealed correctly. This will keep moisture out to keep the grout from deteriorating.
High-traffic floor grout: Should be sealed every six months to one year. Guest bath and shower grout: Should be sealed every year or two, depending on frequency of use. Backsplash grout: Backsplashes in high-traffic areas should be sealed once yearly on average.
Steam extraction cleaning is considered to be the most effective method of cleaning unsealed grout. The steam and detergent mixture loosens the dirt and grime before it is extracted from the pores using a vacuum. However, you might need to hire or buy a floor steamer to use this method.

Or any other delicate surface, for that matter, like silverware, glass, or metal surfaces. Dry erasers have the abrasiveness of a 3000 grit sandpaper – very fine, but can still mar shiny surfaces – like your stainless steel appliances!
