Bleach is the most effective method for removing mold from shower grout. Method One: Make a solution of one-part bleach and four-parts water, and put it in a spray bottle. Spray the affected area and scrub with a brush after 30 minutes. Rinse with water and repeat if necessary.
Use a Bleach Solution
Chlorine bleach is known to kill mold spores but also disinfect and remove soap residue buildup. Prepare a one-part bleach and four-part water solution in a spray bottle. Spray the solution on the moldy grout and let it sit for about 30 minutes.
Discolorations in your tile and grout aren't just unsightly—sometimes they are downright dangerous. The dark spots on grout are most likely the result of mold, mildew or plain old dirt buildup. It is important to determine what you're dealing with first, so you can wipe it out with the appropriate treatment plan.
While it is possible to use bleach to kill mold as well, experts agree that vinegar is a much better option.
Spray vinegar onto the moldy surface and leave it for an hour. Then wipe the area clean with water and allow the surface to dry. Any smell should clear within a few hours. While it's safe to use on most surfaces, vinegar is unlikely to be effective at cleaning mold off of soft surfaces.
Why vinegar and baking soda: Vinegar is a super powerful tool! It kills around 82% of mold species because it has acetic acid. On the other hand, baking soda is great because it absorbs moisture.
What's the best homemade grout and tile cleaner? Mix together 1/2 cup of baking soda, 1/4 cup of hydrogen peroxide, and 1 tsp dish soap. Apply cleaning mixture onto the grout, wait 5-10 minutes, scrub, sweep up the excess baking soda, and rinse.
Grout that hasn't been sealed, needs to be resealed, or is in poor shape should not be cleaned with vinegar. The vinegar penetrates into the pores of the grout, further weakening the material. Over time, vinegar will deteriorate the condition of the grout by etching or wearing it away.
Hydrogen peroxide is one of the best options for removing mold from unsealed and colored grout. Unlike bleach, peroxide can work on porous materials, exactly where mold wants to grow.
Vinegar. White distilled vinegar is an affordable, natural solution to removing black mold. Its antibacterial acidic characteristics are exactly what you need to get the job done. Pour the undiluted vinegar into a spray bottle to apply to the area, or just go for it and pour that vinegar right onto the mold stains.
We highly advise against using ammonia or bleach to clean any grout. Cleaning solutions that contain bleach or ammonia will not only work to erode your grout over time, they will cause your grout to become even dirtier by leaving a film behind, which attracts dirt.
The best solution for cleaning mold in a shower is an equal mix of water and white vinegar, says Michael Golubev, CEO and expert at Mold Busters. Mixing the two in a spray bottle is the easiest way to kill mold spores.
The Australian Environmental Mycology Laboratory recommends that surface mould be vacuumed up with a HEPA vacuum, then to wash the area with an 80/20 solution of water and vinegar. White vinegar treatment is known to be the most effective means of removing mould.
Showers and bathtubs are notorious for housing mold and mildew because of their humid, damp, and usually dark environment. To effectively kill mold in bathrooms, we recommend Clorox Plus Tilex Mold & Mildew Remover. The bottle's Smart Tube technology also allows it to spray every drop and avoid waste.
The easiest way to clean grout without scrubbing involves hydrogen peroxide and baking soda. Mix the two into a paste with some dish soap and apply to the grout lines. Alternatively, you can use a cleaning solution of water, vinegar, lemon juice, and baking soda.
Pour enough undiluted white vinegar into the empty spray bottle to cover the area of mold growth. Spray the mold directly, fully saturating it with the vinegar, and allow the vinegar to sit for at least an hour. Don't be tempted to scrub or rinse; the mold needs time to completely absorb the vinegar.
Black mold is toxic, so it is usually safer to ask professionals to remove it, especially if people in the household have respiratory conditions like asthma or allergies.
Cleaning vinegar, which contains 6% acetic acid, is the best type for killing mold. White vinegar containing 5% acidity will also work just fine. If you don't already have some at home, white vinegar can be inexpensively purchased at most grocery stores.
