In the course of managing and maintaining hundreds of rental properties, we discovered the mold removal solution that works the best for us.

But in order to make this a true review, we wanted to test other popular products. So, we tried 15 different products over the last three months and talked to 7 restoration professionals to find the most effective mold and mildew cleaner.

What we discovered is that some of the highly rated and expensive products don’t perform better than simple bleach.

We also found that killing mold on different surfaces requires different products. For example, bleach doesn’t work very well on porous surfaces and can ruin some materials.

The best mold cleaner had to work on every surface and be environmentally safe. That mold removal product is Concrobium Mold Control.

Our Pick for the Best Mold Remover

Concrobium Mold Control

Concrobium Mold Control is mold remediation and mold prevention in one.

It’s a non-toxic antimicrobial solution used by restoration professionals.

Why is the Concrobium Mold Control our favorite?

Concrobium is our pick because it works really well, it’s odorless and safe on most surfaces. Personally, we have used it successfully on drywall and wood. It also works on tile, wood, concrete, plastic, drywall fabric and metal.

How does it work?

Concrobium works as it dries out by crashing the mold and mildew roots. Here is a short video showing it in action.

What is the best way to apply it?

The best way to use this mold remover is to dry out the area first, soak it and let it dry. It’s a good idea to use a dehumidifier as the humidity needs to stay below 60%.

Concrobium can be applied by fogging, spraying or brushing over the area that needs to be remediated. 

Fogging is the best way to apply because it reaches all areas and clears the air from mold spores. Good fogging machines tend to be expensive but they can also be rented from Home Depot if the job is smaller. If you own many units, it may be worth the investment because the fogger can be used for other applications like odor control.

The Best Bathroom Mold Remover

Clorox Bleach Gel

The Clorox Clinging Bleach Gel is perfect on grout, caulk, and around the shower doors.

How does the Clinging Bleach Gel work?

Apply the bleach gel on moldy caulk, grout and other area that need treatment and leave for 30 mins to one hour. 

The magic of this product is in the clinging gel. If you spray any liquid solution on the shower walls, it just disappears down the drain. The clinging gel stays on in good concentration even on vertical surfaces and that’s what makes it so effective.

We often use it on moldy caulk around the shower and shower doors. 

Be careful not to mix this with other products as it can get toxic. After you use it, rinse everything well.

Honorable Mentions

RMR-86 Instant Mold and Mildew Stain Remover Spray

This product is the highest-rated mold removal on Amazon

and when we tested it we were not disappointed.

It cleaned our shower perfectly.

However, this is a bleach-based solution

so the smell is very strong and this is

definitely not suitable for any porous surfaces.

Tilex Mold & Mildew Remover

This is a Clorox Tilex product and after testing,

it worked as well as any of the other bleach-based products.

The main active ingredient is sodium hypochlorite,

most commonly known as bleach.

The surfaces that can be cleaned with any bleach-based

mold removers are glazed ceramic tile, grout, tubs, fiberglass,

shower doors, vinyl shower curtains, sinks, and no-wax floors.
