Best Shower Mold Remover

Mold is known to thrive in showers as it is an area that is regularly exposed to water, heat, and moisture. From the showerhead to the grout and drains, mold that is left untreated will soon become invasive. If left to grow, mold can become an eyesore, transforming what was once your pleasingly designed shower and bathroom into an area that is overcome with specks of black and white furry-looking growth. It also presents risks to your health and can be particularly dangerous for those who suffer from asthma or allergies. A shower mold remover provides an effective solution to this issue. Applying the product to the infested surface will break down and remove the mold and when used as part of a regular cleaning routine will help to prevent the regrowth of the mold in the future.

Best Shower Mold Remover Buying Guide

There are several factors that we would advise you to consider before selecting a shower mold removing product.

The market is inundated with a variety of different cleaning products some of which will be more effective in targeting mold than others.

Applying the following criteria to your search will help you to select the best product for your cleaning needs and the amount of mold that you are dealing with.


The effectiveness of the product is likely to be one of the most influential factors upon your purchase. You will find that many products claim to be 99.9% effective in killing bacteria and getting rid of mold and mildew.

Many will have been EPA-registered which shows that it has undergone testing and is not likely to cause any adverse effects. Most products of this kind have fast-acting formulations which will work at speed to get rid of the stains caused by the mold, whilst others will take longer to work.

If you are uncertain about a product’s effectiveness and would like further assistance before making your purchase, it is worth checking out reviews from customers who have experience of using the product. This will enlighten you as to whether the product is effective in achieving the desired results and therefore worthy of your purchase.

The Formulation

Most mold and mildew removal products are formulated with bleach. However, there are a few available that are not. The bleach will penetrate the surface to remove any stubborn particles leaving the surface appearing visibly improved.

It is worth noting that a lot of bleach products contain heavy fumes, hence why they ooze a strong smell. Should bleach come into contact with your skin, it can result in possible irritations or reactions.

For these reasons, it is important to be cautious when using bleach formulated products. You may want to wear gloves to prevent the product from coming into contact with your skin.

As mentioned, there are products available that do not contain bleach but this doesn’t mean that they aren’t as effective. They simply just do not contain the fumes and are a safer option which will likely be preferred by those who are hesitant about using bleach products.

Using the Product

Typically, shower mold remover products came in bottles designed with a spray trigger handle. This makes it easier to apply the formula directly onto the problematic surface and is also a feature that is likely to be appreciated when tackling larger jobs.

Additionally, it makes it easier to apply the product to hard-to-reach areas too. A great thing about many of these products is that they do not require a lot of effort on your behalf. Unlike many other cleaning products, you aren’t required to scrub the product into the surface to encourage it to work and achieve better results.

Instead, you simply need to spray the product onto the surface and allow it a couple of seconds or minutes, as per the guidelines, to work, and then it can either be wiped off with a damp cloth or rinsed off.

Size of the Bottle

The majority of these products came in at least a 30 Fl Oz bottle. A product of this size is more than likely to see you through many uses so that you aren’t regularly having to purchase new bottles.

This is going to be particularly important if you are working with a large mold or mildew-infested area because you aren’t going to run out of the product partway through the cleaning process.

Some brands will also offer their products in multiple sizes with some options larger than this. This allows you to choose the correct sized bottle according to the demands of the cleaning task and the amount of product that you are likely to require to combat the issue.

The Smell

Some mold-removing products, particularly those that contain bleach, have a strong smell. Because of this, it is important to ensure that the bathroom, or room that it is being used in, is properly ventilated. This will allow the scent to dissipate with the air rather than linger.

Also, try not to spend more time in the bathroom than is necessary. If the product takes a couple of minutes to work you may wish to step outside of the bathroom as it does so.

If the product takes a couple of seconds to work, you can wipe or rinse it off and then exit the bathroom as this will prevent the smell from becoming overwhelming.


A great thing about many of these products is that they are super versatile. Not only can they be used to clean your shower but they can also be used to clean bathtubs, tiles, countertops, sinks, hardwood floors, hard plastics, grout, and much more.

Of course, it is important to check the specifications of the product before using it on different surfaces to ensure that it is suitable. Those that are multipurpose products will not limit you to the variety of surfaces that you can clean.

The Quality

If a product is poorly packaged there is a greater chance that it will leak during shipping. Of course, this will mean that you are confronted with a mess when receiving the product.

Poor quality packaging can also make the product difficult to apply onto the surface too so it is worth selecting a product that isn’t likely to provide you with this issue.

The Price

Most mold-removing products retail below the $20 price range, although you will find some that exceed this amount, particularly those that are sold in multipacks.

Consider whether those that come in multipack quantities are going to be better value for you depending on the severity of the job that you are tackling.

If you are working with a smaller budget, you will be pleased to know that there are many great value products available that accommodate this.

It’s worth noting that those which appear surprisingly cheap may not achieve the same standard of results as those that are slightly more expensive.
