Hey guys, today I am here to talk about the proper ways to clean fiberglass swimming pool steps.

Fiberglass pool steps are made from the superior quality resins.

They have several advantages over other ladders.

People prefer them because they are more durable, less expensive, and more stable.

Fiberglass pool steps generally get dirty due to people walking over them and also because of extreme weather conditions, and also sometimes from pool water.

The best way to maintain fiberglass pool steps is to clean them on a regular basis.

This helps in preventing dirt accumulation.

It also eventually helps to keep the pool water clean from dirt.

But cleaning fiberglass pool steps require some efforts from your side.

However, with proper equipment and technique, this cleaning process can be done smoothly.

Let us see what equipment can be used to clean these fiberglass pool steps.

1. A pool rake

2. Mild Vinyl Tile Cleaner

3. Piece of cloth that is abrasion resistant

4. A pool brush with gentle bristles.

Now by following the simple steps below, you can easily keep your fiberglass steps clean and hygienic.

Step 1: Using the pool rake, you need to first push the scum towards the pool main drain.

In case of algae, it does not get stuck in the fiberglass pool pores.

So, removing algae is a straightforward process.

Step 2: For cleaning the discolored dirty parts gently rub them with mild vinyl tile cleaner.

The use of strong abrasive cleaners is not advisable on fiberglass pool surfaces.

Step 3: After the above step, gently wipe the cleaner and muck using a non-abrasive cloth piece or towel.

If you find the stains hard, then use a gentle pool brush to scrub the stains smoothly.

Step 4: Finally, make sure that the pool steps should be neatly wiped off without leaving any residue.

The cleaning equipment plays an important role in the fiberglass pool steps maintenance.

Especially the brushes and non-abrasion cloths.

So, you need to choose them carefully.

In the next part, I will go much deeper and will provide more information regarding cleaning all types of fiberglass pool stairs and steps.

Stay tuned and don’t miss any of these details.

How Do You Clean Fiberglass Pool Stairs?

The factors like frequent usage, weather conditions, and pool water may cause the fiberglass pool stairs to get dirty.

The best way to ensure cleanliness of these stairs is to maintain a regular cleaning regime of those stairs.

Otherwise, once the dirt or stain gets accumulated, it requires elaborate and harder cleaning efforts.

This cleaning process requires special set of equipment such as the follows.

1. A pool rake

2. Vinyl tile cleaner of mild nature

3. Soft pool cleaning brush

4. Abrasion resistant cloth

For removing the algae, you need to push the scum directly towards the pool main drain.

You can do this using the pool rake.

To clean the dirty and discolored parts, you need to apply the mild vinyl tile cleaner.

Strong cleaning agents should be avoided while cleaning fiberglass pools.

If the stain does not get removed, use the pool brush.

Gently scrub it over the stains. Too much pressure should not be applied.

Lastly, wipe off the stairs with the abrasion-resistant cloth neatly.

Extra care should be taken so that no residue of dirt is left behind on these fiberglass stairs.

3 Methods to Remove Stains from Fiberglass Pool Steps

The stains in the fiberglass pool steps are generally caused by two types of elements such as:

1. Organic Elements: Examples are decomposed leaves, branches, and dirt, etc.

2. Inorganic Elements: Examples are metal (iron, copper, manganese), cobalt, and calcium scaling, etc.

Cleaning Method 1: Using Stain Remover to Clean Harder Organic Stains from Fiberglass Pool Steps

By using a pool brush, you can generally scrub off organic stains from fiberglass pool steps.

But for the stains which are old and stubborn, simply scrubbing them will not be much effective.

In such cases, stain remover should be used.

The benefit of using stain remover is that it softens the stains.

After that, it becomes easy to scrub those hard to remove organic stains.

Here, I highly recommend to use Bosh Chemical Vanish Pool and Spa Stain Remover.

This naturally safe and citrus based stain remover is great for cleaning harder stains from all types of metals, vinyl and fiberglass material.

Cleaning Method 2: Using Stain Remover to Remove Inorganic Metal Stains

For stains that are isolated and smaller in size, rubbing vitamin C tablets can be very effective method.

These tablets also work great in neutralizing chlorine and chloramines from the water.

The tablets should be rubbed directly over the stains to get the best cleaning results.

Now, for bigger and harder to remove stains, you can use the best quality stain remover products from the market.

One such product from the market that I can recommend for you is Natural Chemistry 07400 Stain Remover.

To apply such products, you need to follow the steps mentioned below.

Step 1: First thing is you need to make sure that the level of chlorine should be lowered to 0.0 ppm and the pH level should be fixed at 7.2.

Step 2: The next step is to turn on the pool filter.

Thereafter the stain remover should be added gradually.

One pound of the chemical is sufficient for 10,000 gallons of water.

Step 3: After the application of the chemicals, you need to make sure that the pool remains untouched for at least next 24 hours.

Make the necessary adjustment in the pool water chemicals after the rest period is over.

Step 4: Lastly, apply the sequestering agent to the pool water to get the ideal cleaning results.

Cleaning Method 3: Using Stain Remover to Get Rid of Calcium Scaling

Again, to remove calcium scaling from the fiberglass pool steps, you can use a good quality stain remover product.

Using stain remover is the quickest way to remove calcium scaling from the pool steps.

However, the most advisable way is to follow the process of fiberglass-pool-safe scaling treatment.

You can also take a professional help or guidance if you find calcium scaling removal a bit harder and complicated yourself.

If you want to use a good quality stain remover for removing calcium buildup from the pool steps, then I recommend using Scaletec Plus Descaler and Stain Remover.

With this product at hand, you can easily remove stubborn and hard to remove calcium stains.

This is suitable for all types of pool surfaces, steps and pool tiles.

4 Reasons Why Fiberglass Pool Steps Turn Brown or Orange in Color

The fiberglass may turn brown or orange due to the following four reasons.

Reason 3: Pool Water pH not Within Range

The metals in pool water start to corrode when the pH is low.

It is because water turns acidic with low pH levels.

Thus, it will also cause brownish stains on your pool steps.

So, the pH of pool water should be regularly tested in order to prevent these stains.

Necessary adjustments should be made if required.
