How to Properly Use a Magic Eraser in a Pool

How to Properly Use a Magic Eraser in a Pool

While magic eraser in pool certainly have benefits for pool cleaning, they do need to be used correctly. Here are some tips on the proper techniques:

Prep the Surface First

Before tackling stains with the magic eraser, make sure to scrub the pool surfaces with a brush and your regular pool detergent first. This will help lift off loose dirt so the eraser can target the remaining grime.

Wet the Sponge

Thoroughly wet the magic eraser until expanded before wiping down the pool surface. This allows the melamine foam to soften and lift away buildup more effectively. Avoid using the sponge dry, as this can be too abrasive.

Use a Light Touch

When wiping with the magic eraser, use light, gentle motions. Don’t aggressively scrub, as the melamine foam does the cleaning work for you. Let the sponge do the job.

Target Small Sections

Work in smaller sections when using a magic eraser on the pool. The sponges are small, so tackle just a few square feet at a time for best results.

Rinse Frequently

Rinse the magic eraser sponge often as you clean. This keeps it free of dirt and debris so it can continue effectively wiping away stains.

Use Sparingly on Vinyl

Magic erasers can be used on vinyl liner pools but use gently and sparingly. Aggressive scrubbing can damage vinyl over time.

Follow these tips, and a magic eraser can be a handy, safe tool for tackling your pool cleaning needs. Just don’t overuse it or get too aggressive!

Areas of the Pool Magic Erasers Clean Well

There are certain parts of your pool where a magic eraser in pool really shines at removing built-up gunk and stains:

Pool Tile

The tile surfaces around the waterline and decorative insets can easily get a buildup of calcium, rust, oil, and dirt stains. A magic eraser makes quick work of this grimy tile band.

Steps and Benches

Pool steps and benches with tile surfaces often get a dingy look from feet traffic and body oils. Magic erasers will have them looking fresh and clean again.

Fiberglass Surfaces

For fiberglass pool surfaces, a magic eraser wipes away sticky residue, suntan lotion buildup, random rust stains, and other dirt.

Under the Decking

Ground-in dirt and grit often collect on the pool walls and floor under the deck area. Reach a magic eraser underneath to remove this unsightly grime.

Waterline Ring

That notorious ring around the waterline caused by oils, lotions, and dirt is no match for the cleaning power of the magic eraser!

Areas to Avoid Using a Magic Eraser

While a magic eraser works great for cleaning many pool surfaces, there are certain areas and materials you’ll want to avoid using it on:

Areas to Avoid Using a Magic Eraser

Vinyl Liners

Magic erasers can damage vinyl pool liners if you aggressively scrub. Use sparingly and gently on vinyl.

Newer Tile Grout

Aggressive magic eraser scrubbing can prematurely wear away newer grout before it’s had a chance to fully cure and harden.

Polished Plaster Finishes

Avoid using magic erasers on softer polished plaster pool finishes, as the melamine foam can damage the surface.

Areas Near Decals and Inlays

Don’t use a magic eraser too close to vinyl decals or tile inlays, as aggressive scrubbing may loosen edges.

Areas With Calcium Deposits

Magic erasers won’t effectively remove mineral deposits and etched calcium. A calcium remover product is a better option.

Being cautious around these materials and surfaces will ensure your magic eraser doesn’t cause any damage. Check its effects in an inconspicuous spot first if unsure.

Can You Use a Magic Eraser in Other Parts of the Pool?

In addition to using magic erasers on submerged pool surfaces, you can also use them in certain areas outside the water:

Pool Decking

For concrete, stamped concrete, and paver pool decks, a magic eraser makes quick work of ground-in dirt, moss and algae growth in porous areas, rust stains from metal furniture, and weathered areas. Just wet, wipe and rinse.

Pool Tile Coping

Magic erasers shine at removing grime buildup, suntan lotion residues, and rust stains from pool tile coping without damaging the finish.

Pool Ladders

Plastic and metal pool ladders often fall victim to mold and mildew growth along with rust stains. Use a magic eraser wet to remove buildup and restore ladders to like-new.

Pool Covers and Blankets

Vinyl, plastic and fiberglass automatic pool covers can get grungy looking from debris and dirt that collect on top. A magic eraser is ideal for wiping down pool covers and blankets.

Wherever you have a grimy pool surface, there’s a good chance a magic eraser can restore it to clean again!

Tips for Best Results Using Magic Erasers

Tips for Best Results Using Magic Erasers

To get the most out of your magic erasers for pool cleaning, follow these handy tips:

  • Start with fresh, new magic eraser sponges. Old, worn ones won’t clean as effectively.
  • For tough stain removal, try pre-treating with a pool tile cleaner before using the magic eraser.
  • Use short, light, circular scrubbing motions, not aggressive back-and-forth rubbing.
  • Rinse the sponge often to prevent dirt buildup that can scratch surfaces.
  • Use gentle pressure – let the melamine foam do the work.
  • Target small sections at a time for thorough cleaning.
  • To clean metal surfaces, use immediately – don’t let eraser sit on metal to prevent oxidation.
  • Wear gloves to protect hands from extended water and chemical exposure.
  • When finished, discard worn eraser sponges so they don’t transfer grime to other areas later.

Are Magic Erasers Safe for Pools?

When used properly, magic erasers are considered safe, effective cleaners for pools. However, there are a few precautions to keep in mind:

  • Rinse surfaces thoroughly after use to remove any foam residue.
  • Discard eraser pieces in trash after use so they aren’t accidentally left in the pool.
  • Supervise children if allowing them to help clean the pool with magic erasers.
  • Read product instructions carefully in case certain brands have specific cautions or warnings.

As long as you follow the proper techniques, exercise reasonable caution, and don’t overuse magic erasers, they pose very little safety risk to your pool. Their cleaning benefits will simply outweigh any small concerns.

Can You Use Other Cleaning Products With Magic Erasers?

For the most part, no other cleaning products are needed when using a magic eraser in the pool. The melamine foam does the work all on its own with just water.

However, if dealing with especially tough stains, you can pre-treat the area to boost the cleaning action:

  • Pool tile cleaners help break down stubborn buildup.
  • Rust removers dissolve oxidation on metal surfaces.
  • Calcium stain cleaners dissolve mineral deposits.

In most cases though, the magic eraser alone will tackle common pool grime. Avoid using aggressive and corrosive cleansers that could interact with the melamine foam and scratch surfaces.

Magic erasers have earned their popularity among pool owners because they truly do clean better and easier than many traditional pool scrubbing tools and ingredients.

Their melamine foam structure gives them a unique cleaning advantage. Here’s how they measure up:

  • Clean more thoroughly than towel rubbing or even pressure washing.
  • Remove grime that evades other manual scrubbing sponges.
  • Provide chemical-free cleaning unlike bleach, muriatic acid or chlorine.
  • Won’t mar or etch surfaces like some abrasive pads can.
