How to Remove Atomic number 26 (Rust) Stains from a Pool

There are several methods that can be used to remove rust stains from pools and they vary based on the type of puddle surface and the extent of staining. The fix could exist every bit simple as using vitamin c tablets to remove small-scale spot staining or as complex equally draining the puddle and acid washing with a dilute concentration of hydrochloric acid.

Let's Jump In and Have a Look at Some Ways to Get Rid of those Ugly Iron Stains.

Here'south a quick summary of the dissimilar methods available and what they're best for.

Rust Stain Removal Method	Pool  Type	Best for Stain Blazon
Vitamin C tablets (Ascorbic Acid)	Plaster, Vinyl, and Fiberglass Pools	Small rust stains are caused past metal objects in the pool such as hairpins.
Stain Eraser Tool
Ascorbic Acid Pulverization	Plaster, Vinyl, and Fiberglass pools.	Multiple or larger stains. Use when in that location are too many stains use Vitamin C tablets.
Muriatic (Hydrochloric) Acid	Plaster pools	Pocket-sized and large stains that are unable to be removed using vitamin C or ascorbic acid powder.

one. Use Vitamin C (Ascorbic Acid)

Suitable for: Plaster, Vinyl, and Fiberglass Pools

Vitamin C contains ascorbic acid and is an easy way to handle small-scale stains such as those caused by metallic objects falling in the water or fertilizer being over broadcast in the pool.

OK, now that you know I have damaged my ain plaster before, allow's look at how to spot and treat a few rust stains.

Sock Method

• Add together about xv to 20 vitamin c tables to an former sock and identify the sock on the stain.
• Leave the sock for a infinitesimal or rub the stain with it and then brush to remove the stain.
• If it isn't gone, reapply the sock for another infinitesimal and echo rubbing and bruising.
• Do this until the stain is totally removed and be certain to do a final brush of the area to disperse the vitamin c equally it'southward acidic.
• Don't worry most the iron ions redepositing as long as you take less than 0.two ppm iron content in the water. The amount of fe from small stains such as a hairpin or a spiral isn't plenty to redeposit into a stain once lifted.

Crushed Tablets/Powder

• Put the tablets in a nothing lock bag and crush them to make a powder.
• Sprinkle the powder over the stained area and allow it sit for almost 2 minutes before brushing.
• If the surface area is medium-sized and y'all need more than than a couple of bottles on tablets it may be more economical to purchase ascorbic acrid pulverization or a stain removal product containing ascorbic acid. Meet below.

9. Return the filter to "filtration mode," or put your cartridge filters back in, and permit the pump run for 24 hours.
x. If yous see stains forming again when you lot offset raising your chlorine, make certain the pH is vii.two and add some more sequestering agent.
11. Your water will likely be cloudy, but information technology will clear with time every bit long every bit you exit the pump running 24×7.
12. Add CuLator co-ordinate to the manufacturer's instructions for your pool volume in order to fully remove the metal ions as the sequestering agent disappears over the next 30 days. Alternatively, you tin can too bleed and replace some of the pool water. This will dilute the metal content.

4. Muriatic (Hydrochloric) Acrid

Suitable for: Plaster pools.

Muriatic acid is a nifty way to remove iron stains, but it tin also stain decks if spilled and it can ruin puddle surfaces if used in besides high of a concentration. Remember to ever vesture protective gloves and eyewear when handling acrid to avoid personal injury.

One word of caution here, there are many sites and social media posts that recommend pouring hydrochloric acid downwards a PVC pipe that's positioned direct over the rust stain – DON'T Exercise THAT unless you are experienced with this method.

Trust me from experience, if you don't know what you are doing you lot volition erode your pool plaster.

Now that we accept covered the safety precautions and hazards, let's wait at how to safely use muriatic acrid for removing stains.

Note that muriatic acrid tin be used for both small stains and big or pervasive staining.

Steps for Using Muriatic Acid

For Small Stains:

1. Dilute the acrid 2 parts water to 1 part acid, to brainstorm with and if the stain isn't coming upward then y'all tin can move from one function acid to ane office water. Call back to ever "add together acrid" to water and non the other fashion around as calculation h2o to acid causes a trigger-happy reaction.
2. Carefully pour the solution at the end of the pipe and then brush with a pool brush to distribute the acrid and lift the stain. If it doesn't come up at first, try more acrid and/or increase the concentration.

Tip: There are tools such as the Purity Puddle Stain Remover that are self-contained and make the application of acid (both liquid and powder) much easier, and frankly work better than the PVC piping and brush method.

How the agent works	Ane-to-i bonding of ions. Binds to metal ions to prevent them from undergoing chemic reactions such as oxidation which causes staining.	Many too many bonding of ions forms a larger complex molecule that can be filtered out.	Bonds with metal ions and traps them for complete removal.
When to employ	New puddle startups to preclude staining Fresh stains Trace level of metals	New puddle startups to preclude staining Well water fills or refills Higher level of metal content	New pool startups to forestall staining Clearwater from oxidized copper-based algaecide and oxidized iron Well water fills or refills Higher level of metal content
Pros	Easy to use Quick handling for preventing staining without waiting for full removal	Easy to use Quick treatment to foreclose staining without waiting for total removal	Completely removes metallic ions
Cons	Does not remove metal ions Requires weekly maintenance doses	Does not remove metallic ions Requires weekly maintenance doses	Tin can take time to fully remove metal ions
