DIY Swim Spray to Neutralize Chlorine

This DIY swim spray helps remove chlorine from skin and hair after swimming. Made with vitamin C, this simple after-swim spray neutralizes chlorine quickly and helps reduce dryness, irritation, and that lingering pool smell.

If you or your kids spend time in chlorinated pools, this easy homemade chlorine neutralizing spray can help protect skin and hair with just a few inexpensive ingredients.

Summer is a time for fun in the sun and fun in the water, which can mean a lot of time at the pool. However, it also means more exposure to chlorine, which isn't so great.

Thankfully, with this easy DIY Swim Spray, you can neutralize some of that chlorine and give yourself more peace of mind regarding your family's health.

We live by a community pool and our boys took swim lessons there for a few years. They were required to shower after leaving the pool, and while I was glad about that, I didn't want my boys using the toxic shampoo at the pool, so I sent them with safer options.

However, I have noticed that the chlorine smell still lingered on them, even after their sometimes prolific showering.

I found out that shampoo and other cleaning products don't wash chlorine off the skin, and that's when we started making this super easy homemade swim spray.

Where Chlorine Exposure Happens (Pools, Showers, and Tap Water)

Chlorine is something that we're all exposed to. It's in our tap water, in bleach used for disinfecting around the home by some, and of course it's used heavily in most swimming pools. If you have the privilege of frequenting a salt pool, your exposure to chlorine can be less, but even that's not guaranteed to be the case.

Clearly, it has its place. I mean, who wants to swim in a pool where some kid might have done something, plus there are all kinds of other things in our water that we don't want on our body or in our drinking water.

However, chlorine in and of itself has health risks.

We all know how when you spend too much time in a chlorinated pool, you tend to have some irritation like red eyes and possibly a rash.

However, the health implications go beyond that.

Health Concerns Related to Chlorine Exposure

Chlorine can:

– dry out hair
– cause breathing problems
– cause dental erosion
– dry out skin
– cause stillbirths (from byproducts of chlorinated water)
– cause bladder cancer
– lead to rectal cancer
– cause cardiovascular disease
– cause allergies due to sensitization

How This DIY Swim Spray Works

• Vitamin C neutralizes chlorine on skin and hair
• Helps reduce chlorine smell after swimming
• May help prevent dry hair and skin from pool exposure
• Takes less than 2 minutes to make

How Vitamin C Neutralizes Chlorine

Vitamin C neutralizes chlorine by converting it to other things via a chemical reaction. In this case, vitamin C donates electrons to chlorine compounds, reducing them into harmless substances like hydrochloric acid and water. Then the vitamin C is oxidized into dehydroascorbic acid (DHA). This chemical reaction is called oxidation-reduction (redox) and it's a very fast and effective reaction.

Vitamin C is used to neutralize chlorine in water systems. It's safe for aquatic animals, and it's also safe for you to use on your skin and hair.

While it won't address chlorine that's been inhaled or absorbed beyond the skin, it can certainly help remove some of the problem.

What This Spray Can and Can’t Do

This DIY swim spray can help neutralize chlorine on the surface of the skin and hair after swimming. However, it’s important to know that it isn’t a complete solution to chlorine exposure.

Chlorine exposure in pools happens through:

• breathing chlorinated air above the water
• absorption through the skin while swimming
• exposure to chlorine byproducts formed in pool water

This spray simply helps remove some of the chlorine that remains on the skin and hair after you leave the pool. While that can help reduce irritation, dryness, chlorine odor, and addresses some of the toxicity issues involved, it doesn’t prevent all potential exposure.

Showering, limiting time in heavily chlorinated pools, and swimming in well-maintained pools are other things you can do to reduce chlorine exposure.

Not all products actually remove chlorine from skin and hair. Many soaps only wash the surface but don’t neutralize chlorine. Here's how common chlorine removal methods compare.

As you can see, most soaps and shampoos don’t actually remove chlorine—they mainly clean oils. Vitamin C works differently by chemically neutralizing chlorine.

Does Showering Remove Chlorine?

Showering alone does not fully remove chlorine from skin and hair. Soap and shampoo mostly remove oils and dirt, but chlorine binds to proteins in hair and skin. Neutralizing it with vitamin C is needed to help remove chlorine more effectively.

Supplies for This Spray

Vitamin C

Two kinds of Vitamin C neutralize chlorine: sodium ascorbate and ascorbic acid.

While either version of vitamin C will work for this after swim spray, there are several reasons why sodium ascorbate is the better choice here.

First, ascorbic acid is more acidic, so it can lead to irritation, especially when used often.

Secondly, sodium ascorbate dissolves much more readily than ascorbic acid so it's a bit easier to use.

Bottles

Plastic is the best choice to prevent any breakage around the pool area where bare feet could end up with painful slivers in them, but make sure to choose a high-quality plastic bottle so that the optional essential oils and vitamin C won't be likely to cause leaching of the plastic.

Light will cause the vitamin C to degrade so tinted bottles are best.

Tips for Using Vitamin C Swim Spray

• Shake Before Using: Ensures ingredients are well-mixed.
• Make Small Batches: With time, the solution will degrade, so it's best to only make the amount you will likely use within a few days to a week.

Storage

• Use Dark Glass or Plastic Bottles: Again, this will protect the solution from exposure to light which causes it to lose effectiveness.
• Store in a Cool, Dark Place: Keep away from heat and sunlight, again to help it not lose effectiveness. Storing this spray in a dark bottle in the fridge is a good option.

How to Use This DIY Swim Spray

1. Spray generously on skin and hair after leaving the pool.
2. Let sit for 30–60 seconds so the vitamin C can neutralize chlorine.
3. Rinse with fresh water or shower.
4. Repeat if chlorine smell remains.

Optional: spray directly onto hair before rinsing to help reduce chlorine damage.

FAQ

Does vitamin C really remove chlorine?
Yes. Vitamin C (ascorbic acid or sodium ascorbate) neutralizes chlorine through a redox reaction that converts chlorine into harmless compounds.

Can I use this spray on hair?
Yes. It can be sprayed directly on hair before rinsing to help reduce chlorine damage and dryness.

Is this safe for kids?
Yes. The ingredients are very gentle, but you should avoid spraying directly into the eyes.

How long does vitamin C spray last?
Vitamin C breaks down when exposed to light and air. For best effectiveness, make small batches and use within about a week.
