Everything You Didn’t Know About Laundry Detergents (But Should!)

Feb 1, 2025Tips, Laundry Service0 comments

See those laundry detergents on store shelves? Some brands are even advertised on TV with flashy commercials promising brighter whites, fresher scents, and unbeatable stain removal. But beyond the bold claims and colorful packaging, how much do you really know about what’s inside that bottle?

If you’re like most people who just grab a bottle off the shelf without thinking twice, now’s the time to take a closer look. There are eco-friendly formulas, fragrance-free options for sensitive skin, and high-efficiency detergents designed for modern washing machines—but how do you know which one is right for you?

To help you decide, let’s break down in this post everything you didn’t know about laundry detergents but should!

1 | Did You Know: More Detergent Doesn’t Mean Cleaner Clothes?

In reality, too much detergent can leave a soapy residue on fabrics, clog your washing machine, and even make your clothes feel stiff or dingy over time. Here’s why:

  • Detergent needs water to rinse away completely. When you overload your washer with soap, your machine can’t fully rinse it out. That leftover detergent sticks to fabrics, making them stiff, dull, and more likely to trap odors.
  • Too many suds = trapped dirt. High-efficiency (HE) washers are designed to use less water, so excessive detergent creates too many suds. Those bubbles don’t lift away dirt properly, causing grime to settle back onto your clothes.
  • Residue buildup can irritate the skin. If you or someone in your household has sensitive skin, extra detergent can be a hidden culprit. It lingers in fabrics and can cause itchiness, rashes, or allergic reactions.

If you suspect detergent overload, run an extra rinse cycle to remove lingering soap and consider using a washing machine cleaner once a month to keep your appliance fresh.

How to Measure the Right Amount of Detergent:

  • HE Machines – Use 1-2 tablespoons of liquid detergent per load.
  • Standard Machines – Use ¼ to ½ cup, depending on the load size and how dirty your laundry is.
  • Pods – Stick to one pod per load unless washing a heavy or oversized load.
  • For Small Loads – Use half the recommended amount to avoid excess suds.

2 | Did You Know: Powder, Liquid, and Pods Work Differently?

Choosing the right type of detergent can make a big difference in how clean your clothes get. Liquid detergent is great for pretreating stains, powder is powerful against dirt, and pods are all about convenience. The best choice depends on your laundry habits, washing machine type, and water temperature.

1. Powder Detergent: Best for Heavy-duty Cleaning

Powder detergents contain powerful cleaning agents that work great on tough stains like mud, clay, and grass. They’re especially effective in warm or hot water since they need heat to dissolve fully.

  • Best for: Large loads, heavily soiled clothes, and hard water areas.
  • Watch out for: If used in cold water, the powder may not dissolve completely, leaving behind residue on clothes.

2. Liquid Detergent: Great for Spot Treating and Cold Washes

Liquid detergent is already dissolved, making it a go-to option for washing in cold water (which helps prevent shrinkage and fading). It’s also easier to pretreat stains—just apply a little directly to the spot before washing.

  • Best for: Cold washes, grease or oil stains, and pretreating clothes.
  • Watch out for: It’s easy to over pour, leading to excess suds and buildup in your washing machine.

3. Laundry Pods: Convenient but Costly

Pods are pre-measured, making them super convenient—just toss one in, and you’re good to go. They work well in both standard and HE machines, but they tend to be pricier per load. Plus, since they contain concentrated detergent, they may not fully dissolve in short or cold cycles.

  • Best for: Convenience, mess-free measuring, and HE machines.
  • Watch out for: Can be expensive, and if they don’t dissolve properly, they might leave a sticky residue on clothes.

So, Which One Should You Use?

  • If you need deep cleaning power and don’t mind warm washes, go for powder.
  • For an all-around detergent that works at any temperature, liquid is your best bet.
  • If you value convenience and hate measuring, pods are a hassle-free option.

3 | Did You Know: Fabric Softener Isn’t Always Necessary?


Most liquid fabric softeners contain silicones and petroleum-based ingredients that coat fabric fibers to make them feel softer. But over time, that coating builds up, making towels less absorbent, workout clothes less breathable, and even reducing the effectiveness of detergent.

Fabric Softener Is Not Safe for All Fabrics

Some fabrics just don’t mix well with fabric softener. Avoid using it on:

  • Towels – It reduces their ability to absorb water.
  • Athleticwear – It clogs moisture-wicking fabrics, making them less effective.
  • Flame-resistant clothing (like children’s pajamas) – It can interfere with the fire retardant coating.
  • Microfiber and synthetic fabrics – It weakens their fibers over time.

What to Use Instead

If you love the idea of softer laundry but want to avoid the downsides, try these alternatives:

  • White vinegar – A natural softener that helps remove detergent buildup. Add ½ cup to the rinse cycle.
  • Wool dryer balls – They reduce static, speed up drying time, and keep clothes feeling soft without chemicals.
  • Baking soda – Helps maintain fabric freshness and softness when added to the wash cycle.

4 | Did You Know: Some Laundry Detergent Formulation Can Cause Skin Allergies?

If your skin feels itchy, irritated, or breaks out in rashes after wearing freshly washed clothes, your laundry detergent could be to blame. Many commercial detergents contain chemicals, fragrances, and preservatives that can trigger allergic reactions or skin sensitivities—especially for those with conditions like eczema or contact dermatitis. And because detergent residue can linger on fabric, your skin is constantly exposed to potential irritants.

How to Avoid Skin Irritation:

  • Choose hypoallergenic, fragrance-free detergents with fewer harsh chemicals.
  • Avoid detergents with optical brighteners, which can leave a residue that irritates the skin.
  • Rinse clothes thoroughly—especially if you tend to use more detergent than needed.
  • If switching detergents, wash one load at a time and see if symptoms improve before making it your go-to.

How to Tell If Your Detergent Is Causing a Reaction

If you’re experiencing any of the following symptoms, your detergent could be the issue:

  • Red, itchy, or inflamed skin, especially where clothing touches (waistbands, cuffs, underarms)
  • Unexplained rashes or dry patches that don’t improve with lotion
  • Irritation that worsens after wearing freshly washed clothes

One way to check? Try re-washing your clothes in a fragrance-free, hypoallergenic detergent and skip fabric softener. If your symptoms improve, you’ve likely found the cause.

5 | Did You Know: Eco-friendly Detergents Work—But Differently?

Most people assume eco-friendly detergents aren’t as powerful as traditional detergents. After all, how could a plant-based formula possibly tackle tough stains like coffee, grease, or sweat as well as chemical-heavy detergents? The truth is, they do work—but in a completely different way.

What to Expect When Using Eco-friendly Detergents

Switching to an eco-friendly detergent means adjusting your laundry habits slightly. Here’s what you need to know:

  • They may take longer to work – Enzymes need time to break down stains, so letting clothes soak before washing can improve results.
  • They don’t produce a lot of suds – Unlike conventional detergents that foam up, plant-based formulas clean without excess bubbles. That’s actually a good thing—more suds don’t mean a better clean!
  • They’re safe for sensitive skin – Free from synthetic dyes and fragrances, eco-friendly detergents are less likely to trigger skin irritation.
  • They work better in warm water – Some enzyme-based formulas perform best in moderate to warm water since heat helps activate their stain-fighting power.

For customers using a laundry Pickup and Delivery Service or commercial laundry service, ask if they offer eco-friendly detergent options to make your laundry routine more sustainable.
