When to Use Hot Water for Laundry, Reddit? The Definitive Guide

Hot water in laundry: it’s the age-old debate that has plagued laundry rooms and sparked heated discussions on forums like Reddit for years. But fear not, dear reader, for I, your laundry whisperer, am here to finally settle the score. So, when should you use hot water for laundry? Primarily, use hot water for whites that are heavily soiled, particularly with oil-based stains, and for items that need sanitizing, such as bedding after an illness or heavily soiled towels. Hot water is a powerful cleaning agent but should be used judiciously, considering its potential to fade colors and damage certain fabrics. Now, let’s delve into the nitty-gritty, shall we?

The Power of Hot Water: Pros and Cons

Hot water is a workhorse in the laundry room, but understanding its strengths and weaknesses is crucial.

The Upsides:

Stain Removal: Hot water excels at dissolving and removing stubborn stains, especially those of an oily or greasy nature. Think food spills, automotive grime, or persistent mud.
Sanitization: When you need to kill germs and bacteria, hot water is your ally. This is vital for items like underwear, bedding after someone’s been sick, or heavily used towels. A temperature of at least 140°F (60°C) is generally recommended for effective sanitization.
Brightening Whites: Hot water helps keep white fabrics looking their best by lifting embedded dirt and grime that can cause yellowing or dullness.
Dissolving Detergent: Hot water helps detergent dissolve more effectively, ensuring it distributes evenly throughout the wash and maximizes its cleaning power.

The Downsides:

Color Fading: This is the biggest risk. Hot water can cause dyes to bleed and fade, especially in brightly colored or delicate fabrics.
Shrinkage: Natural fibers like cotton and wool are particularly susceptible to shrinkage in hot water.
Energy Consumption: Heating water consumes a significant amount of energy, making hot water washes more expensive and environmentally taxing.
Setting Stains: Ironically, hot water can actually set certain stains, particularly protein-based stains like blood or egg.

Decoding Your Laundry: Knowing When to Heat Up

So, how do you navigate this laundry labyrinth? Here’s a breakdown of when to consider using hot water:

Ideal Scenarios for Hot Water:

Heavily Soiled Whites: Think work clothes caked in mud, heavily stained kitchen towels, or white athletic socks after a marathon.
Items Requiring Sanitization: Bedding used during an illness (flu, cold, etc.), reusable diapers, or heavily soiled towels that may harbor bacteria.
Oil-Based Stains: Grease stains on clothing, cooking oil spills on linens, or automotive grease on work clothes.

When to Say “No” to Hot Water:

Brightly Colored Clothes: Unless the care label specifically recommends hot water, err on the side of caution and use cold or warm water to prevent fading.
Delicate Fabrics: Silk, lace, wool, and other delicate fabrics are easily damaged by hot water.
Protein-Based Stains: Blood, egg, milk, and other protein-based stains should always be treated with cold water first. Hot water will cook the protein and make the stain even harder to remove.
Anything You’re Unsure About: When in doubt, check the care label! The manufacturer knows best.

Reading the Tea Leaves: Interpreting Care Labels

Your clothing’s care label is your laundry oracle. Pay close attention to the symbols and instructions. A washing machine symbol with a dot inside indicates the recommended water temperature:

One dot: Cold water
Two dots: Warm water
Three dots: Hot water

If there’s a washing machine symbol with an “X” through it, the garment should be hand-washed or dry-cleaned.

Detergent Matters: Choosing the Right Partner for Hot Water

Using a high-quality detergent specifically formulated for hot water is crucial. Look for detergents that contain enzymes that can break down stains and surfactants that effectively lift dirt and grime. Powdered detergents often dissolve better in hot water than liquid detergents, but this can vary by brand.

Frequently Asked Questions (FAQs)

Here are some common laundry conundrums, addressed with expert precision:

Does hot water always kill bacteria? No, not necessarily. To effectively sanitize, the water temperature needs to reach at least 140°F (60°C) and be maintained for a certain period. Many home washing machines don’t reach this temperature, so consider using a laundry sanitizer in addition to hot water for truly effective sanitization.
Can I use hot water to pre-treat stains? Yes, but with caution! For oil-based stains, a short soak in hot water with detergent can help loosen the stain before washing. However, avoid hot water for protein-based stains, as it will set them.
Is it safe to wash all my whites in hot water? Not always. While hot water is great for heavily soiled whites, delicate white fabrics like lace or silk should be washed in cold or warm water to prevent damage.
Will hot water shrink my clothes? It’s possible, especially with natural fibers like cotton, wool, and linen. Minimize shrinkage by using a delicate cycle and avoiding high heat in the dryer.
Can I use hot water for my baby’s clothes? Yes, if the clothes are heavily soiled or require sanitization. However, always check the care label and use a gentle, fragrance-free detergent.
Is it okay to mix colors and whites in hot water? Absolutely not! This is a recipe for disaster. Colors will likely bleed, ruining your white garments. Always separate your laundry into whites, lights, and darks.
Does using hot water mean I can use less detergent? No. Follow the detergent manufacturer’s instructions for the recommended amount based on the load size and soil level.
How can I save energy when using hot water for laundry? If your washing machine has an energy-saving setting, use it. This will reduce the amount of hot water used and shorten the wash cycle. Also, consider using cold water for most of your laundry, reserving hot water only for heavily soiled or items requiring sanitization.
What if my washing machine doesn’t have a temperature setting? Most washing machines have temperature settings, even if they’re not explicitly labeled. Check your owner’s manual for instructions on how to adjust the water temperature.
Can I use hot water to wash my reusable shopping bags? It depends on the material. Canvas bags can usually be washed in hot water, but always check the care label. Plastic or nylon bags should be washed in cold water to prevent damage.
What about hand-washing? Should I use hot water then? Not usually. Hand-washing is generally reserved for delicate items, which should be washed in cool or lukewarm water.
I accidentally washed a colored garment in hot water and it bled. Can I save it? Act fast! Immediately rewash the garment in cold water with a color-safe bleach or a color run remover product. This may help to lift the dye and prevent it from setting further. However, there’s no guarantee of success.

The Final Spin: Mastering the Hot Water Wash

Ultimately, knowing when to use hot water for laundry comes down to understanding the fabric, the type of stain, and the desired outcome. By following these guidelines and paying attention to care labels, you can harness the power of hot water to achieve sparkling clean and sanitized laundry, while minimizing the risk of damage and fading. Happy laundering!
