Today, I'm delving into a question that's likely crossed your mind as you've unfolded a fresh set of bedding...should you wash new sheets before using them for the first time?

After all, who doesn't love that luxurious feeling of burying yourself into a brand-new set of sheets straight out of the packaging?

However, it also makes sense to do everything you can to ensure that your organic sheets and bedding are as clean as possible.

In this article, I'll draw on my years of sleep testing expertise to break down why washing new sheets can be beneficial and how to do so properly in an environmentally friendly manner.

Why You Should Wash New Sheets Before Using Them on Your Bed

The Unseen Story of Your Sheets

Straight off the shelf, your sheets might look pristine, but they've been on quite a journey.

They've traveled from factories, warehouses, and retail stores, potentially collecting dust, germs, and chemical residues.

Benefits of Washing New Sheets

Washing new sheets removes harmful chemicals used during manufacturing, like formaldehyde, which can cause skin irritation or respiratory issues.

It also eliminates potential allergens or bacteria, providing a clean and healthy sleep environment.

Even the most eco-friendly and sustainable sheets might have collected dirt and allergens along the way.

How to Wash New Bedding Items

Choosing the Right Detergent

Opt for eco-friendly detergents that are free from harsh chemicals, fragrances, additives, and dyes.

These detergents are gentle on your sheets and kind to our waterways.

Instructions for Washing Sheets

For best results (and to prolong the life of your sheets), follow the care instructions on the label. But, as a general guide, use warm water (not hot) and a gentle cycle.

I recommend keeping your sheets separate from other items during the first few washes to ensure they retain their pristine appearance. After two or three washes, feel free to safely mix them with other laundry without the risk of damage.

Alternatively, for added convenience, you can establish a routine of washing your sheets with the rest of your bedding.

Other things you might want to consider using when washing your new sheets include:

  • Baking Soda: Add one cup of baking soda to your eco-friendly detergent to boost the cleaning power. This can also be an excellent way to make old sheets white again.
  • Vinegar: Vinegar is an effective natural fabric softener. Just add one cup of white vinegar to the fabric softener compartment of your washing machine and let it do its thing during the rinse cycle. Adding vinegar to your wash also enhances its germ-killing power, ensuring maximum effectiveness.

Drying Techniques for New Sheets

Air-drying is the most eco-friendly method.

If you must use a dryer, choose a low-heat setting to prevent shrinkage. Also, using good-quality natural dryer balls will help speed up the drying time and reduce electricity use.

Folding and Storage

If you're not going to use your sheet again immediately (for example, if you have multiple sets that you rotate), it's important to fold them neatly and store them in a cool, dry place.

By taking the time to fold them properly, you minimize the chances of creases and wrinkles, allowing you to enjoy a crisp and inviting bed when you next use them.

When you store your sheets in a cool, dry place, you create an environment that discourages the growth of mildew and molds.

For long-term storage, consider using protective bags to keep the material clean and fresh.

Types of Sheets

There are numerous types of sheets, each with different properties and care needs:

  • Cotton: Cotton sheets come in many different weaves and thread counts. It's important to steer clear of traditional cotton if possible and prioritize organic cotton.
  • Cotton Mix: Made from A blend of fabrics (usually cotton and polyester), cotton mix sheets are less expensive than 100% cotton but not as breathable and may come with more hidden nasties.
  • Synthetic: Synthetic blends are usually made from polyester or other synthetic fibers. They are typically at the budget end of the price range and are not considered eco-friendly or sustainable.
  • Flannel: Flannel sheets are made from a brushed cotton fabric and come in different weights. They tend to be thicker than other types of bedding, making them warm and cozy during the winter months.
  • Linen: A sustainable fabric made from natural flax fibers spun into yarns. It's breathable, strong, hypoallergenic, and durable. Linen sheets are a great choice if you're looking for a hard-wearing and sustainable option.
  • Silk: Silk sheets are luxurious and very soft to the touch. They tend to be more expensive than other types of bedding but can last for years if properly cared for.
  • Bamboo: When made ethically and using a closed-loop process, bamboo sheets and bedding sets are a natural and renewable option. They're also durable, hypoallergenic, and breathable, making them perfect if you have allergies or sleep hot.
  • Percale:  As mentioned in my eco-friendly bedding brands article, percale is a favorite of mine. It's a lightweight, crisp fabric with a tight weave that helps keep you cool during the summer months.

Remember to always check the care label on your sheets to ensure you use the most appropriate washing method.

Certifications that Help Reduce Exposure to Toxins

Given that one of the primary purposes of washing new bed sheets is to eliminate potential toxins and irritants, it's advisable to purchase sheets that are as pure and free from toxins as possible.

One way to ensure that your brand new sheets are genuinely non-toxic (and you've not fallen foul of greenwashing) is to look for the following trusted and respected third-party certifications:

  • Global Organic Textile Standard (GOTS): This is one of the leading textile processing standards for organic fibers. It includes ecological and social criteria backed by independent certification of the entire textile supply chain. A product with the GOTS label must contain a minimum of 95% certified organic fibers.
  • OEKO-TEX® Standard 100: This is a worldwide, consistent, independent testing and certification system for raw, semi-finished, and finished textile products at all processing levels. Products tested for harmful substances and deemed harmless in human ecological terms carry the STANDARD 100 label.
  • MADE SAFE®: This certification ensures that items are made with safe ingredients not known or suspected to harm human health.
  • Fair Trade Certification: While this doesn't directly relate to toxins, Fair Trade certification ensures that products are made in safe working conditions where farmers and producers receive a fair price and have a voice in how their workplace is run.
  • USDA Organic: This certification applies to fiber crops like cotton and linen. It ensures that the plants are grown without synthetic fertilizers, pesticides, and herbicides.

Frequently Asked Questions

What happens if you don't wash sheets before using them?

If you don't wash sheets for the first time, they might not be as soft and comfortable as they're meant to be. Plus, if there is any chemical residue, dust mites, or bacteria left from the manufacturing process, it can remain on your sheets and cause skin irritation or allergic reactions.

How often should you wash bed sheets?

According to Cleveland Clinic, skin expert Alok Vij, MD, recommends washing your sheets at least every two weeks.

Can I machine wash 'dry clean only' items?

No, you should not machine wash dry clean only items. The best way to clean these items is to have them professionally dry-cleaned.

What is the best thread count for sheets?

The best thread count for sheets depends on personal preference. Generally, anything between 200 and 400 is considered a good mid-range option that provides a nice balance of softness and breathability. Higher thread counts tend to feel softer but are usually more expensive. Lower thread counts often become stiffer over time.

Do new sheets have formaldehyde?

Bed sheets marketed as 'wrinkle-free,' 'no wrinkle,' or 'no iron' often have a formaldehyde finish. This finish can lead to various discomforts, such as a sore throat and teary eyes. Additionally, there have been studies linking formaldehyde exposure to cancer.

Can I wash my new sheet set in cold water?

It's always a good idea to follow the manufacturer's recommendations when washing your sheets. However, washing them in cold water is better than not washing them at all.

Final Word

So, while it's not essential to wash your new sheets before sleeping on them, it's highly recommended (especially if you have allergies or sensitive skin).

This is because new bedding and clothing often contain chemical residues, dirt, bacteria, etc., which can be potentially harmful to your skin.

By washing them before use, you can effectively remove these substances and ensure a safer and more pleasant sleeping experience.

Also, to maintain cleanliness and hygiene, it's advisable to wash sheets at least every two weeks. This helps to eliminate accumulated dirt, sweat, and allergens, keeping the sheets clean and comfortable.

By following the simple practices mentioned in this article, you'll not only promote a good night's sleep but also support your overall well-being.

And don't just limit it to sheets and bedding.

To be on the safe side, I recommend washing anything you buy new (or second-hand) that is going to come into regular contact with your skin (such as duvet covers and clothing, for example).

Sleep tight and stay healthy!
