Pillow Protector is the unsung heroes of our bedding. While we often pay attention to our pillowcases and sheets, protectors for pillow serve as the first line of defense against sweat, dust mites, allergens, and accidental spills. They not only help keep your pillow cleaner and more hygienic but also significantly extend its lifespan. Whether you're using a standard cotton protector, a waterproof variant, or a hypoallergenic model, proper maintenance is essential to ensure it does its job well.

Despite being relatively low-maintenance, pillow cases still require regular cleaning and care to perform at their best. Washing them improperly can lead to shrinkage, fabric degradation, or loss of protective qualities. On the other hand, proper upkeep keeps them fresh, effective, and comfortable. In this blog, we’ll guide you through everything you need to know about washing and maintaining your protectors. 

The Importance of Pillow Protector

Before we move on to the care of the pillow protector, let's talk about why protectors are important. These protectors create a barrier between your pillow and everyday contaminants—body oils, sweat, hair pomades, drool, and allergens like dust mites or pet dander and pollen. Over time, all of those contaminants can compromise the filling of the pillow which leads to deterioration and also causes yellowing, unpleasant odors, or mold growth.

Additionally, if you have allergies or asthma, a hypoallergenic protector can be very effective because it keeps dust mites and other microscopic allergens that would normally trigger your allergies out of your pillow.

How Often Should I Wash My Pillow Case?

In general, protectors should be washed every 3 to 4 weeks. However, if you sweat heavily at night, have allergies, or have pets that sleep in your bed, you should wash them every 1 to 2 weeks. Making sure to wash your pillow covers in a timely way, will eliminate dirt and allergens, and help maintain a clean sleeping environment.

Washing Guidelines Depending on Fabric

Pillow cover are not created equally and here is a breakdown of how to wash them based on their fabric material:

Cotton Pillow Protectors

• Use a mild detergent that will not compromise the materials. 

• Don’t use bleach and fabric softeners. 

Waterproof Pillow Protectors

• Most waterproof fabric pillows, can have a layer of TPU (thermoplastic polyurethane á barriers to liquids) 

• Only wash in cold water to maintain the waterproof area.

• Gentle cycles are needed and avoid bleaching with harsh detergents. 

Hypoallergenic or Allergen Blocking Pillow Protectors

• Similar to cotton and microfiber but may reenforce or add other weaves or coatings. 

• Check the care label for specific instructions. 

• Avoid washing in high temperatures that may damage protective coatings.

Advice for Efficient Pillow Cleaning

• Zip it: Make sure to always zip your Pillow cover before washing it. This way, the zipper will not get caught on other fabrics, and the shape of the protector can be maintained.

• Don't Stuff the Machine: Ensure your pillow cases has plenty of room to adequately tumble during the washing cycle.

• Double Rinse: If you have sensitive skin or allergies, add a rinse cycle (starting a 'new' wash with basically only water in) to make sure as much detergent has been eliminated following your wash.

• Select appropriate Detergent: Look for anti-allergen detergent. This kind of detergent is considered to be unscented and intended to be used on sensitive skin.

Drying and After Washing Care

• Select the low-heat or air-dry setting and be careful not to damage your pillow protector by drying it at too high of heat (loss of shape & shrinkage)

• If air drying, hang your protector in a ventilated space and make sure to let your pillow protector fully dry out before putting it back on your pillow and bed.

• Never iron waterproof or TPU-backed pillow protectors - the heat will melt the barrier.

Mistakes to Avoid

• Bleach: Even if it seems like a good choice for disinfection, bleach breaks down many fabrics and waterproof layers.

• Not enough washing: This will cause build-up and tear down protection over time.

• Ignoring the manufacturer's care label: Following the manufacturer's guidelines provides the best chance of having your product perform as intended.

When to Replace a Pillow Protector ?

• Noticeable yellowing or irreparable stains

• Tears or missing zippers

• Missing waterproofing or hypoallergenic effectiveness
