Deciding whether to undo zips before washing your clothes is a common laundry question. Generally, it’s a good idea to unzip zippers on garments before they go into the washing machine to prevent damage to both the zipper and other items in the load.

Why Unzipping Zippers Before Washing Matters

Washing machines can be tough environments for your clothes. The tumbling action, combined with water and detergent, can put a lot of stress on fabrics and hardware. Leaving zippers zipped can lead to a few problems.

Preventing Damage to Zippers and Garments

When a zipper is left closed, its teeth can snag on other clothing items. This snagging can cause pulls, tears, or holes in delicate fabrics. It can also put undue stress on the zipper itself, potentially bending or breaking the teeth.

Furthermore, the metal or plastic of the zipper can scratch or damage other garments in the wash. This is especially true for items with sensitive finishes or embellishments. Undoing the zipper removes this risk.

Protecting Your Washing Machine

The sharp edges of an open or partially open zipper can also pose a threat to your washing machine. They can scratch the drum of the machine, leading to cosmetic damage. In more severe cases, a broken zipper tab or teeth could even get caught in moving parts, potentially causing malfunctions.

Ensuring a Thorough Clean

While less common, a zipped-up pocket or fly can sometimes prevent water and detergent from reaching the fabric inside. Unzipping these areas ensures that all parts of the garment get properly cleaned. This is particularly important for items like jeans or jackets where pockets might hold debris.

When It Might Be Okay to Leave Zippers Zipped

While the general advice is to unzip, there are a few situations where it might not be strictly necessary. However, it’s still often the safer choice.

Very Delicate Wash Cycles

If you are using an extremely gentle or hand-wash cycle on a machine that offers very minimal agitation, the risk might be lower. However, even in these cycles, snagging can still occur.

Items Made Entirely of Sturdy Material

Garments made from very thick, durable materials like heavy denim might withstand the washing process with zippers intact. Still, the risk to other, more delicate items in the same load remains.

Best Practices for Washing Zipped Items

To ensure your clothes and your washing machine stay in good condition, follow these simple steps:

• Unzip all zippers: This is the most crucial step. Make sure they are fully unzipped.
• Fasten Velcro: Just like zippers, Velcro can snag on other fabrics.
• Turn items inside out: This protects the outer surface of the garment and the zipper teeth.
• Use a mesh laundry bag: For delicate items or those with prominent zippers, a mesh bag adds an extra layer of protection.

Can Zippers Rust in the Wash?

Metal zippers can potentially rust if exposed to prolonged moisture and certain detergents. Unzipping them and ensuring they are dry after washing can help prevent this. However, modern zippers are often made with rust-resistant materials.

Should You Zip Up Jackets Before Washing?

It’s generally recommended to unzip jackets before washing. While zipping them might seem like it keeps them together, the zipper teeth can still cause damage to other items or even the jacket itself during the wash cycle.

What About Zippers on Jeans?

Yes, you should unzip the fly on your jeans before washing them. This prevents the zipper teeth from snagging on other clothes and also ensures the area around the fly gets thoroughly cleaned.

Summary: Zip It or Unzip It?

The consensus among laundry experts and garment care guides is that unzipping zippers before washing is the best practice. It actively prevents damage to your clothes, protects your washing machine, and ensures a cleaner wash. While there might be rare exceptions, the small effort of unzipping saves potential headaches and repair costs down the line.
