Your Guide to Washing Sofa Covers Without Shrinking

Posted on 18/09/2025

Washing sofa covers can be daunting, especially if you're worried about shrinkage. Many homeowners invest in comfortable and beautiful sofas only to find their covers looking ill-fitted or damaged after a wash. If you're searching for methods on how to wash couch covers effectively while maintaining their original fit and look, you've come to the right place. This in-depth guide offers expert advice, step-by-step instructions, and essential maintenance tips so you can keep your couch slipcovers fresh, clean, and perfectly sized.

Why Do Sofa Covers Shrink in the Wash?

Shrinkage is a common concern for anyone washing furniture covers. This happens when the fabric fibers contract due to several reasons:

Water temperature: Hot water causes fibers to constrict, leading to shrinkage.
Agitation: Excessive agitation in the washing machine can distress and alter the shape of the fabric.
Drying process: High heat from the dryer or direct sunlight can further constrict fibers, making the fabric smaller.
Material type: Natural fibers like cotton and linen are more prone to shrinking than synthetics like polyester or microfiber.

Knowing what causes shrinkage puts you in control and helps you adopt suitable washing and drying methods for your removable couch covers.

How to Check if Your Sofa Covers Are Machine Washable?

Before attempting to clean your removable sofa covers, check the attached care label. Most reputable sofa manufacturers include cleaning instructions. These labels show you:

Recommended washing temperature
Whether machine washing is safe
If hand washing is preferable
Drying and ironing instructions

If your slipcovers do not have a label, consult the manufacturer's website or customer support for proper guidelines.

Typical Fabric Types and Cleaning Methods

Cotton: Machine washable; use cold water to prevent shrinkage.
Linen: Hand wash or gentle cycle; air dry only.
Polyester: Machine washable; less prone to shrinking.
Velvet: Usually dry clean only; some can be steam cleaned.
Microfiber: Safest on gentle cycle; air dry or tumble dry low.

Preparation: The Key to Washing Sofa Covers Without Shrinking

Gather Your Cleaning Supplies

Mild liquid laundry detergent
A soft microfiber cloth
A soft-bristled brush (optional for stains)
Stain remover (optional)
Clean, dry towels

Pre-Wash Checks

Remove the slipcovers carefully, avoiding force that may tear zippers or seams.
Close all zippers and fastenings to prevent snagging.
Shake out dust and debris before washing.
Spot treat stains with a gentle remover before washing the whole cover.

Step-by-Step Guide: How to Wash Sofa Covers & Prevent Shrinking

1. Spot Cleaning First

For minor spills or stains, spot clean with a mild solution of water and detergent using a soft cloth. Pat the spot gently and avoid excessive rubbing, which may stretch or fuzz the fabric.

2. Choose the Right Washing Machine Settings

Cold water: Always use cold water, unless care instructions specify otherwise. Hot water is the leading cause of shrinkage.
Gentle/delicate cycle: The less agitation, the better. The gentle cycle reduces strain on the fabric fibers.
Low spin speed: A reduced spin prevents friction and fabric damage.

Pro tip: Wash slipcovers alone or with items of similar color to avoid dye transfer and abrasion.

3. Pick a Suitable Detergent

Use a mild, liquid detergent. Avoid harsh chemicals, bleach, or fabric softeners as they can harm and weaken fabric fibers, increasing the risk of shrinkage.

4. Rinse Thoroughly

Always allow an extra rinse cycle to ensure all detergent residue is removed, as leftover soap can stiffen or discolor fabric.

5. Skip the Dryer

Air dry flat: The safest method to prevent shrinkage is to air dry your covers. Lay them flat on a clean surface (like a towel or drying rack) away from direct sunlight to avoid fading.
Hang dry: Hanging works if you support the fabric evenly to prevent it stretching out of shape.

Never use high heat or tumble dry unless the care label expressly permits it.

6. Iron Only If Needed

If the covers are wrinkled, gently iron them on a low heat setting while still slightly damp. Use a pressing cloth to avoid making the fabric shiny or burnt.

7. Refit While Slightly Damp

For the best fit, place sofa covers back on the cushions while they are still just a little damp. This helps the covers conform perfectly to the sofa's shape as they finish drying, ensuring a tailored look and minimizing any residual shrinkage.

Extra Tips for Washing Sofa Slipcovers Without Shrinking

Wash covers together if they're meant to be a matched set, so any minimal shrinking happens uniformly and doesn't result in mismatched sizes.
Limit frequency: Over-washing wears out fabric and increases the risk of shrinkage. Spot clean between washes instead.
Quick response to spills saves your slipcovers; cleaning up messes immediately reduces deep stains and means you'll wash the full cover less often.
Rotate usage: If you have a spare set of covers, alternate washing and use to keep your sofa looking its best while prolonging the life of each cover.

How to Hand Wash Sofa Covers to Avoid Shrinking

For delicate or vintage materials, hand washing sofa covers is the safest bet. Follow these steps:

Fill a clean bathtub or large basin with cold water.
Add a small amount of mild detergent, mixing thoroughly to avoid spots.
Submerge the sofa cover completely, gently agitating by hand for a few minutes to loosen dirt.
Do not wring or twist the covers. Press down gently to remove soapy water, then rinse under cold running water until clear.
Press between clean, dry towels to remove excess water.
Lay flat to air dry, reshaping gently as needed.

This method protects the fibers from course agitation, drastically reducing the risk of shrinking your removable couch covers.

Common Mistakes to Avoid When Washing Sofa Covers

Skipping the care label instructions
Using hot water or high dryer heat
Overloading the washing machine, which can lead to poor cleaning and increased abrasion
Leaving stains untreated before machine washing
Washing incompatible materials together (e.g., mixing cotton with synthetic covers)
Not securing zippers, buttons, or Velcro

Dealing with Dried, Shrunken Sofa Covers: Can You Restore Them?

Shrunken sofa covers can be frustrating, but sometimes, all hope isn't lost. Here's how to attempt stretching them back:

Soak the covers in a lukewarm solution of water and gentle conditioner for 10-15 minutes.
Gently stretch the fabric by hand while it's still damp.
Lay flat and pin down the edges in the stretched position until fully dry.
Place on the sofa when partially dry to reshape further.

This method sometimes helps with minor shrinkage, especially on cotton blends. For severely shrunken covers, however, you may need professional alteration or consider purchasing replacements.

Maintaining Sofa Covers for Long-Term Freshness and Fit

Vacuum sofa covers weekly with a soft brush attachment to remove crumbs, pet hair, and dust.
Stick to a gentle cleaning routine as much as possible.
Spot clean immediately to avoid frequent full washes.
Keep pets off the furniture or use pet-friendly throws to protect slipcovers.
Store extra sets of covers in a cool, dry place when not in use.
