Vertical blinds are fantastic for controlling light and privacy, but let’s be honest: they are absolute dust magnets. Because they hang vertically, you might think they stay cleaner than horizontal blinds, yet they still manage to collect grime, pet hair, and allergens.
The good news? You don’t always have to take them down to get them sparkling again. Whether you need a quick spot clean or a deep soak for neglected blinds, we have you covered.
Here is exactly how to clean vertical blinds without losing your mind, including methods for leaving them on the rail and washing them in the tub.
Key Takeaways
- Vacuum your blinds with a brush attachment weekly to prevent heavy dust buildup.
- Spot clean fabric blinds while they hang using warm water, dish soap, and a microfiber cloth.
- Deep clean durable blinds by submerging them in a bathtub with mild detergent; always remove bottom weights first.
- Avoid hot water and high-heat drying, as high temperatures can melt the glue holding the fabric weights.
How to Clean Vertical Blinds Without Removing Them
If the thought of unhooking dozens of individual slats makes you want to give up before you start, don’t worry. This is the best method for regular maintenance or for blinds that are just a little dusty. It works best for fabric blinds, but you can use it on vinyl too.
What You Need
Grab these supplies before you start:
- Vacuum with a brush attachment.
- Soft dusting brush or duster.
- Large bowl or bucket.
- Dish soap.
- Warm water.
- Microfiber cloths.
- Old towels (to protect the floor).
Step-by-Step Instructions
Follow these steps to refresh your blinds right where they hang.
- Protect the floor: Lay a few old towels underneath the window. Even if you are careful, dirty water might drip, and you don’t want that on your carpet or hardwood.
- Dust first: Use a duster to knock off the loose layer of surface dust. Do this from top to bottom so the dust falls toward the floor.
- Vacuum gently: Attach the soft brush tool to your vacuum. Run it down the length of each slat. Support the blind with your free hand from behind to stop it from sucking into the nozzle or crumpling. Always go top-to-bottom to avoid unhooking the slat.
- Mix your solution: Fill your bowl with warm water (not hot) and add a tablespoon of dish soap. Agitate it until it gets bubbly.
- Wipe the blinds: Dip a microfiber cloth into the suds and wring it out until it is just damp. If it is dripping, it is too wet. Wipe each slat gently in a downward motion. For stubborn spots, support the fabric with your hand and rub in small circles.
- Rinse (Optional): If you used a lot of soap, wipe them again with a fresh cloth dampened only with plain water to remove residue.
- Let them dry: Leave the windows open or turn on a fan to help air circulate. Ensure the blinds are hanging straight so they dry without wrinkles.
Top Tip
Avoid using paper towels on fabric blinds. The wet paper can disintegrate and leave lint stuck to the texture of the fabric, which is a pain to remove.
How to Clean Vertical Blinds in the Bathtub
Sometimes a quick wipe isn’t enough. If your blinds have deep stains, nicotine yellowing, or years of grime, a bathtub soak is the answer.
Note: Check your manufacturer’s label first. Some fabric blinds cannot be submerged, and wooden blinds should never be soaked.
What You Need
- Vacuum with brush attachment.
- Dish soap or mild laundry detergent.
- Clean bathtub.
- Microfiber cloths or a soft sponge.
- Large drying towels.
Step-by-Step Instructions
This process takes longer but yields the best results for dirty blinds.
- Pre-clean: Dust and vacuum the blinds while they are still hanging. It is much harder to remove wet dust later.
- Remove hardware: This is critical. Unclip the chain at the bottom and slide out the weights from the pockets of each slat. If you wash the weights, they can rust or damage the fabric.
- Unhook the blinds: Carefully unclip each slat from the headrail. Usually, you lift slightly and tilt to release the hook.
- Prepare the bath: Fill the tub with lukewarm water. Do not use hot water; anything over 86°F (30°C) can melt the glue that holds the weight pockets together. Mix in a gentle detergent.
- Soak: Place the slats in the water. Avoid folding or creasing them sharply. Let them soak for about an hour so the detergent can break down the grease and dirt.
- Gently scrub: Use a soft sponge or cloth to wipe down each slat while it is submerged. Pay extra attention to stained areas.
- Rinse well: Drain the dirty water. Refill the tub with cool, clean water to rinse, or hold each slat under the showerhead until the water runs clear. Soap residue can attract more dirt later, so be thorough.
- Dry flat: Lay towels on the floor or over a drying rack. Place the slats flat on top. Do not hang them in direct sunlight or over a radiator, as they might shrink. Once they are damp-dry (not dripping), you can hang them back on the rail to finish drying in shape.
FAQs About Cleaning Vertical Blinds
How Often Should You Clean Blinds?
You should dust or vacuum your vertical blinds once a month to prevent buildup. A deep clean (washing in the tub) is usually only necessary once a year, or when you notice visible stains or discoloration.
How Do I Remove Black Mold from Blinds?
If the mold is surface-level, you can spot clean it with a mixture of white vinegar and water. However, vertical blinds are often porous. If the mold has penetrated the fabric fibers, it is often safer and easier to replace the individual slats rather than risking your health to scrub them.
Expert Tip
Always wear a mask and gloves when dealing with mold spores to prevent inhaling them.
How Do I Get My Vertical Blinds White Again?
Soaking them in the bathtub is the best way to restore brightness. You can add a few cups of dissolved oxygen bleach (like OxiClean) to the bathwater. This is safer for the fabric than chlorine bleach. If you must use chlorine bleach, use a very weak solution and ensure the blinds are white vinyl, not fabric, as bleach can damage synthetic fibers.
Can You Put Vertical Blinds in the Washing Machine?
Technically yes, but it is risky. If the care label says it is safe, roll the slats up and place them inside a mesh laundry bag or a tied pillowcase to stop them from fraying. Wash on a delicate cycle with cold water (max 86°F). Never put them in the dryer; the heat will destroy them.
Can You Clean Vinyl Blinds with Bleach?
Yes, vinyl is generally tough enough to handle diluted bleach. However, harsh chemicals can sometimes cause vinyl to yellow over time or become brittle. A safer bet is a strong degreaser or dish soap. If you use bleach, rinse it away very thoroughly.
Is Steam Cleaning Safe for Vertical Blinds?
Steam cleaning is excellent for killing bacteria, but you have to be careful. The high heat can melt the glue in the bottom pockets or cause plastic slats to warp. If you use a steamer, keep the nozzle moving constantly and hold it a few inches away from the fabric.
How Do You Spot Clean Stains Without Water Marks?
The trick is to not over-saturate the fabric. Dab the stain with a small amount of foam from your soapy water or a dedicated stain remover. Blot, don’t rub aggressively, with a dry cloth immediately after. Drying the area quickly with a hair dryer on a cool setting can also help prevent water rings.
How Do I Clean the Bottom Chains and Weights?
Since you removed these before washing the blinds, you can soak the plastic chains and weights in a bowl of warm soapy water. Use an old toothbrush to scrub away any grime in the crevices. Rinse them off and dry them completely before reassembling your blinds.
