How to clean vertical blinds: A quick guide for window blinds cleaning

When it comes to window treatments, vertical blinds are popular in many homes. Apart from being functional, they come in different styles that match large windows and even patio doors. Regular maintenance is important to ensure they last for a long time, especially if the blinds are placed in high-traffic areas of the home. Most people, however, are unsure of how to clean vertical blinds. 

Follow the steps on cleaning vertical blinds in this guide to make sure they remain functional, beautiful, and long-lasting. 

How often should you clean vertical blinds?

Usually, an annual thorough clean is enough. However, cleaning vertical blinds should be done more regularly if the usage and location of your blinds are a little more high-traffic. The easiest way to determine this is quite simply with their appearance. If your vertical blinds start to look a little dirty, or it's coming to a year since you've cleaned them, it's time to initiate the following steps.

The more often you clean your vertical blinds, the less time it will take to complete the task. Once you understand the best way to clean vertical blinds and know which cleaning materials are best for your specific blind type, you'll be able to complete the task faster each time.

How to clean vertical blinds without removing them

While you can remove your vertical blinds to clean them if you prefer, it is not necessary and will likely save you a significant amount of time if you don't. If you want to remove them, make sure you have enough space and take a fair bit of care to avoid damaging the blinds. It is important to note that removing them for a clean may not produce the best results.

If you want to know how to clean vertical blinds fast, follow these steps:

1. Go with the ‘as needed' approach and vacuum the blinds with an upholstery wand attachment.

2. Give them a quick dust using a microfiber cloth or a thick duster.

3. If the blinds are still dirty, you'll want to spot clean the areas of concern.

When it comes to dusting and washing, the method will depend on the type of blind you have: vinyl, PVC, plastic, or fabric.

How to vacuum vertical blinds

When vacuuming your vertical blinds, you'll need your regular household vacuum cleaner with a brush or a blind-cleaning attachment. Vacuum slowly with blinds closed (side to side) to avoid bunching the slats on one end.

Here are a few reminders:

1. Ensure the blinds are full to one side.

2. Vacuum the slats individually from top to bottom.

3. Move wide slats from side to side if needed.

4. Turn the blinds to the other side and repeat.

Ensure you always vacuum from top to bottom, so you do not accidentally lift the slat off the hooks. Follow the length of the vanes instead of going across the blind.

If possible, avoid using a vacuum cleaner that is too powerful, as it will grab the blinds and increase the risk of damage. The same thing can happen if you use a vacuum cleaner that doesn't have an attachment.

How to dust vertical blinds

No matter what material your vertical blinds are made of, sometimes vacuuming isn't enough. This does not mean you need to wash the blinds! After you vacuum, feather dusting is a great way to get rid of that remaining dust. You can also use a white glove or paintbrush to achieve the same result.

If you do opt for the popular method of a feather duster, follow these steps:

1. Completely close the blinds (side to side).

2. Open and close blinds (rotation of vanes).

3. Use up and down strokes to dust one vane at a time.

4. Reverse the blinds and repeat.

For white glove cleaning of vinyl, PVC, or plastic blinds, here are the steps:

1. Close the blinds (side to side).

2. Open the blinds fully (rotation of vanes).

3. Put on white cloth gloves and carefully glide your hands over the vanes.

4. Be sure to brush the dust off the gloves or wash them between uses.

If you decide to use a paintbrush for your cleaning, follow these steps:

1. Close the blinds entirely (side to side).

2. Open and close (rotation of vanes).

3. Give the blinds a wipe with a paintbrush, preferably one that has natural fibers as opposed to plastic (a high-quality paintbrush is preferable). Tap the brush periodically.

4. Reverse the blinds and repeat.

Pro tip: Use a high-quality feather duster that pulls dust instead of rags or cloths, which will not clean as effectively.

How to wash vertical blinds

For vinyl, PVC, plastic, and painted wood blinds that require washing, you will need:

• High-quality sponges

• A mild cleanser

• Some clean towels

• A bucket of water

• A microfiber cloth (optional)

Once you have these materials, follow these steps:

1. Close all windows and doors to prevent wind and dust while cleaning.

2. Place the clean towels under the vanes to collect any drips.

3. Wet the sponges in a mild solution of soap and warm water (avoid hot water).

4. Wash one side of the blind at a time if you only use one sponge; use two sponges to wash both sides simultaneously.

5. Squeeze the excess water from the sponge.

6. Squeeze the sponge gently and slide down the blind slowly.

You can wipe a single vane in sections, intermittently cleaning the sponge to avoid a build-up of dust. To avoid leaving water spots, use an almost dry sponge to do a light drying pass at the end. You can also dry the blinds with a microfiber cloth. Ensure you refresh your bucket of water to avoid washing with a dirty sponge.

During this process, it is a good idea to use minimum pressure on the vanes to avoid pulling them out of their clip or damaging the blinds. Always make sure you are using quality sponges to avoid leaving sponge particles on the blinds, making them dirtier than before you started! Always avoid using abrasive soaps. While the vanes are dry, you can wipe them with a dryer sheet to reduce static build-up.

Pro tip: Lemon oil or wood preservative is a great way to protect wood blinds with a stained finish.

How to clean vertical fabric blinds

If your vertical blind and inserts are made of fabric, you will need some slight tweaks on how you perform a clean to ensure they last and look amazing for as long as possible.

When spot cleaning fabric vertical blinds, blot the area in question with a mild cleansing solution. It would be best to test the solution first to ensure it doesn't cause any damage. From here, use a soft cloth or sponge and softly blot the stain, allowing it to dry. Exercise a fair amount of care to avoid damaging the material.

If you need to perform a more in-depth clean other than dusting or spot cleaning, refer to the blind manufacturer’s cleaning instructions, as they will vary quite significantly across the many product lines. Many people make the mistake of washing their blinds via immersion, heat, or chemicals, which can cause damage to the material.

Keep in mind, however, that these more aggressive methods should only be used if the general instructions of the manufacturer allow it. Most manufacturers strongly advise against putting fabric blinds into a washing machine and dryer.
