Venetian blinds serve the same purpose as curtains in general. Their main function is to regulate airflow, block out sunlight, and reduce heat intensity in a room. 

Besides functioning as a thermal effect and light protector, Venetian blinds also add aesthetic value to a space.

They are multifunctional blinds that require specific cleaning techniques, featuring horizontal slats made from various materials. Due to the slatted design, they tend to obscure dirt well and are tougher to clean.

How often should I clean them?

To prevent dust, allergens, and germs from accumulating on Venetian blinds, be sure to clean them regularly, at least two times a month. But keep in mind that your environment also plays a role, and if you reside in a dusty area, you may have to clean it more frequently.

There are specific methods to clean Venetian blinds, through light or deep cleaning. 

Depending on the placement in the house, sometimes Venetian blinds tend to get dirty faster. For example, compared to Venetian blinds in the bedroom, the tendency to get dirty is higher in the kitchen.

Interestingly, since the beginning of their history, the primary material for Venetian blinds has been wood. However, there have been other types of materials used over time, including metal and pvc. The cleaning method depends on the kind of material of the blinds. Frequent cleaning will help maintain them and retain their quality.

6 Best Ways to Clean Venetian Blinds

Cleaning with a duster

  • Using a duster is more appropriate for light cleaning, and it involves a quick clean with a dry duster when the Venetian blinds are not too dusty or dirty.
  • You can do this every other week to prevent dust from accumulating and is suitable for all types of Venetian blinds.  

Cleaning with a damp cloth

  • This cleaning method is most suitable for real wooden Venetian blinds. Since they do not tolerate any moisture, they can swell or warp if you use anything more than a damp cloth.
  • Apply this method if the blinds require more than just light cleaning. Wet the cloth, then squeeze the water until it becomes damp. Use it to remove all dirt or stains on the slats. 
  • Be sure not to leave any water on the blind’s surface and use a dry cloth or paper towel to dry it off, making sure you wipe it thoroughly.

Cleaning with spray

  • You can use a dusting spray if you like to save time when cleaning your Venetian blinds. Spray a clean microfibre cloth with it, and wipe as normal. Avoid oversaturating the cleaning cloth as this may cause the wood to distort.
  • Wipe across the slats, cleaning each one individually to remove excess dust. Avoid spraying directly onto the blinds and be sure to clean all parts of the blinds, including handles and strings. 
  • Systematically clean each slat, beginning in the middle and working outwards. After cleaning all the slats on one side, switch to the other side and repeat the process. This cleaning method is most suitable for PVC, metal, and faux wooden materials. For authentic wooden materials, opt for a mild spray cleaner. 

Using a vacuum cleaner

  • Using a vacuum cleaner is another method that is quicker and more effective. The suction is powerful enough to slightly pull the slats without scratching and chipping them. However, only use this method if you have an upholstery brush, and never use the vacuum hose without it.
  • As you slide the vacuum along the slats, hold on to them. You can do this by just gripping the slat’s end, moving to the opposite side as you keep a firm grip on it. Reduce the vacuum’s suction power to the lowest setting to prevent the risk of damaging the slats. For a more efficient way of cleaning, close the slats. 
  • After completing the front part of the blind, continue the process to cover the back of the slats. Cleaning with this method is suitable for all types of Venetian blinds.

Scrubbing to get rid of dirt and germs

  • You can use vinegar instead of detergent to remove dirt and germs from your Venetian blinds. Besides being non-toxic and eco-friendly, you can use vinegar to clean blinds of various materials, including wood, faux wood, metals, and plastic. 
  • You can use a sponge, microfibre cloth, or other fabric types for this method. Combine equal parts of water and vinegar in a bucket or a bowl. If you were to choose a microfibre cloth to clean – dip it into the mixture, squeeze to remove excess water and wipe each slat, end to end, one at a time. Be sure to cover all areas. Rinse the cloth with clean water after wiping each slat. Repeat the same step until finished.
  • If there is stubborn or sticky dirt you can simply use more vinegar. Use warm water to mix with the vinegar
  • Avoid vigorous rubbing to prevent the risk of scratching the slats. It is better to use a dual-sided sponge to use the rough side to scrub the dirt gently. 
  • Similarly to other methods, for a more efficient way of cleaning Venetian blinds, close the slats.

Soak it in the bath

  • You will need to remove the blinds entirely from their fittings for this cleaning method.
  • Lay the blind flat on the bath’s surface. You may use a cloth or towel as a base if you are worried about the risk of scratching the blind. Pour warm water until the slats are immersed but avoid soaking the metal parts to prevent rusting. Add mild detergent or vinegar as an eco-friendly alternative. Use a soft brush to clean the slats. 
  • Finally, after brushing the blind thoroughly, rinse it with cold water until all the soap has been washed away. Hang it to dry before reinstalling it on the window. If you need to install it immediately, use a hair dryer or paper towel to expedite the drying process. To prevent mould from developing, ensure the blinds are completely dry before reinstalling them. 
  • To remove more stubborn stains, soak the blinds for a few hours before cleaning. You can also soak the blinds overnight in the bath for especially stubborn stains. However, if you do not have a bath, you can clean it anywhere using a flat surface. Only a bit of effort is needed to brush off stubborn stains without soaking them first. Always brush the blinds gently to avoid scratching them.
  • Please keep in mind, this cleaning method is suitable for all materials except authentic wood. Natural wood cannot tolerate excessive water and humidity; therefore, using this method can damage the blinds. The reason is, when wood becomes damp, it warps. Wood has teeny-tiny pores that absorb water and cause it to expand. The pores in the wood compress as it dries, resulting in the blind becoming twisted or distorted. 


Venetian blinds are one of the most popular window blinds. They can transform your home’s appearance and work exceptionally well as heat and light protectors.

Maintenance of this type of blind plays an essential role in keeping them in excellent working condition. You can use cleaning tools and accessories readily found in most homes. The most important thing to remember is to use suitable cleaning methods for the different materials of the Venetian blinds.

When cared for appropriately, they can last for years to come and be a beautiful addition to any home.
