Cleaning plastic blinds can seem like a daunting task, especially when dust and grime accumulate over time. However, using a bathtub to clean them is an effective and convenient method that saves time and effort. This guide will walk you through the steps of how to clean plastic blinds in bathtub.

Importance of Regularly Cleaning Plastic Blinds
Regularly cleaning plastic blinds is essential for maintaining a fresh and hygienic living space. Over time, blinds collect dust, pollen, and other allergens that can negatively impact indoor air quality and contribute to respiratory issues.
Additionally, grease and grime buildup can cause discoloration, making the blinds appear worn-out and unappealing. Regular cleaning not only enhances the aesthetic of your home but also extends the lifespan of the blinds, ensuring they remain functional and attractive for years to come. By incorporating blind cleaning into your routine maintenance, you can create a healthier and more pleasant environment for you and your family.
Signs Your Blinds Need a Deep Clean
Over time, blinds can accumulate dust, dirt, and grease, which may not always be noticeable at first glance. However, there are some clear signs that indicate your blinds require a deep clean. First, if you notice visible dust or grime buildup that doesn’t come off with a light dusting, it’s time for a more thorough cleaning. Second, unpleasant odors emanating from the blinds could signal a significant accumulation of dirt, moisture, or even mold. Third, discoloration or staining, especially on lighter-colored blinds, often highlights the need for a deep clean.
Lastly, if operating your blinds becomes difficult due to dirt buildup in the mechanisms, a deep clean can help restore their functionality. Identifying these signs early ensures your blinds remain hygienic, aesthetically pleasing, and fully operational.
Necessary Cleaning Supplies
To properly clean your blinds and ensure they are both hygienic and visually appealing, you’ll need the right supplies. Here’s a list of essential items to have on hand:
- Soft Microfiber Cloths – Ideal for dusting and wiping down surfaces without causing scratches.
- Vacuum Cleaner with Brush Attachment – Helps remove accumulated dust and debris efficiently.
- Gentle Cleaning Solution – A mild soap or vinegar-based solution works well for removing grime without damaging materials.
- Bucket of Warm Water – Suitable for rinsing or diluting cleaning products as needed.
- Soft Sponges or Brushes – Useful for tackling stubborn spots or dirt.
- Lint-Free Towels – Perfect for drying the blinds thoroughly to avoid water stains.
- Disposable Gloves – Protect your hands when handling cleaning solutions or dirty surfaces.
Having these supplies ready ensures you can clean your blinds effectively without causing any damage to their material or mechanisms.
10 Methods How to Clean Plastic Blinds in Bathtub
1. Remove the Blinds Carefully from the Window
The first and most important step is to safely remove the plastic blinds from the window. Gently unhook or detach the blinds from the mounting brackets, ensuring that you don’t damage the headrail or cords in the process. If your blinds have a tilt wand or pull cords, gather and secure them using a rubber band to prevent tangling.

Lay the blinds flat on the floor to inspect them before placing them in the tub. Proper removal prevents unnecessary strain on the structure and makes the cleaning process much easier.
2. Prepare the Bathtub with Warm Water and Mild Detergent
Fill your bathtub with enough warm water to fully submerge the blinds. Add a few tablespoons of a gentle dishwashing liquid or a mild all-purpose cleaner to the water. Avoid harsh chemicals like ammonia or bleach unless the blinds are heavily soiled and made from bleach-safe plastic. Stir the water slightly to create suds and evenly distribute the soap. This solution will begin loosening surface grime and dust, making the soaking phase much more effective. A clean and appropriately filled tub sets the foundation for a successful deep clean.
3. Soak the Blinds for 30 Minutes to Loosen Dirt and Grime
Once the blinds are fully submerged in the soapy solution, allow them to soak for about 30 minutes. This soaking period is crucial, as it softens and lifts dirt, grease, and buildup from the slats and cords. If your blinds are especially grimy—like those near a kitchen stove—you can let them soak for up to an hour. Be sure to occasionally swish the blinds around in the water to help dislodge particles. This passive step saves time during the actual scrubbing and reduces the need for aggressive cleaning.

4. Scrub the Slats Gently with a Soft Sponge or Brush
After soaking, use a soft sponge, microfiber cloth, or a soft-bristle brush to gently scrub each slat. Start from one end and work your way across, flipping the blinds halfway through to clean both sides. For horizontal blinds, it’s easiest to clean one section at a time while keeping the rest submerged. Pay close attention to the edges and ends where grime tends to accumulate. Use gentle pressure to avoid bending the plastic slats. A toothbrush is handy for cleaning around cord holes, joints, and other tight areas.
5. Rinse Thoroughly with Clean Water to Remove Residue
Once all slats have been scrubbed, drain the soapy water from the tub and rinse the blinds thoroughly. You can use a handheld showerhead, a large plastic pitcher, or simply refill the tub with clean water. Make sure all soap, loosened dirt, and suds are completely rinsed away. Any leftover residue can leave streaks or attract dust more quickly after the blinds are reinstalled. Take your time during this step to ensure every slot is clean and residue-free.
6. Use White Vinegar for Mold and Mildew Removal
If your plastic blinds have developed mold or mildew—common in humid bathrooms—a soak in white vinegar can help sanitize and refresh them. After an initial wash, refill the tub with warm water and add two cups of distilled white vinegar. Let the blinds soak for 15 to 20 minutes, then rinse again thoroughly. Vinegar naturally kills mold spores and deodorizes the blinds without harsh chemicals. This step is particularly beneficial for allergy sufferers or those seeking an eco-friendly solution.
7. Dry the Blinds with Towels or Let Them Air Dry Flat
After rinsing, lay the blinds flat on a large towel or clean sheet on the bathroom floor or across a countertop. Pat them dry with towels to remove excess water, especially from the cords and headrail. You can also stand the blinds upright in the tub to let water drip off before transferring them. Ensure the blinds are completely dry before rehanging them to prevent water spots, mold, or rust on metal parts. Air drying in a well-ventilated space accelerates the process and preserves the structure of the blinds.

8. Spot-Treat Stubborn Stains with Baking Soda Paste
If there are still stubborn stains or sticky spots after soaking and scrubbing, make a paste using baking soda and a few drops of water. Apply it directly to the stain with a cloth or sponge and scrub gently in a circular motion. Let the paste sit for a few minutes before rinsing. Baking soda’s mild abrasiveness helps remove grease and grime without scratching the plastic surface. This method is especially useful for blinds in kitchens or smoking areas where yellowing and tackiness are common.
9. Polish with Fabric Softener for Dust Repellence
A unique but effective method to repel future dust buildup is to lightly wipe the cleaned and dried slats with a diluted fabric softener solution. Mix one part fabric softener with four parts water in a spray bottle, lightly mist a microfiber cloth, and gently run it along each slat. This adds a thin, invisible coating that reduces static cling and helps repel dust, making your blinds stay cleaner for longer. This finishing touch not only makes your blinds smell fresh but also extends the time between cleanings.
10. Reinstall the Blinds and Perform Regular Maintenance
Once your plastic blinds are fully dry and sparkling clean, carefully reattach them to the window brackets. Test the tilt and lift mechanisms to ensure everything works smoothly. To keep them looking fresh between deep cleans, dust them weekly using a microfiber duster, vacuum brush attachment, or a specialized blind cleaner. A light monthly wipe-down with a damp cloth will help prevent the buildup of grime, meaning fewer bathtub soaks over time. Routine upkeep is key to maintaining the cleanliness and appearance of your blinds without extra effort.

Conclusion
