Would you like to ensure that your exterior venetian blinds operate reliably for many years?
Exterior Venetian Blind Cleaning – Key Points at a Glance

• Exterior venetian blinds should be cleaned regularly – ideally in spring and autumn.

• Coarse dirt can be removed using water, mild soap, and a soft brush.

• Professional cleaning is recommended for heavy soiling or hard-to-reach areas.

• Cleaning the blinds from the inside is possible if the window can be tilted or if special cleaning tools are used.

• Always ensure proper safety when working at height.

Why Is Cleaning Exterior Venetian Blinds Important?

Exterior venetian blinds are constantly exposed to weather conditions. Dust, pollen, insects, bird droppings, and other contaminants gradually accumulate on the slats. Without regular cleaning, blinds can become unsightly and their functionality, as well as precise light control, may be compromised.

Thorough cleaning significantly extends the service life of exterior venetian blinds. This is especially important for high-quality shading solutions such as ROLTEK HERO exterior venetian blinds, known for their durability and superior quality.

How to Clean Exterior Venetian Blinds – Step-by-Step Instructions

To keep your shading system functional and visually appealing over the long term, regular and thorough cleaning is recommended.

1. Preparation

• Switch off the control system (electric or manual).

• Adjust the slats to a horizontal position.

• Check accessibility – a telescopic pole may help with difficult-to-reach areas.

2. Removing Coarse Dirt

• Use a soft broom or hand brush to remove loose dirt from top to bottom.

• Do not use sharp tools to avoid damaging the surface.

3. Cleaning with Water and Mild Detergent

• Prepare lukewarm water with a mild cleaning agent.

• Use a soft brush or microfiber cloth.

• Clean each slat individually – front and back.

• Clean ladder tapes in the raised position.

• Rinse everything thoroughly with clean water.

4. Drying the Blinds

• Dry the slats with a soft cloth or allow them to air dry.

• Once dry, fully raise and lower the blinds to remove any remaining water.

Tips for Cleaning Exterior Venetian Blinds

• Clean at least twice a year.

• Use gentle cleaning agents without aggressive chemicals or pressure washers.

• Ensure proper protection when working at height.

• Clean early in the morning or in the evening, when surfaces are not exposed to direct sunlight.

Cleaning Exterior Venetian Blinds from the Inside – Is It Possible?

In principle, yes – but only under certain conditions. The window must open wide enough or be tilt-openable to allow access to the slats.

Telescopic poles with special brush attachments are particularly useful for reaching difficult areas. If this is not possible or if the blinds are installed at a great height, it is safer to entrust the cleaning to professionals.

Professional Cleaning – When Is It Worth It?

Professional cleaning is recommended in the following cases:

• heavily soiled or severely weathered blinds,

• cleaning at great heights or in hard-to-access locations,

• lack of appropriate equipment or experience.

Costs vary depending on surface size, degree of soiling, and accessibility. Consulting a professional service provider allows for a more accurate assessment.
