Curtains and Fabrics: How to Keep Them Clean and Protected Indoors and Outdoors
26 June 2025
Curtains – both indoor and outdoor – are essential elements for the comfort, aesthetics, and functionality of the spaces we live in. They provide protection from light, prying eyes, and, in the case of outdoor curtains, even from the elements. But because of their exposed role, it’s crucial to know how to clean curtains properly to prevent dirt, moisture, and wear from compromising their effectiveness and appearance.
For this reason, Marbec offers two specific products designed for those looking to understand how to clean curtains and protect fabrics, suitable for both outdoor and indoor use.

Outdoor Fabrics: More Exposure, More Care
Awnings, gazebos, umbrellas, and outdoor covers are constantly exposed to:
- Urban smog
- Mold and algae
- Dust and sand
- Salt (especially in coastal environments)
- Bird droppings
If not removed, these agents can damage fabrics, fade colors, and even compromise their durability.
Deep Cleaning with PULISCI TENDE
PULISCI TENDE is a stain-removing cleaner specifically designed for outdoor fabrics. It works deep down without damaging the fibers or altering the colors. It is ideal for materials such as:
- Acrylic
- Polyester
- Dacron
- Nylon
- Kevlar

Main benefits:
- Quickly removes mold, dirt, smog, and salt deposits
- Solvent-free, odorles
- Ready to use: simply spray, let it work, scrub, and rinse
Note: PULISCI TENDE is intended for outdoor use only.
PROTEX: The Invisible Protection for Outdoor and Indoor Fabrics
After cleaning the fabrics, it’s essential to protect them to prolong the results over time. This is where PROTEX comes in — a water-repellent and dirt-resistant protector, perfect for both outdoor and indoor use.
Where is PROTEX used?
- Awnings, gazebos, and umbrellas
- Nautical and car covers
- Indoor curtains in linen, cotton, polyester…
- Upholstery, cushions, sofas, carpets

Apply to a clean, dry surface by spraying evenly from about 30 cm away. The protective effect fully stabilizes within 24 hours.
Indoor Fabrics: Hygiene and Beauty to Preserve
Even though they are less exposed to weather conditions, indoor fabrics still accumulate dust, allergens, smoke, kitchen residues, and moisture. A protective treatment like PROTEX helps to:
- Prevent stains and marks
- Make fabrics easier to clean
- Preserve color and texture over time
Pairing PROTEX with a gentle indoor cleaner like PULI TEX completes the care cycle.
Stone, a symbol of memory and endurance, changes over time and requires care. Products like TIXO and PULITORE FC gently remove smog and dirt, while ACTIV 3 restores and protects surfaces. Metals too, prone to oxidation, need specific cleaners that preserve their shine. Regular maintenance keeps the beauty and value of stones and monuments intact over time — a gesture of respect and remembrance.
Discover how to keep your outdoor surfaces looking their best with the use of specialized products like Alganet, a powerful cleaner, combined with effective tools such as the Brown Pad and TIM. These elements are essential for ensuring a deep, long-lasting clean for exterior walls, which are constantly exposed to weather and pollution. Alganet works by removing moss, algae, and embedded dirt without damaging the underlying materials. The Brown Pad allows for thorough cleaning even on delicate surfaces without scratching them, while TIM completes the treatment by protecting the walls from future buildup. Beyond cleaning, it’s important to adopt regular preventive care practices to help maintain the appearance of these structures over time. With the right approach, your walls won’t just look immaculate—they’ll also be shielded from premature wear, ensuring lasting beauty!
