5 Stains That Will Ruin Your Curtain (And How To Remove Them)

Wondering what kind of stains can permanently damage your curtains?

In Singapore homes, the most common culprits are food and drink spills, mould from humidity, ink marks, pet accidents, and smoke odours. Left untreated, these stains don’t just look unsightly — they can weaken fabric and shorten the lifespan of your curtains.

The good news? Each stain can be managed with the right cleaning method. Here’s a guide to identify and remove the 5 stains that will ruin your curtains before it’s too late.

1. Food & Drink Stains

Spilled coffee, tea, curry, or juice can leave dark marks that are difficult to remove if they set.

How to remove:

• Blot excess liquid immediately with a clean cloth.
• Mix mild detergent with warm water and dab gently.

For greasy stains, sprinkle baking soda first to absorb oil before wiping.

2. Mould & Mildew

Singapore’s humid climate makes mould and mildew a frequent problem, especially on curtains near windows.

How to remove:

• Brush off loose spores outdoors.
• Apply a vinegar and water solution, then rinse with mild detergent.

Fully sun-dry curtains to prevent regrowth.

3. Ink Stains

A stray pen or marker can leave stubborn blue or black marks on fabric.

How to remove:

• Dab the stain with rubbing alcohol using a cotton ball (always test a small patch first).
• Avoid scrubbing, which can spread the ink.

For delicate fabrics or large stains, professional cleaning is recommended.

4. Pet Stains

Pets can leave paw prints, drool, or urine stains that not only discolour curtains but also leave lingering odours.

How to remove:

• Blot liquids immediately.
• Use an enzyme-based cleaner to neutralise stains and smells.

Wash with fabric-safe detergent and air dry thoroughly.

5. Smoke & Odour Stains

Cigarette smoke or cooking fumes can cling to curtains, causing yellowish stains and unpleasant odours over time.

How to remove:

• Wash curtains in warm water with vinegar added to the cycle.

• Steam clean delicate fabrics to refresh them without damage.

Regularly air curtains under sunlight to prevent long-term odour build-up.
