Composite sinks are one of the most popular choices in modern kitchens. They combine durability, contemporary design, and excellent resistance to everyday wear. But like any kitchen investment, they need the right care to stay looking their best. With the right routine and essentials—like our Care Kit, which includes an Everyday Cleaner, a Tough Stain Remover, and Rejuvenating Mineral Oil—you can effortlessly maintain your sink’s pristine finish.
If you’ve ever wondered how to clean a composite sink without damaging the surface — or how to keep it free from stains, scratches, and water marks — this guide covers everything you need to know.
What Is a Composite Sink?
A composite sink is made from resins reinforced with glass fibres. This creates a non-porous, high-strength material that is:
- Durable – tough enough for everyday use.
- Stain and scratch resistant – designed to withstand busy kitchens.
- Heat tolerant – resilient to hot water and cookware up to ~170 °C.
- Stylish – available in matte finishes that complement modern kitchens.
Composite sinks are built to last, but to maintain their look and performance, regular cleaning and care are essential.
Everyday Composite Sink Cleaning
Daily cleaning prevents stains and keeps your sink hygienic. The best way to clean a composite sink is simple:
- Rinse away food residue.
- Use warm water and mild dish detergent with a microfibre cloth or soft sponge.
- Rinse thoroughly and dry with a soft cloth to prevent limescale spots.
Tip: For best results, use Styl Everyday Cleaner, a spray-and-wipe solution designed specifically for composite sinks.
Weekly Composite Sink Care
In addition to daily cleaning, weekly maintenance keeps your sink looking new:
- After cleaning and drying, apply Rejuvenating Mineral Oil — it’s like moisturiser for your sink, conditioning the surface and adding a protective barrier.
- Buff gently in circular motions to restore the finish.
- This step helps your sink resist stains, prevents dullness, and extends its life.
Regular oiling is one of the most effective ways to care for a composite sink.
How to Remove Stains from a Composite Sink
Composite sinks resist stains, but foods like coffee, turmeric, and red wine can sometimes leave marks. Here’s how to tackle them:
- Styl Tough Stain Remover – Apply to the affected area, leave for 5–10 minutes (but do not let it dry), scrub gently with a non-abrasive pad, then rinse.
- Natural method – Mix lemon juice with bicarbonate of soda (bicarb). Apply the paste, let sit briefly, then wipe and rinse clean.
This ensures even stubborn stains can be removed without damaging the surface.
How to Remove Limescale from a Composite Sink
Hard water can leave chalky deposits and water marks. To remove limescale from a composite sink:
- Use a commercial descaler (following the product’s instructions).
- Or spray a 50/50 vinegar and water solution, leave for 1–2 minutes, rub with a microfibre cloth, rinse, and dry.
Drying the sink after each use is the best way to prevent limescale buildup.
Fixing Scratches and Minor Marks
Light scratches or scuff marks may appear over time, but they’re easy to fix:
- Use a magic eraser sponge (non-abrasive) to gently buff the mark.
- Restore the surface by applying mineral oil or a composite sink polish.
This helps maintain the smooth matte finish that composite sinks are known for.
Composite Sink Care: What Not to Do
To protect your investment, avoid these common mistakes:
- Don’t use bleach, chlorine, or harsh chemical cleaners.
- Don’t scrub with steel wool, abrasive powders, or wire brushes.
- Don’t leave food debris, coffee grounds, or water sitting in the sink.
- Don’t place hot pans directly on the surface — always use a trivet or roll mat.
Following these simple “don’ts” ensures your composite sink lasts longer and looks better.
