What fabrics can I use Stain Remover on?Updated 15 hours ago
TL;DR: Stain Remover is suitable for cotton, denim, polyester, nylon and most everyday household laundry. Avoid wool and other protein fibres such as silk, where the enzymes can act on the fibres themselves over repeated use. Spot-test anything delicate or unfamiliar before you treat a visible area.
Which fabrics is it suitable for?
✓ Suitable for
✓ Cotton, denim and cotton blends
✓ Polyester, nylon, acrylic and other synthetic fibres
✓ Technical sportswear and synthetic activewear
✓ Lyocell, Tencel and modal
✓ Most everyday household textiles, including towels, bed linen, bibs and kids' clothes
Always follow the garment care label, particularly on technical fabrics with their own care instructions.
Which fabrics need a different approach?
⚠ Wool and other protein fibres
The enzymes in the formula can act on protein fibres themselves over repeated use, which shows up as gradual weakening or pilling. Use a detergent made for wool instead, and follow the garment care label.
Where you are not sure what the fibre is, treat it as unknown and spot-test first.
✓ For anything unfamiliar
If the care label is missing, the fibre is unknown, or the garment is delicate or sentimental, spot-test on a hidden seam before you treat the visible area. The three steps below cover it.
How do I spot-test?
✓ Spot-test in three steps
Spray a small amount on a hidden seam or an inside hem.
Leave it 5 to 10 minutes, rinse with cool water and pat dry.
Check for colour change, weakening or distortion. If the fabric looks and feels normal, treat the visible stain. On sentimental or expensive items, leave it 24 hours and check again first.
What if I used it on wool or silk by mistake?
⚠ What to do
Rinse the area straight away with cool water.
Handwash gently with a mild detergent made for delicates.
Keep it away from heat and the tumble dryer until the fabric looks and feels normal.
One accidental spray, rinsed promptly, is usually recoverable. It is repeated exposure that causes the trouble, so switch that garment to a detergent made for wool from here on.
Spray-on pre-treat for stubborn stains. Spray, wait 5 to 10 minutes, then wash as normal. Good Environmental Choice Australia (GECA) certified, Dermatest tested and Sensitive Choice approved.
