Can Stain Remover cause colour change on fabric?Updated 4 hours ago
TL;DR: Stain Remover is bleach-free, but some fabrics can still experience colour change depending on how the dye was applied during manufacturing. Always spot test first.

Why can colour change still happen?
✓ Bleach-free, enzyme-based
Stain Remover doesn't contain chlorine or oxygen bleach. It uses enzymes and surfactants to lift stains at a molecular level, which is why the formula is classified as colour-safe on properly dyed fabrics.
⚠ Colour loss from the fabric
In some cases, lighter patches or fading can appear after treatment. This is usually due to colour loss from the fabric itself, rather than bleaching caused by the product. Fabric dyes vary widely, and some are less stable than others.
⚠ More likely if
✓ The dye was not fully fixed during garment manufacturing
✓ The fabric is highly dyed, dark, or brightly coloured
✓ The garment already had wear, fading, or heat exposure
How do I reduce the risk?
✓ Reduce the risk
✓ Spot test on an inside seam where the fabric is layered at the stitching
✓ Follow the garment care label. Never treat a "dry clean only" garment at home
✓ Don't leave the product on longer than directed (5 to 15 minutes)
✓ Rinse and wash thoroughly after treatment. Don't let the product dry on the fabric
How do I spot-test for colourfastness?
✓ 3-step spot test
Apply a small amount to a hidden seam or inside hem.
Wait 5 to 10 minutes, then blot with a white cloth. If you see dye transfer onto the cloth, the fabric isn't colourfast.
Rinse the test area, let it dry, and check against the rest of the garment. If it looks and feels unchanged, you're good to treat the stain.
