Why is my Stain Remover cloudy or yellow?Updated 5 hours ago
TL;DR: A slight yellow tint or mild cloudiness in Stain Remover is normal, safe to use, and doesn't affect cleaning performance.
Last reviewed: April 2026
Why does it happen?
✓ Natural formula variation
Natural variation in enzymes and surfactants can give the liquid a faint yellow tone or a little haze. Temperature swings during storage or delivery can also make the formula look cloudy until it settles. We make Stain Remover without added dyes or colour stabilisers, so what you see is the unaltered formula.
What should I do?
✓ Quick fix
Shake gently to remix.
Let it come back to room temperature, then shake again.
If you want extra peace of mind, do a quick spot test on a hidden seam before treating the stain.
What's normal vs concerning?
✓ Normal looks like
✓ Faint yellow to pale straw tint
✓ Slight haze or cloudiness that clears after shaking
✓ Mild, neutral scent from the enzyme blend
✓ Slight variation in tone between bottles
⚠ When to get in touch
! Strong, foul, or off smell
! Separation that won't remix after warming and shaking
! Visible contamination or particles floating in the liquid
! Damaged packaging or a leaking bottle on arrival
