How do I use Stain Remover?Updated 2 hours ago
TL;DR: Fill Foaming Spray Bottle with Stain Remover, spray directly onto the stain, wait 5 to 10 minutes, lightly brush if needed, then wash as normal. For best results, treat stains as soon as they happen and don't let them dry.

How do I use it step by step?
✓ Steps 1 to 3
Pour Stain Remover into Foaming Spray Bottle.

Wash as normal according to the garment care label.
✓ For tricky stains
Treat as soon as possible. If you can't wash straight away, keep the area damp and reapply before washing. Repeat the spray, wait, wash cycle if needed rather than overusing product.
⚠ Fabric check
Avoid on: wool, silk, cashmere, alpaca, and other protein fibres. The protease enzyme can weaken these fabrics over repeated use.
