Can I use Stain Remover on carpets, rugs, or lounges?Updated 4 hours ago
TL;DR: Stain Remover is for laundry use only. It needs to be rinsed out in a full wash cycle, so it's not suitable for direct use on carpets, rugs, or lounges. For spot cleaning, use Sensitive Laundry Liquid in a spot cleaner or wet vac, or pre-treat with Stain Remover before running the machine.

Why not Stain Remover on its own?
⚠ Needs a full wash rinse
The enzymes and surfactants in Stain Remover are formulated to be rinsed away in a full machine wash cycle. Soft furnishings don't get the same deep rinse, so product residue can remain in the fibres and padding. Over time that residue can attract new dirt, cause faint odours, or mark darker patches as the fabric dries.
What should I use instead?
✓ Spot cleaner or wet vac method
Add 1 pump (4 mL) of Sensitive Laundry Liquid per 1L of warm water in the machine tank.
Run the spot cleaner over the stained area as the manufacturer recommends.
Allow the area to dry fully before walking or sitting on it.
✓ For heavier stains: pre-treat first
Pre-spray Stain Remover directly onto the fabric and let it dwell briefly before running the spot cleaner. The machine rinse step replaces the need for a full wash cycle.
This combination works because Stain Remover lifts the stain with concentrated enzymes, then the spot cleaner flushes both the stain and the residue away in one pass.
⚠ Fabric check
Avoid on: wool carpets and rugs, silk upholstery, and other protein-fibre soft furnishings.
Spot-test first on: leather, suede, viscose blends, and any fabric with a "dry clean only" label. Test on an inside edge or hidden section before treating a visible area.
