Can I use Stain Remover on carpets or rugs?Updated 5 days ago

TL;DR: Stain Remover is for laundry use only. It needs a full wash rinse, so it's not suitable for direct use on carpets, rugs, or lounges. For spot cleaning soft furnishings, use Sensitive Laundry Liquid in a spot cleaner or wet vac. For heavier stains, pre-treat with Stain Remover before running the machine.

Can I use Stain Remover on carpets or rugs?

Stain Remover is 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. For carpets, rugs, and lounges, use Sensitive Laundry Liquid in a spot cleaner or wet vac instead.

Laundry use only Needs full wash rinse Residue can re-soil

What should I use instead?

For carpets, rugs, and lounges, use Sensitive Laundry Liquid in a spot cleaner or wet vac at 1 pump per 1L of warm water in the machine tank. For heavier stains, pre-spray Stain Remover directly onto the fabric, let it sit for 5 to 10 minutes, then run the spot cleaner. The machine rinse step handles what a full wash cycle would normally provide. Avoid Stain Remover on wool, silk, cashmere, alpaca, and mohair, and spot-test first on leather, suede, and any unfamiliar fabric.

✓ Spot cleaner or wet vac method

1

Add 1 pump (4 mL) of Sensitive Laundry Liquid per 1L of warm water in the machine tank.

2

Run the spot cleaner over the stained area as the manufacturer recommends.

3

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 sit for 5 to 10 minutes before running the spot cleaner. The spot cleaner's rinse step handles what a full wash cycle would normally provide for laundry.

Pre-treat Wait 5 to 10 mins Then spot clean

⚠ Fabric check

Avoid Stain Remover on wool, silk, cashmere, alpaca, and mohair carpets, rugs, and upholstery. The enzymes can act on these fibres over repeated use. See the fabric compatibility article for the full list and what to use instead.

For non-fabric upholstery materials like leather and suede, and for any unfamiliar fabric, spot-test on a hidden edge or inside seam first. Colourfastness varies by dye and material.

Not for delicate fibres Spot-test leather and suede Results vary
