Can I use Sensitive Laundry Liquid in a spot cleaner or wet vac?Updated 3 hours ago

TL;DR: Sensitive Laundry Liquid can be used in a spot cleaner or wet vac at 1 pump per tank. Pre-treat heavy stains by spraying Stain Remover directly on the fabric first. Always spot test upholstery before treating the full stain.

How do I use it in a spot cleaner?

Steps

1

Add 1 pump of Sensitive Laundry Liquid to your spot cleaner's water tank.

2

Run the machine over the stained area as normal.

3

For heavier stains, pre-spray Stain Remover directly onto the fabric first and allow it to dwell briefly before using the spot cleaner.

✓ Why it works well

  1 pump is a consistent, repeatable dose per tank

  Gentle enough for delicate upholstery fabrics

  Works in both wet vac and handheld spot cleaners

1 pump per tank Spot cleaners Wet vacs Upholstery safe

⚠ Before you start

  Spot test on a small, inconspicuous area first, especially on couches and rugs

  Use the minimum product needed, over-wetting fabric can cause watermarks

  If your spot cleaner has a rinse cycle, run it after treating to remove residue

Spot test first Don't over-saturate Rinse after treating

⚠ What about Universal Cleaner?

Universal Cleaner is a ready-to-use product and is not recommended for dilution or use in spot cleaning machines. Don't mix it with other products or adjust its concentration. For spot cleaning with a machine, use Sensitive Laundry Liquid.

Universal Cleaner not for spot cleaners Don't dilute Universal Cleaner

Should I pair it with Stain Remover?

✓ Pre-treat heavy stains

For set-in or high-protein stains (wine, blood, food, pet accidents), spray Stain Remover directly onto the fabric and let it dwell for a minute or two before running the spot cleaner. The enzymes in Stain Remover break down the stain so the spot cleaner has less work to do.
