Can I use Sensitive Laundry Liquid in a spot cleaner or wet vac?Updated 8 hours ago

TL;DR: Add 1 pump of Sensitive Laundry Liquid per tank in a spot cleaner or wet vac. For a heavy stain, pre-spray Stain Remover on the fabric first. Spot test upholstery and rugs somewhere out of sight before you treat the whole area.

Can I use Sensitive Laundry Liquid in a spot cleaner or wet vac?

Koh Sensitive Laundry Liquid works in a spot cleaner or wet vac at 1 pump per tank. Add 1 pump to the clean-water tank, fill with water as usual, then run the machine over the area following its own instructions. Spot test upholstery, rugs and carpet somewhere out of sight first, and use the least product that does the job.

How to use it

1

Add 1 pump of Sensitive Laundry Liquid to the clean-water tank.

2

Fill with water as usual and run the machine over the area, following your machine's own instructions.

3

If your machine has a rinse cycle, run it afterwards to lift what's left in the fibres.

✓ Why 1 pump per tank

A pump of the Laundry Pump is 4 mL, so 1 pump gives you the same dose every tank without guessing. There's no added fragrance and no dyes in the formula, which matters more on a couch than in a machine, because nothing is left behind to smell of afterwards.

Universal Cleaner is ready to use and belongs on a cloth, not in a tank. Use Sensitive Laundry Liquid for spot cleaning machines.


What should I check before I start?

Spot test on a small area out of sight first, on couches and rugs especially, and check for colour change or a shift in texture. Use the least product that does the job, because over-wetting fabric leaves watermarks and takes a long time to dry.

⚠ Three checks worth two minutes

1

Spot test somewhere out of sight. The back of a cushion or under a skirt. Look for colour change and for any shift in the texture once it dries.

2

Use the least product that works. Over-wetting fabric leaves watermarks and takes a long time to dry, and neither of those is easy to undo.

3

Read the furniture's own care code. Upholstery carries a cleaning code, and where it says water is a problem, it wins over anything here.

Spot test first Do not over-wet Rinse after

Should I pair it with Stain Remover?

For a set-in or protein-based stain like wine, blood, food or a pet accident, pre-treat first. Decant Koh Stain Remover into a foaming bottle, spray the stain, leave it 5 to 10 minutes, then run the spot cleaner with Sensitive Laundry Liquid in the tank. On a light or fresh mark the liquid alone is usually enough.

✓ Pre-treat the stain, then extract it

For a set-in or protein-based stain, wine, blood, food or a pet accident, do the targeted work first. Stain Remover goes into a foaming bottle, then you spray the stain, leave it 5 to 10 minutes and run the spot cleaner over it with Sensitive Laundry Liquid in the tank. Treat the mark fresh where you can. On a light or fresh mark, the liquid alone is usually enough.

5 to 10 minutes Treat fresh Spot test first
