Do I need to use Laundry Pump?Updated 5 hours ago

TL;DR: No, you do not have to. Laundry Pump is the quickest way to get a precise 4 ml dose every press, but Laundry Dosing Cup measures the same doses by hand. What matters is dosing accurately, because Sensitive Laundry Liquid is concentrated.

Do I need to use Laundry Pump?

No, Laundry Pump is not required. It is the quickest way to dose Sensitive Laundry Liquid because each full press delivers exactly 4 ml, so there is no measuring or pouring. If you would rather measure by hand, Laundry Dosing Cup is a silicone cup with marked lines at 24 ml and 40 ml on the inside. It is heat-proof, safe if it ends up in the dryer, and can go through the wash to clean itself. Either tool gives you the accuracy that a concentrated detergent needs, so pick whichever suits how you like to dose.

Each full press delivers exactly 4 ml, so there is no measuring or pouring. Six presses for a normal load, ten for a large or heavily soiled one. Pump straight into the drawer or into the cup.

4 ml per press No measuring Around 3,000 presses

Why does accurate dosing matter?

Sensitive Laundry Liquid is concentrated, so a small amount cleans a full load. Pouring by eye tends to overshoot. Too much detergent can leave residue on clothes and make rinsing less effective, which is worth avoiding on sensitive skin. Too little and clothes do not come out properly clean. Either Laundry Pump or Laundry Dosing Cup gives you the accuracy to hit the right dose every load. For a heavy mark, pre-treat the spot with Stain Remover rather than raising the dose for the whole load.

Do not pour by eye

Treat the mark, not the load

For a heavy mark, pre-treat the spot with Stain Remover rather than raising the dose for the whole load.

Pre-treat spots Keep the dose steady

How many presses does a load need?

Each full press is 4 ml. A small or lightly soiled load takes 4 presses, which is 16 ml. A normal load takes 6 presses, which is 24 ml. A large or heavily soiled load takes 10 presses, which is 40 ml. Dose to the size of the load rather than the maximum capacity of your machine, because a half-full 10 kg drum is still a normal load. If you are using Laundry Dosing Cup instead, fill to the 24 ml marker for a normal load or the 40 ml marker for a large one.

Small load

4 presses. Use for a small or lightly soiled load.

4 presses 16 ml

Normal load

6 presses, or fill Laundry Dosing Cup to the 24 ml marker.

6 presses 24 ml

Large or heavily soiled

10 presses, or fill the cup to the 40 ml marker. Dose to load size, not drum capacity.

10 presses 40 ml
