STAIN REMOVER

Gentle refers to what it does to the fabric, not to the stain. It's built for stubborn oil-based marks — sunscreen, sebum, foundation, cosmetics — and for the yellowing that builds where you sweat. It handles everyday stains — food, ball-pen marks, dirt — as a matter of course. See the care guide to watch it work on real stains.

Yes. Two reasons, both structural.

The first is pH. Silk sits at around 5.5, wool and cashmere around 6 — and so does The Treatment. Protein fibres hold their shape and sheen best near their own pH. Many stain removers run more alkaline than that, and alkalinity is what lifts the scales on a wool fibre and dulls the lustre in silk over time.

The second is that there are no enzymes in the formula. Many laundry products use them to break stains down — protease especially, which works by breaking apart protein. They're effective, but protease can't tell a stain protein from a fibre protein. Wool, silk, and cashmere are protein fibres, so the same reaction that lifts the stain can act on your delicates too.

Thus, both low-pH and enzyme-free rule out the reactions that damage protein fibres in the first place. That's why the pieces you'd normally send out to dry cleaners can be treated at home instead.

No. This formula doesn't have bleach, hydrogen peroxide, or optical brighteners.

Oxidising agents such as bleach or peroxide work by destroying colour, not by lifting the stains off — they break the part of the molecule that absorbs light, so the stain stops being visible while most of what caused it stays in the fibre until it washes out. Effective, but that reaction doesn't tell the difference between the stain, the dye underneath, and the fibre itself.

On protein fibres like wool and silk, it goes further. Oxidation works on the bonds holding the fibre together — weakening it, and dulling the sheen and softness that made the piece worth keeping. That kind of damage is structural, so it doesn't wash out.

We left them completely out. The Treatment works the other way round: active surfactants surround the mark and release it from the fibre so it rinses away intact. You'll see it disperse as you work it in — not fading, but dispersing. The reaction is designed to break the bond between stain and fibre, leaving the dye and the fibre structure itself untouched. That's what makes it gentler on anything you'd want to keep wearing.

Not quite. It needs a moment of contact: spray, work it in gently, then rinse or wash.

What you'll see is the mark disperse and lift as you work it in, rather than vanish on the spot the way bleach does. Anything that makes a stain disappear instantly is often bleaching the colour out of it.

The Treatment works the other way — it releases the stain from the fibre so it leaves with the rinse. See the care guide for the full method.

We'll be straightforward. It's low-pH, enzyme-free, and free of brightening agents, so it works differently on different marks. Tannin-based stains — red wine, berries — respond, but they're not what this formula was primarily optimized for; those often need enzymes or oxidation to fully break down, and we left both out on purpose to avoid possible damage to fabrics or colours.

Where it goes hardest is what it's built for: foundation, cosmetics, sebum, oil, and the yellowing that builds where you sweat. The care guide shows how to treat each of these yourself, at home, with real results — and we keep it updated as customers tell us what they're working on.
