Wall mould vs shower silicone mould: which product for which job

This is the question that saves you a wasted purchase. Mould on a painted wall and mould in shower silicone are two different problems that need two different products. Painted surfaces: the Wall Cleaner removes mould on contact. Grout and silicone: the Clove & Eucalyptus Mould Spray is built to reach into porous material. Using the wrong one is the most common reason people feel let down.

Which product do I use for which mould?

Match the product to the surface, every time. For mould on painted, hard, non-porous surfaces — walls, ceilings, painted timber like doors, wardrobes and beams, painted bathroom surfaces, caravan interiors — use the All Natural Mould Remover Wall Cleaner. For mould in tile grout, on tiles and in flexible shower silicone, use the Clove & Eucalyptus Mould Spray. That's the whole decision. It matters because these surfaces behave differently: on paint, mould sits on the surface and wipes away; in grout and silicone, it works its way into the material where a surface wipe can't follow. We deliberately make two products rather than pretending one bottle covers everything — because the honest answer is that it can't.

Why can't one product do both jobs?

Because "removing mould" means something physically different on each surface. A painted wall is sealed and non-porous, so the growth is largely on top; the Wall Cleaner's citric acid and clove oil lift it on contact as you wipe, and the black comes away. Porous grout and rubbery silicone absorb moisture and hold mould within the material, so wiping the surface never reaches the growth underneath — you need a spray formulated to penetrate and act at the root in that material, which is a different job and a different formulation. A product optimised to wipe mould off paint isn't optimised to penetrate silicone, and one built to reach into silicone isn't the right feel on a painted wall. It's the same reason you don't use tile grout sealer as wall paint: related problem, genuinely different material.

Painted walls: what the Wall Cleaner does

On painted surfaces the Wall Cleaner is straightforward and its result is a true, allowed claim: spray directly onto the mould, wipe off immediately with a damp cloth, and the mould is removed on contact — visibly, onto the cloth. It's bleach-free, paint safe, and pet and child safe, with no fumes, which is why it suits bedrooms, bathrooms and ceilings. Citric acid strips the surface minerals mould needs, and pure clove oil — a documented natural antifungal, with eugenol as its main compound (Pinto et al., 2009, Journal of Medical Microbiology) — acts on the mould directly.

Grout, tile and silicone: what the Mould Spray does (and the honest limit)

For porous bathroom surfaces the Clove & Eucalyptus Mould Spray is the right tool — it's designed to kill mould at the root in grout and silicone. But here's the honesty we won't skip, because it's exactly where people get oversold: on old silicone, deep black staining can remain in the material even after the mould itself is killed. The spray addresses the living growth and the recurrence; it does not bleach years of staining back to white, and we won't imply it does. The real win on silicone is relief from mould coming back, not a like-new cosmetic restoration. If your silicone is stained beyond what killing the mould resolves, sometimes the honest answer is that the silicone itself needs replacing — and we'd rather tell you that than sell you a false promise.

Which product for which surface

What if my bathroom has both?

Most do — a painted ceiling and walls plus tiled, siliconed wet areas. Use the Wall Cleaner on the painted ceiling and walls, and the Mould Spray on the grout and silicone. Plenty of people keep both on hand for exactly this reason, and there are bundles that pair them. It's not upselling for its own sake; it's that a bathroom genuinely presents two different surfaces, and each has its right tool.

I'm Tony Taig, fifth generation in a family that's distilled eucalyptus oil in Australia since 1895. It would be easier to market one "does everything" bottle. We make two honest products instead, and we tell you plainly where each one's job ends — including that silicone staining is sometimes there to stay.

Frequently asked questions

Which product do I use for wall mould vs shower silicone mould?

For mould on painted walls, ceilings and painted timber, use the All Natural Mould Remover Wall Cleaner. For mould in grout, tile and shower silicone, use the Clove & Eucalyptus Mould Spray, which is designed for porous surfaces.

Why can't one product do both jobs?

Painted surfaces hold mould on top, so it's removed on contact by wiping. Porous grout and silicone hold growth deeper, needing a product formulated to reach into the material. Different surfaces, different chemistry.

Will the Mould Spray make my old silicone look new again?

No. It kills mould at the root in the silicone, but deep black staining can remain in old silicone even after the mould is dealt with. The honest win is relief from recurrence, not visual restoration.

My bathroom has mould on both the painted ceiling and the silicone — what do I do?

Use the Wall Cleaner on the painted ceiling and walls, and the Mould Spray on the grout and silicone. Many people keep both for exactly this reason.
