How to remove mould from silicone?

Mould on silicone joints is common in damp environments such as bathrooms and kitchens. Black or grey mould patches can be unsightly and difficult to remove. We recommend using a professional cleaning product specifically designed for this purpose. Our HG mould removers are effective for eliminating mould from silicone joints and other damp surfaces. Important: if mould has penetrated beneath the silicone, cleaning alone may not be sufficient and replacing the sealant is the only long-term solution. Always check the manufacturer's maintenance instructions first.

HG solutions for removing mould from silicone

We offer two effective HG solutions for removing mould from silicone joints and other damp surfaces. These products are designed to tackle mould and damp patches on joints, tiled walls and plasterwork in wet rooms.

• HG mould remover foam spray: The foam clings to the surface for longer, allowing a more effective treatment. It reduces splashing and has a less pungent odour. Suitable for tiled walls, plasterwork and silicone joints in bathrooms, showers, toilets and kitchens.
• HG mould spray: Instantly destroys mould on damp surfaces, both indoors and outdoors, and removes grey and black mould stains without scrubbing. The product works on tiled walls, silicone joints and plasterwork.

Solutions for removing mould from silicone

Mould on silicone can be tricky to shift, especially when it's dug deep into the joint. We recommend using a professional mould removal product specifically designed and approved for this type of soiling. General household cleaners are not advisable, as we cannot guarantee their effectiveness or safety on silicone. Always check the manufacturer's maintenance instructions for the surface beforehand.

• Apply a suitable mould remover according to instructions and allow sufficient contact time.
• Rinse afterwards with water and a sponge, without scrubbing hard.
• Repeat if necessary for stubborn mould patches.

If mould has penetrated deeply into or beneath the silicone joint, replacing the silicone joint is the only effective solution.

What causes mould to form on silicone?

Mould growth on silicone usually results from a combination of moisture and conditions where that moisture cannot escape properly. Silicone joints in wet rooms are therefore particularly prone to mould growth.

• Prolonged moisture exposure, for example in bathrooms, showers and kitchens.
• Poor ventilation, allowing moisture to linger.
• Build-up of dirt and residues on silicone joints.
• Ageing or deteriorating sealant.

To prevent new mould growth as far as possible, we recommend the following: ensure good ventilation in damp areas by opening windows or using mechanical ventilation, clean silicone joints regularly and dry them after use, check joints for wear and replace them in good time if needed, and always follow the manufacturer's maintenance instructions for the materials you use.
