Every monsoon, the same dark patches creep back: behind the wardrobe, along the bathroom ceiling, in the corners where damp settles. Tidy Fox Mould Remover is made for exactly these spots. The formula uses a 16% vinegar concentration, four times the strength of household vinegar, to break down mould and mildew where they grow instead of just hiding the stain. Use it right and it shows: spray until the patch is fully wet, leave it to work for 30 to 60 minutes, then wipe with a dry cloth. Old, deep set patches need a second round. There is a sharp vinegar smell while it works, so keep the room ventilated; it fades as the surface dries. Use it across the house: bathroom walls, tile joints, ceilings, wooden furniture, cupboard interiors, shoe racks and balcony walls. Once an area is clean, a light spray every week in damp season keeps regrowth away. Being bleach free, it will not leave pale patches on painted walls or wood. Avoid marble, granite and natural stone. In the box: one 1 litre bottle of Tidy Fox Vinegar Based Mould Remover with a trigger sprayer, in secure, leakproof packaging.
