Its very easy to use. It has a locking mechanism, i just twist the tip of the bottle. I spray the mould and leave for few minutes. Its very powerful, it removes the mould quickly and it has long effect.

Un producto muy eficaz frente al moho. Su fragancia es lejía. Su envase con pistola dosificadora lo hace muy cómodo de manejar. Sirve para cualquier superficie, excepto textiles. Yo por seguridad lo mantengo fuera del alcance de los niños,ya que es un producto muy fuerte. Relación calidad precio buenísima

My bathroom curtain got a little moldy, I washed it with detergent but it didn't work. Today I sprayed with Cillit Bang and in a few minutes it was completely clean. I use all the timp this when moulding appears on the bathroom. Definitely recommend it.
