The Faithfull heavy-duty narrow-headed Grout Scrubbing Brush is fitted with stiff nylon bristles and is suitable for use on all tiled surfaces. It is ideal for tackling stubborn grime, mildew and other forms of residue in hard-to-reach places and tight grout lines. A large soft-grip handle provides extra user comfort. It may be used in conjunction with most tile and grout cleaning detergent. The handle unscrews to allow use of a longer handle such as FAIPATPOLE. How to use:Thoroughly clean the tiled area with a suitable cleaner and allow to dry. Spray the grout with a grout cleaner and allow 3 to 5 minutes to penetrate, but do not allow to dry. Use the special narrow brush head to track the groove allowing maximum bristle contact with the grout. Wipe clean with a damp cloth to ensure no dirt is washed back over into the grout grooves. For best results polish with a dry cloth.  Additional Information:• Tool Type: Grout Rake
