Teräsharjat

Teräsharjat are cleaning tools made of stiff wire bristles, typically steel. They are commonly used for aggressive cleaning tasks where lighter brushes would be ineffective. The wire bristles are designed to effectively remove rust, paint, scale, and other stubborn debris from a variety of surfaces.

The construction of a teräsharja usually involves a handle, often made of wood or plastic, to which a metal head containing the wire bristles is attached. The bristles can be arranged in different patterns, such as straight rows or tufted, depending on the intended application. The wire itself can vary in thickness and material, with stainless steel being common for rust resistance and brass or bronze sometimes used for softer metals to prevent scratching.

Teräsharjat find widespread use in both industrial and domestic settings. In workshops and construction sites, they are employed for preparing metal surfaces before painting or welding, cleaning tools and machinery, and removing concrete or mortar residue. Homeowners might use them for tasks like cleaning barbecue grills, garden tools, or de-rusting metal garden furniture. It is important to use teräsharjat with appropriate safety precautions, such as wearing gloves and eye protection, as the wire bristles can be sharp and may break off during use.
