It’s always useful to look at the tool’s instruction manual as this may offer some specific advice. However, Wonkee Donkee has provided some general guidelines for brick rake maintenance.
Most brick rakes are made from aluminium because it is a lightweight and low maintenance material.
The best way to clean aluminium tools is to use the mildest cleaning product possible.
Use a brush with soft bristles to remove all dirt and dust from the tool.
To clean the brick rake, wipe the tool with a hot, damp cloth and a small amount of mild soap. Repeat until clean, and then dry thoroughly.
Aluminium should not rust as its surface is coated in aluminium oxide, which forms a barrier between the metal (aluminium) and any water / oxygen it comes into contact with.
Aluminium oxide, can however, build up and create a dull and milky surface to aluminium products; this is a type of corrosion. However, there is very little need to remove aluminium oxide build-up as this actually protects the tool from further corrosion.
If the wheels become stiff, lubricate them with a little tool oil after cleaning.
The tool’s robust pin can often get lost and replacement pins are not usually sold separately. However, you can insert an ordinary steel or masonry nail, which should work just as well.
Brick rakes have thick aluminium wheels which are designed to withstand being dragged over rough surfaces, but will wear with prolonged use. The tool is relatively inexpensive and so individual parts are not made to be replaced; instead it is advisable to buy a new brick rake.
Store your brick rake in a clean toolbox, preferably one with individual sections so as you can keep your brick rake away from other tools, preventing any damage.
