Protects hammers from corrosion. Thumbs from hammers, you’re still on your own.
Whether you’re working construction or finishing a project around the house, having tools that last is vital for getting quality jobs done. Use a protective coat of WD-40 to make sure you can still hammer away at all of those hard tasks.
Cleans and lubricates hacksaw blades. Hockey masks too.
Keeping saw blades clean is not just a good idea – it’s often a necessity to ensure accurate cuts. Use WD-40 to keep blades “squeaky” clean and help you slice away with precision.
Removes rust from saws. Blood too. No questions asked.
Rust can be more than an eyesore – it can prevent tools from staying in working order. WD-40 is an excellent way to remove rust and prevent it from forming in the first place.
Prevents rust on outdoor air conditioners. Rust air stinks.
When it starts to get warm, air conditioners crank up and people take any measure necessary to stay cool. WD-40 can help keep you stay comfortable by making sure your air conditioners stay protected from the elements, and in good working order.
Removes roofing tar from circular saw blades. Hmm, dinosaurs could’ve used this stuff.
Roofing tar can be great on shingles, but a pain to get off of your tools. Use WD-40 to get that gunk off, so you are ready to take on the next job.
