When it gets hot, windows roll down, air conditioners crank up and
people take any measure necessary to stay cool. WD-40 can help keep
you comfortable during the sweltering summer heat. Try it to:

-Lubricate fan spindles and bearings

-Penetrate stuck bolts on air conditioning units when doing repairs

-Prevent rust from forming on swamp coolers

-Stop squeaks on and lubricate window cranks and locks

-Un-stick buttons on air conditioner control units
