WD-40 Specialist Contact Cleaner Spray 11 oz

WD-40 Specialist Contact Cleaner Spray, 11 oz. It is a WD40 product! I got this to clean sliding switches on some solar yard lights. It brought them back to life. If you have old fashioned mechanical switches, linear or rotary, this is what you need to keep them working at peak efficiency. It leaves no residue I can see (dries quickly), a little bit was enough, and just working the sliding switch on the solar light was enough to clean the switch contacts and revive the light. My lights have been working for a week now and that is with rain (light about .01 inch) and the sprinklers watering the lawn (95 degree + days). Good Stuff! Read more
