"Ozzie and Harriet" made its TV debut this day in 1952. One day David and Ricky were asked to wash windows at the Nelson household. One of the brothers grabbed the window spray and the other some paper towels. But before they could start, Ozzie said, "Not so fast, boys. There's a right and wrong way to wash windows." He told the boys they'd need a good solution to wash with. Then he mixed a teaspoon of liquid dish detergent in 2 gallons of warm water. And he said they'd need a good scrubber. He produced a big sponge. Ozzie told his sons to soak the surface to loosen dirt and to scrub enough to wash it off. Next he introduced the squeegee, the tool that finishes things. The secret he told the boys is to buy a good one -- about a foot wide. And most important, one with a good fresh rubber blade. And that's the On The House Tip for today.
