Against the solid backing brackets and shelves may be secured, their arrangement being altered as occasion demands. It also admits of tacking the draperies in a substantial manner, and there is a satisfaction in knowing your window is solid and that any fragile articles displayed are perfectly safe.
HOW TO WASH WINDOWS.
A clean window pane is a necessity in a show window. Nothing destroys the attractiveness of a really good display so readily and effectively as a streaked, flyspecked glass in front of it.
Many merchants dread window washing day. It shouldn’t be a bugbear when a simple method like the following is understood. Wait until the sun is off the window, for if the sun is shining on the glass it will look streaked after drying, irrespective of the amount of muscle expended in the rubbing. Dust the window thoroughly, inside and out, and don’t touch the glass until after the inside woodwork has been cleansed. Use nothing but warm water, mixed with sufficient ammonia in washing the glass. Steer clear of soap. Dry the windows with the rubber cleaner or soft cotton cloth. Linen leaves lint on the glass. Polish with paper; that’s all that’s necessary.
TO PREVENT WINDOWS FROM FROSTING.
One of the merchant’s greatest trials is the sweating and frosting of windows in cold weather, rendering them useless for display purposes at the very season when they are most valuable.
Much has been written concerning methods of prevention of frost, but most of them are theoretical, and, while they work well in some instances, are absolute failures in others.
THE CAUSE.
Scientists will tell you that the reason a window sweats is because there is an uneven temperature on the opposite sides of the window pane. The cold air outside chills the pane, which condenses the moisture in the warm air inside as it strikes the glass, and the moisture is deposited in the form of “sweat” upon the inner surface of the glass. It then freezes, producing “frost.” Occasionally, when there is moisture in the outer air, a deposit is also made upon the outer surface of the glass, but in either case the frost arises from the uneven temperature of the air inside and outside the window glass.
