How to Clean Plastic Window Frames

Cleaning your window panes is a quick fix to brightening up your windows, but will do little to lend your home a sparkling clean appearance if they are surrounded by dirty and grimy window frames.

Plastic frames can scratch more easily than aluminium, so it is important to take care when cleaning them not to damage the frame.

Follow a few quick tips to help lessen your frustration when cleaning your plastic window frames.
