Here are some tips on cleaning glass and vinyl surfaces:

Glass:

• Use soap and water or glass cleaner, such as Windex
• Soak any droppings or bug splatters; do not use a razor blade or chisel to remove
• Wipe entire surface and until dry to avoid seeing missed spots in the sun

Vinyl:

• Use regular soap and water; avoid abrasive cleansers, such as comet and vim
• Feel free to buff into any scuffs as just soap and water will cause no damage
