Buyer’s Guide: What to Consider

Choosing the right glass polish depends on your specific needs. Here are five key factors to consider before making your purchase.

• Scratch Depth: Determine if scratches are fine (barely feel with fingernail) or deep. Fine scratches need a polish; deep ones may require a scratch removal kit.
• Application Method: Some polishes work by hand, others need a drill or rotary polisher. Choose based on your available tools and comfort level.
• Type of Contaminant: Water spots, oil film, wiper marks, or old coatings each respond to different formulas. Cerium oxide polishes are great for hard water spots.
• Glass Surface: Ensure the polish is safe for your glass type—most are for automotive glass, but some also work on shower doors or aquarium glass.
• Ease of Use: Liquid polishes are often easier for beginners, while kits with pads and attachments may require more setup but offer better results.
