Our take on the 14 oz (400g) 99% Cerium Oxide Glass Polishing Powder (7-9 Um) – Removes: Oil Films, Water Spots, Swirl Marks, Wiper Streaks, Removes Fine Scratches & Deep-Cleans Glass Surfaces.

SafeCope cerium oxide polishing powder is a 99% cerium oxide abrasive at 7–9 micron grit, sold as a 14 oz (400 g) tub. Mixed with water into a slurry, it works on glass only: windshields, windows, shower doors, aquarium glass, mirrors and glass panels. It targets water spots, oil film, wiper streaks, haze and light scratches, and needs firm pressure for at least 10 minutes per area. Against ready-made glass polishes it asks more of you — mixing, keeping the surface wet, and a hard pad or wool wheel — but the concentrated powder goes much further and the fine grit leaves fewer marks than coarser compounds.

Pros
  • 99% cerium oxide at a fine 7–9 micron grit
  • Works on water spots, oil film, wiper streaks, haze and light scratches
  • Can be applied by hand or with a rotary or dual-action polisher
  • Mixes with plain water, so no separate carrier liquid is needed
  • Large 400 g tub covers many polishing sessions
Cons
  • Powder must be mixed into a slurry before every use
  • Glass only — not for plastic, acrylic or painted surfaces
  • Needs firm pressure and at least 10 minutes per area for best results
  • Surface must be kept wet throughout, which takes attention
  • Glass must be cleaned of grit first or you risk new scratches

About the 14 oz (400g) 99% Cerium Oxide Glass Polishing Powder (7-9 Um) – Removes: Oil Films, Water Spots, Swirl Marks, Wiper Streaks, Removes Fine Scratches & Deep-Cleans Glass Surfaces.

This is a cerium oxide glass polishing powder, sold as 14 oz (400 g) at 99% purity with a 7-9 micron particle size. It removes light scratches, water spots, oil film, wiper marks, and haze from glass, and helps restore clarity. It also reduces hard water stains and mineral deposits.

It is for glass surfaces such as car windshields and windows, shower doors, aquarium glass, mirrors, and household glass panels. It is not recommended for plastic, acrylic, or painted surfaces.

The product is a powder, not a ready-to-use liquid. Mix it with clean water into a smooth slurry. Clean the glass first to remove dust, sand, grease, and debris, which helps prevent extra scratches. Apply the slurry with a hard sponge, felt pad, polishing pad, or wool wheel, and spread it evenly. Keep the surface slightly wet by adding a little clean water as needed. Polish with moderate to firm pressure for at least 10 minutes. You can polish by hand or with a rotary machine at about 500-2500 RPM.

Questions and answers

Will it remove deep scratches from a windshield?
It is aimed at light scratches, haze, water spots and wiper streaks. Deep scratches that catch a fingernail usually need a coarser compound or professional work.
How do I mix it?
Stir the powder into clean water until it forms a smooth slurry with no lumps. Add water as you polish to keep the surface slightly wet.
Can I use it on plastic headlights or acrylic?
No. It is for glass surfaces only; plastic, acrylic and painted surfaces are not recommended.
Can I use a machine polisher?
Yes. Apply the slurry with a hard sponge, felt pad, polishing pad or wool wheel, by hand or on a machine, with moderate to firm pressure.
How long should I polish each area?
Plan on several minutes, and at least 10 minutes, so the cerium oxide can fully work the glass.
What is in the tub?
A 14 oz (400 g) tub of 99% cerium oxide polishing powder at 7–9 micron grit. Water and an applicator pad are not included.
