Water Spots vs Etching: What’s the Difference?

A water spot is a mineral deposit left on top of the surface when water dries. Etching is damage into the surface itself, and water spots left too long can turn into etching. Surface spots can be removed by hand with a water spot remover like Sud Factory’s Dissolve X2, no buffer needed. If a mark won’t come off after directed short passes (~30 seconds each, and do not let it dry), the stain is ingrained into the clear coat. On glass it’s different: if the glass is etched, Spotless X2 can take it out.

The difference

• Water spots: minerals left behind when hard water or sprinkler water dries. They sit on the surface.
• Etching: damage into the surface, not something sitting on it. Water spots left too long can turn into etching.

Etching on glass

If the glass is etched, Spotless X2 can take it out. Use it as directed on the windshield page. If you can feel a chip or crack with your fingernail, that isn’t etching; have a glass shop look at it. Spotless X2 is for glass only, so keep it off paint and clear coat.

How to tell which you have

1. Wash and dry the panel so you’re looking at a clean surface.
2. Treat one small section with a water spot remover, following the directions below.
3. If the spot is gone, it was a surface deposit.
4. If a ring is still there, make another short pass (~30 seconds) and do not let it dry. If it still won’t come off, the stain is ingrained into the clear coat.

1. Wash first. Wash and rinse off loose dirt. Grit plus pressure is what scratches.
2. Work cool and shaded. Use a cool panel, out of direct sun.
3. Apply to the pad, not the paint. Put a small amount on a microfiber applicator pad or towel.
4. Work one small section. Wipe it over the spots with light pressure.
5. Wipe, rinse, dry. Wipe clean with a damp microfiber, rinse, and dry.
6. Second pass if needed. If a ring is still there, make another short pass with Dissolve X2 (~30 seconds) and do not let it dry. If it still won’t come off, the stain is ingrained into the clear coat.
7. Protect. Apply SFX1 right away (up to 12 months of protection).
