Meaning and boundaries
Acid attack is broader than the GlassRenu category 'acid etch.' Different acids, concentrations, temperatures, exposure times, and glass compositions produce different effects.
Why it matters in glass restoration
Some acids mainly leach mobile ions, while others or acid-containing products can damage coatings or adjacent materials; product identification is essential.
