MARBLE STAINS, LIMESTONE STAINS, ACID MARKS:
Marble and limestone are materials that will be etched from the acid content of wine, fruit juice, etc. It will also etch from acidic cleaners, including our acidic cleaners. Etching creates a dull patch in the otherwise smooth, somewhat glossy finish.
For cleaning of limestone and marble surfaces, Aldon has a non-acidic cleaner, "Insta-Clean" that can safely clean these materials without etching.
Any Aldon cleaner has more than one purpose. It is not limited to only this cleaning project.
