I have Bluestone interior floors in new construction. Ready to finish but slight paint overspray and several glue spots. Is there a problem using a diluted muriatic acid to clean?

Which type of bluestone do you have? It ranges in toughness from basalt to limestone: en.wikipedia.org/wiki/Bluestone – Wayfaring Stranger Sep 22 '13 at 1:28
What kind of paint? – HerrBag Sep 23 '13 at 19:59
Just be sure to test your chosen method on a inconspicuous portion before diving in on your favorite part. – Trout Jun 21 '14 at 2:04

Muriatic could be a bit harsh, causing a 'bleached' spot. Many natural stones are sensitive to acids, most being alkaline (from types of limestone).

A "citrus" paint stripper could be less harsh, but it is acidic, also.

I would use ammonia and a soft nylon hand brush, alternating after rinses with a mild detergent.
