Testing Red Painted Surfaces
Background:
LeadCheck Swabs turn pink to red when lead is detected. It is important, when testing surfaces
painted with red paint, to make sure that red pigment will not bleed from the paint surface
onto the Swab tip.
Method:
Using a white cloth, clean red surfaces with a few drops of distilled white vinegar. If
the cloth turns pink or red use Sodium Sulfide to test the surface for the presence of lead.
