Will the colorant in COMBOTHERM™ stain concrete, carpets or interior floors?

The colorant in COMBOTHERM™ is present in very small quantities. It tends to dilute and disperse quickly upon contact with snow and ice. The colorant is water-washable, nontoxic and biodegradable. Product testing prior to launch found no indication of colorant tracking when white carpet was placed just inside an entranceway where the product was applied. No problems with colorant staining of concrete have been reported.
