WHAT OUR PARTNERS ARE SAYING
I’ve been in this industry for over 40 years, and I’ve never received the level of service, dedication, and superior products that I have received since partnering with MDG. Our entire salesforce is excited about the education and opportunities that our partnership has opened up for us to better supply our customers with products that actually work and are environmentally safer than the harsh chemicals we’ve previously provided.
LEVERAGING MICROBIAL-BASED CLEANERS
The CLEAR Answer to Tough Odors
Through innovative work in the lab, our microbiologists discovered that many market-leading ingredients just couldn’t tackle some of the most common—yet difficult-to-degrade—odor compounds found in I&I applications. After almost two years of dedicated research and development, we filled that marketplace gap this year with the launch of SporActiv® CLEAR. CLEAR is our latest I&Ifocused ingredient with newly discovered Bacillus strains that maximize odor reduction. Explore the CLEAR story below:
