Unfortunately, due to EPA regulations, Professional Chem-Dip carb cleaner product (part #0905) was discontinued earlier this year due to its methylene chloride content.  We recently introduced two new offerings (part #1904) & (part &1904C).  These are professional-grade immersion cleaners with almost zero odor and a much more favorable toxicological profile.    If you are interested in purchasing this product, please write to us via the Contact Us form in the MORE menu option.  We can try to find a retailer in your area who can supply it for you.  Also, please provide your city & state.
