About Us

Jefco, Inc. dba Mrs. Stewart's Bluing

What began in 1883 with Al Stewart, a midwest peddler of Mrs. Stewart's® Bluing, is now the country’s best way to keep white clothing looking it's whitest and to restore dingy whites to bright white!

Mrs. Stewart's® Bluing
" . . . for over 140 years, the most effective, safe,
versatile, economical, environmentally friendly
laundry whitener available." 

... has become our slogan and explains quite well what is important to most consumers and what is important to us. We have a good quality, time-tested product, have been family-owned since the beginning, boast of the best customer service, value old-fashioned integrity ... just like Mrs. Stewart once did.
