JULY, 1970 Vol . 33 P. 269·304 No. 7 , ;. ----- 57TH A NUAL MEETING August 17, 18, 19, 20, 1970 Roosevelt Motor Hotel Cedar Rapids, Iowa There's a story in that half-shot pot you're looking at. A food processor we know had just about given up on his aluminum bean pots. Accumulated food stains were uncleanable. Or so he thought until a Pennwalt representative showed him what Pennwalt pot cleaners could do. A quick soak and rinse did the job. Do you have a cleaning problem with plant utensils and equipment? Chances are Pennwalt has a cleaning process to solve your problem immediately. And if we don't, your Pennwalt representative will put our chemical research staff to work until we do have the solution. And no halfway measures about it. Contact us now. You have nothing to lose but your stains.
