The writing is in Yiddish, which uses Hebrew characters and a German syntax. The last line apparently says "produkten." Any other intepretations would be greatly welcomed.

According to Moshe Rappoport from Zurich in a recent e-mail to me,

"Apparently (I can't make out the first letter very clearly) it says "Scouring Powder Products". That would be like Ajax or Comet white powder cleanser products for washing dishes and pots. Since it was used with food it would have had to have been Kosher.  Do they still sell those tubular cans? "

Yes Moshe! Still tubular. Thanks for the update!
