A pair of vintage cleaning products, looks to be from around 1950. Both have great graphics.
The Dutch Cleanser required a can opener to make openings to make openings to use the cleanser. Seems to be like Comet or other abrasive cleaners. It is still about a third full.
Please note that Sani-Flush is poison. They had warning labels in the long ago. Despite all the warning labels today the POISON label seems to be rare.. The good news it that it will not harm your septic system. There is just a tiny bit of the product left inside.
