1. The garbage disposal, food waste disposal, or “garburator”, was invented in 1927 by a Wisconsin architect who created InSinkErator.
2. The first mechanical dishwasher was registered in 1850 in the United States by Joel Houghton. This device was made of wood and was cranked by hand while water sprayed onto the dishes. This device was both slow and unreliable. Another patent granted to L.A. Alexander in 1865 was similar to the first but featured a hand-cranked rack system. Neither was practical or widely accepted.
3. William Shepphard patented liquid soap on August 22, 1865. Minnetonka Corporation introduced the first modern liquid soap and cornered the market by buying up the entire supply of the plastic pumps needed for the liquid soap dispensers.
