Title Charlie's Soap Out Cleans Leading Brands
Test
by Jessica, Chickaominy Middle School, Hanover, VA The three cleaners tested were Charlie's Soap - All Purpose,
409 and a generic Food Lion cleaner. Red fruit juice was used to stain three
squares of carpet for each of the three cleaners: a total of nine squares. The
researcher treated three carpet squares per cleaner for each cleaner and allowed
the cleaners to soak in for 5 minutes. Then each carpet square was scrubbed
with a rag for 2 minutes. The average amount cleaned for each brand of cleaning
agent greatest to least is Charlie's Soap-5, Food Lion-3, and 409 Carpet-4.
