Tide from 30 years ago had phosphates in it. It worked great on oil stains and the like. We used it at the service station I worked about 36 years ago to clean the garage floor every night. Worked great. Then the phosphates were removed and it never worked quite as well again. But, hopefully the environment is a little safer.
