What was the name of the old bar soap (from the 50s and 60s) that was used for everything, especially laundry?

I believe you are looking for Sunlight Soap. It seems to me it was made by Lever Bros. We used it for everything, including bath time with scratched knees elbows etc along with"Dettol". This was all during WW11 and it sure worked for large families as the soap stayed fairly hard but still gave up a good "sapple" or "suds". Never disolved into a mush. I never knew anyone who didn't use it until I emmigrated in 1951 but it was familiar and we still used in in Canada along with most folk we knew at that time - probably into the 70's & 80's.

Old Soap Brands

You are probably looking for Fels Naptha; Lava soap works quite well for a number of applications, as does Bon Ami (in the bar). You can still buy all three of these ate my local supermarket ... no self-respecting mechanic's shop would be without Lava soap.

they didn't have soap in the 50's and 60's. Soap wasn't invented until 1977 when a chimp named Rocko accidentally gave a cat a bath.

I'm not sure if I am spelling the product right....but I believe it was called something like "Fells-Napa". It was a bar of soap you scrubbed your laundry with. Grandma used to use it.

I use soap on a rope-guys got the wrong idea when I lived in the dorms yes you can be my bar of soap-guess what I wash first?

Blue soap or Sunlight Soap was used in RSA according to my dear old Mom.

Ivory, Oxydol, Borax, Palmolive, or Lux? There was also one called Chipso laundry detergent.

Fels Naptha or Zote
