Good heavy duty detergent

I tested Tide Heavy Duty Laundry Detergent by throwing in tough linen and clothing that had been through a big cleaning and cats. Normally, these would require pre-cleaning before a wash. Tide Heavy Duty did a good job, the laundry came out clean, smelling fresh but not soapy or perfume-y, and I didn't use extra water or rinsing.

I won't use this for all of my laundry, but it's a good tool to have in my laundry arsenal for the tough stuff.
