I have never found anything that removes urine from fabric. If so, I would like to know !!

Try a combination of detergent, Oxyclean (I prefer the liquid), and the cat litter additive I posted earlier in this thread. This combo has taken out both the stain and odor of cat urine from clothing for me. If it's really bad, try running it through the washer twice with this combo.

All pet shops have a urine remover spray. It's commonly used on carpets. It takes a product that breaks down enzymes to remove the urine odor.

Lestoil works extremely well even on old grease stains. It smells horrible so I wash the item a lot after the Lestoil, but the grease is gone!

I use the product Awesome on most stains. Also, a Vet tech told me to use peroxide to remove blood stains. It has worked well for me.

I was told club soda for blood, coffee, tea and wine stains but haven't tried it yet. I use Grandma's stain remover. But will now check out some of the suggestions here

I haven't found a product that works for all but I like Oda Ban and Grandmas Spot Remover.

I have used Oxy spray on all my clothing stains...seems to work on almost all...expecially blood. I also used it to clean the grout on my bathroom floor and was happy with that too.

I just saw CLR has come out with new products that sounds like it covers most of your list. I like clr for calcium remover.

I have used "Fantastic" for years and keep a bottle of it under my kitchen sink. It cleans up spills on the kitchen floor, can be used on the carpet with no ill effects, takes the grease/good from the tracks on my sliding windows and doors, makes the bathroom floor sparkle, takes smudges off door jambs; so I guess I'll stick with it.

AWESOME I found at Big Lots too.. Love this stuff... and don't forget Dawn Dish soap...
