How to remove the smell of cat urine from pillows, sofas and quilts?

I tried, but it didn't work. I bought ammonia water with washing powder, added ammonia water and washing powder water, put it in a basin where I rubbed my urine, and then washed sofa cover normally in the washing machine. The sofa sponge has to be washed and dried, and the effect is very good, but the smell of ammonia water is too exciting, so I have to wear a mask and protective glasses.
