Bernd, if you do not have an extractor, you could use a "wet or dry" vacuum. Over here we call them "Shop vacs." They are inexpensive but can handle liquid spills and come in many sizes. I think Rick described a protocol for urine spots and stains in another thread last week. The main thing is to treat pet urine areas deeply enough to really get them.
With Respect,
