We rent.
My chihuahua has had a few accidents
Carpet is a light beige so its easy to see.

Getting rid of carpet stains that reappear after I clean them?

I’ve used a heavy duty carpet cleaner, steam mop w/ the carpet attachment, pretty much all the carpet cleaning solutions (expensive, cheap, & in between carpet cleaners), and nothing has worked. Sometimes the stain will go away and then reappear just like it was before in a few days. What gives?! What’s your best carpet stain cleaning advice?

Cleaned the carpet and 1 day later when the carpet is drying it is smelling up the whole house???

We cleaned the carpet with one of those bulky carpet cleaners and even used special pet soap stuff and we cleaned the carpet and there were a lot of pet stains from my dog.

Im talking really bad….its so bad its smelling up the whole house. How do I get rid of this smell????? It is driving all of us crazy! Any suggestions?
