What is a pet odor removal solution that i can make at home?

My puppy has peed in a couple of spots and nothing will seem to get rid of the odor.

I foster dogs, so always have accident spots. Oxy Clean spray works every time! The stains don't come back. If you are making your own, I would use a water/bleach solution for tile and hardwood, and use lemon juice/water/dish soap for carpets. Try the oxy clean though, you will love it!

Baking sodoa works really well. you have to rubb it in and let it set for about and hour then wipe it up with a damp towel. some times you have to do it twice though. this works on carpets

white vinegar removes smells

a mixture of peroxide and a little bit of dishsoap. the bubbly peroxide has lifting and "eating" action. Get an empty spraybottle and add like 90% peroxide and 10% dishsoap. Spray. Scrub. Let sit. Blot up.

All the other solutions you've been given should work, I like the Oxyclean myself, but NEVER use ammonia. It will make the smell worse!Happy cleaning.
