Hm, I reckon the best thing to do is spray it with some spray that you can get at the shops which desposes of the smell, buy a new couch or use a chemical that you can look up to burn the smell away.
Tell the fat guy that is sitting on it to have a shower.
If you have a zippered couch cushion, I would unzip it and put it into the washing machine on cold and let it line dry. You can always use Febreeze to make it smell better.
Put dog outside where they belong and buy a new couch, because urine has ammonia in it and the smell will never go away only fade. Well actually....you can use 1 part vinegar to 2 parts water. Vinegar will remove the enzymes that make the urine smell, oh that would be the ammonia, and the smell will go. You will need to keep the dog away from the couch until it is clean and dry though, and then make sure it does not happen again.
clean it
Febreeze works. Just test it on a small unnoticeable part of the couch first to check and see it it will stain your couch. If it doesn't then spray the couch, especially the cushions.
make her have a bath of vanilla essense
Clean it.
spit on it
Clean the couch with a mixture of vinegar and Pine Sol. That should remove the smell and the stain. D-Molish Now also does a great job of removing the smell and the soaked urine.
yes
Baby powder.
put spray or purfume on.
the simplest way to remove static from your couch or any other place is by simply taking a few of your fabric softener sheets that you may use for laundry and just rub them all over the couch. Not only will it remove the static it'll make it smell good too!
