There is nothing worse that seeing or even stepping in a pet accident. They're not just unsightly, but can also cause major odour problems down the road. These can cause your house to smell and let your friends and family in for a suprise when you open the door to welcome them with a waft or ammonia and bacteria to greet them.

Lets cut to the 'how to'. We need to break this into 2 parts; Fresh and Dry. These are the processes for each one. Remember this is a recommendation and first check any products recommended in an area that doesn't matter if it loses colour, like in a built in cupboard or an old off cut.

Fresh Pet Accidents

These are usually the easiest to remove.

1. Grab a lot of paper towel, at least 20 pieces and stack them.
2. Apply to the area. If it doesnt fit the area you may need to do this with 2 stacks of paper towel.
3. Place something heavy like a kettle bell, barbell weight or something that is going to apply equal pressure on the paper towel. Even a rock/brick on a handtowel in a frypan... yes it has been used before.
4. Leave it there for about an hour and repeat.

The results should be soaked paper towel that you just dispose of. Generally with small dogs and most cats you will only need to do this twice and the secondtime will have little residue in it. If it is a larger dog it can take up to 3 or 4 applications. 

Dry Pet Accidents

For dry accidents the steps are same... "but its dry!" I hear you say. Not for long. You will need a cup of warm, body temperature water and a small bottle of 3-6% peroxide from the chemist. Add about 50mls into a jug along with the cup of warm water. Pour it onto the pet accident slowly. You are trying to replicate the action of the pet creating the accident with a continuos small flow and body temperature water.

The next step is to wait 15 minutes to allow it to seep into the areas the urnine is at. The peroxide will start to destroy the bacteria aiding in odour control and also reversing staining caused by celluloise from the backing ior urochrome from the urine. This may froth and bubble a little bit. This is the peroxide reacting with proteins in the urine as well as bacteria.

Now do the steps that you would for a fresh pet accident.

Remember this is great to improve it, but it will never be as good as  a profesional carpet cleaner can achieve. If the odour is really bad and the stain persists, make sure that you contact your carpet cleaning professional.
