Summarize the following:
There are a few different products you can try when it comes to removing cat urine from a mattress. Enzyme cleaners are specifically designed to break down organic matter like urine and blood. Use about ½ to a full cup (118 to 235 ml) of cleaner, depending on the size of the stain. You can also try a mixture of household cleaning products such as:  ¼ to ½ cup (59 to 118 ml) vinegar mixed with equal parts water (depending on the size of the stain ¼ to ½ cup (59 to 118 ml) hydrogen peroxide mixed with equal parts water and 1 teaspoon (5 ml) laundry detergent or stain remover Slowly pour the cleaner over the affected area, making sure you cover the entire stain. If you're using a cleaner in a spray bottle, remove the spray nozzle and pour the cleaner directly onto the stain. Spraying cleaner with a spray bottle will not penetrate the stain deeply enough, and won’t remove all the urine. Leave the cleaner to soak into the mattress for 15 minutes. This will give the cleaner time to work its way down into the mattress, penetrate the stain, and help break down the urine. After 15 minutes, take a couple of fresh towels and lay them over the stain on the mattress. Press them into the mattress to absorb excess cleaner, water, and urine. Continue blotting until you’ve absorbed all the moisture you can. Launder the dirty towels immediately. Sprinkle about ½ cup (110 g) of baking soda over the wet area. This will help draw out more moisture, and pull urine and cleaner odors out of the mattress. Letting the cleaner air dry in the mattress will give it the best chance of breaking down the urine and cleaning the mattress. If you were able to take your mattress outside, leave it out to dry in a covered and protected area where it won’t get dirty or wet from rain.  Inside, set up a fan and point it at the mattress to help speed up the drying time. The mattress may take two to three days to dry completely. To sleep on the mattress before it’s dry, cover the affected area with one or two towels, followed by a plastic bag. Make the bed as usual. Remove the towels in the morning to let the mattress continue air drying. Do NOT vacuum it up. Baking soda will pass through your vacuum's filters and end up in the motor. And then your vacuum will eventually die. When the baking soda has clumped together and absorbed all the liquid it can, use a brush or broom to clean it off the mattress. If the mattress is still wet, you can add more baking soda to keep drawing out moisture and odors.
Choose a cleaner. Saturate the stain with cleaner. Let the cleaner soak in. Absorb excess cleaner with towels. Sprinkle on some baking soda. Allow the remaining cleaner to air dry. Sweep or brush, the area to remove baking soda.
