If your mattress smells due to someone urinating on it, use a fabric neutralizer like Febreeze, allow it to dry and then place dryer sheets on top of the mattress. Keep dryer sheets between the mattress and the sheets until odour dissipates. You can also use a pet-order removal product and then using a hairdryer to dry the mattress.
If there is a chemical smell on your mattress due to cleaning or sanitizing, the dryer sheet tip will work in a pinch, as well.
Do not apply materials like bleach to your mattress because it will seep into the folds of fabric and irritate your skin while you are sleeping. If you are experiencing discomfort or an allergic reaction from your mattress, discard it and do not continue sleeping on it. Although you can have your mattress cleaned professionally, make sure the cleaners do not use harsh chemicals to get your mattress clean. Harsh chemicals may make your mattress smell even worse, and can irritate your skin
It is always best to turn a mattress at least twice a year- side over side, then side over side again and then head over toe.
Follow these instructions and your mattress will stay good as new!
