The wife and I have three rats - they're great pets and overall pretty inexpensive to keep. Fabric bedding is a popular choice for rodents like rats and guinea pigs, and our girls seem to love their fleece-lined house. Overall it's saved us loads on bedding - we bought a few fleece blankets from the thrift store to turn into their hammocks, then just do a small load of laundry each week. For the first year this worked perfectly, we just changed the blankets every 3 days or so, when they started to get smelly. Overtime though, the scent seems to have caught in the fabric. They come out freshly laundered but then within one day have a strong smell. Any advice for getting the scent out? We tried soaking in vinegar and then washing with a bit of baking soda, but that didn't change anything (and we have to use a scent-free powder detergent so as not to cause them breathing issues). It's just a small cost, but I would rather not spend another $10 on new blankets if we can refresh the old ones.
