How often do I need to clean up the new rug I just bought?
When it comes to cleaning rugs, everyone has their timeline. If you have lots of time, you can probably manage at least once weekly for a proper clean. If your work life takes over, though, you might only find time for bi-weekly or monthly cleaning. The least you should do is give it a proper clean down and brush once per month.
Of course, if you are stuck on time, I think you might benefit from hiring a professional. I have used professional carpet cleaning companies like AA Carpet Cleaners a few times and always ensured that my carpet looks the part. It is easier to get rid of rug stains, carpet damage, etc.
But yes, you should aim for at least bi-weekly if you have the time and monthly at a minimum.
