I have a microfiber couch and chair and need to know how to get stains out.?

It is oyster in color and my 2 year old has completely stained it up and the people tell me not to scrub it only blot it with the cleaner but its not working for me. The fabric comes off can I wash in machine or what do I do its only 5 months old and I'm really upset with how it looks. Please help me!!!
