Water and milk stains on suede couch?

Okay so we got a dark green suede couch a couple of months ago but my toddlers keep getting onto it with their sippy cups and water/milk will leak out on occasion. I'll clean the spots up the best I can with a rag but when it dries, there's obvious rings on the couch where the liquid was. Is there a product I can use to remove these spots or is my couch done for?
