There was a thread a few years back about yellow stains appearing on the concrete pool deck after the winter cover was removed. We have that and it gets worse every year. No one can figure out what it is.
 
Welcome to TFP! :wave: Sounds like perhaps residual moisture transfer from the pool up & under the edges of the cover. Perhaps. Other factors may come into play such as the cover material, type of decking, etc. But below are just two or many such discussions.
