Welcome to our forum.
I use 303 Protectant made for vinyl and I find it pretty affordable in Marine stores. If you buy it at a hot tub store it can cost twice as much as if you buy it at Marine store. Armo all works, but you will hear people swear it dries out the vinyl and is like crack, but the people that make it deny that of course.
You can use saddle soap as well. My cover manufacturer and my hot tub installer do not recommend using Armor All. The guy who installed mine says he uses saddle soap on his own. He says that 303 works well too.

Some time ago, and I think it may have even been posted here, someone emailed Aromorall and asked about it being used on spa covers. Their response was basically that they were unfamiliar with the specific type of vinyl used in spa covers and weren't able to recommend their product for use on them.
