I have an adjustment coming up on Friday, and noticed yesterday that my clear ligs are horribly stained after just 3 weeks. It's not that noticeable if one would just stand in front of me and talk to me... but I took a pic and zoomed in and yep... nice yellow tinge there.

I don't smoke; am not a coffee or tea drinker; I HATE curry, and although I have a Ramen addiction (I'm broke AND live in Hawaii, so I eat a ton of the stuff), I switched to one that does not have tumeric in it. So, I think the culprits for me have to be soda and ketchup. (Trying to just drink non-colored soft drinks, but I looooooove my Pepsi!)
I was wondering which foods and drinks stain ligs the WORST.
I am currently perusing the "Lig Colors" thread to get some ideas on possible lig colors (other than clear), but I thought I'd post my general question here.
Thanks-
Cathy
