FWIW, red has not really got a good reputation. It seems fragile, and hard to clean from all the posts here.
Just in general, all is needed is a damp MF cloth; it seems that the more you use a "cleaner" or more advanced methods (including "conditioners"), the worse it is. I believe this is true in general, but it does seem the red is especially vulnerable.
I have always bought some expensive leather sofas for several years made in sweden.. The store that sells them is called Scan Design. They are high end. When I bought them the store told me to only use a microfiber cloth and diluted ivory liquid dishwashing soap solution, then wipe off with clean damp microfiber. This has always been my favorite. It will take off ink, blood, dirt, grime without hurting the leather. It works like a charm and never ever hurts the leather.
Try a very dilute "mix" of Ivory hand soap... about as gentle as it is going to get and leaves no film or other chemicals behind.
Many years ago one of the "Big Time" national car mags had an article on what to clean cars with and the guy writing it tried all his candidates on his contact lenses first (don't try this at home) and suggested Ivory for washing gentle articles.
But, admittedly, I don't know about red Vette interiors. I've only had (still have) one red leather interior in my life, made from real cows slaughtered decades ago, on which I only use Kiwi oxblood shoe polish (paste).
