Dirty old bags

[Pseudonymity]

I've got a couple of bags. One is a Mulberry in suede (what on earth possessed me?) and another is black leather which has collected drips of coffee/general scum over the years . What do people recommend re. cleaning? Is there a particular leather cream that people use? I'm worried about transfer to clothes.

I use Collonil leather gel, but also recently heard about this company who will revive your handbag.. the handbag spa..might be worth a try?

I also use colonil products on my mulberry

thanks!
