My vintage car (1925) has an 'West of England'wool headliner which is an deep red/ burgandy colour. It needs to be cleaned and freshened up as it is a little grubby and with two light water stain marks. Can you please recommend an product? Thank you.
So long as cold water is used, I'd be happy to use a wet vac with sprayer function, and a reasonable solution of woolite first, before moving to something more typical.
