Long story short....a leather sofa and chair was left on a backporch and was rained on.What is going to happen to the leather once it dries? Is it ruined or can it be treated and look decent again?Any information is greatly appreciated.
Make sure that the frame and springs (if there are any) are not also wet. Once the leather has completely dried rub in some pure bees wax and it will restore it to near what it was.
Bad luck Biro ink is a tough one to solve, Very artistic is she?? Yep there are solutions you can by in most supermarkets specific to biro ink but before you use it in earnest try it on the leather in an unobtrusive place ,some of those solvents can be very rough and may effect the surface of the leather if not the colour. You said you had tried cleaning solution did you mean a specialist leather cleaner? they are available from quality furniture stores or maybe upholsterers. Very best of luck and hid the pens or alternatively bind her hands.xx
It depends how good the leather is if it will dry and crack. Allow the sofa and chair to dry naturally don't use any heat. If there is no cracking buy some mink oil from a shoe repair store and apply to leather to resoften it up. If the colour has came out patchy you can also buy a shoe dye and recolour the sofa. Good luck.
