Yes, a dried stain can still be removed!
A dried stain can solely be removed using a James stain remover, whilst fresh stains can often be removed using tap water. Therefore, it is wise to immediately start treatment by placing a damp cotton cloth on the stain.
A dried or persistent stain can be treated using James Stainwonder or James Stainspray. For this purpose, follow the instructions from the stain solutions menu where more than 1200 stain solutions are provided.
For instance, a red wine stain from a half year ago can be easily removed, but only if no other treatment has been performed.
