If wicker pattern celluloid film accidentally gets liquids like coffee or juice on a tabletop, what should I do immediately? Will it cause the texture to discolor or dissolve?

Immediately absorb the liquid with a dry cloth and then gently wipe with warm water. Generally, it will not cause the texture to change color or dissolve. Celluloid film has a certain resistance to liquids, but do not use strong solvents such as alcohol, and do not let liquids remain for a long time.
