X‑Wash Bio: The Plant-Based Cleaner Formerly Known as Novasol S2 DS
At Rittagraf, we now offer X‑Wash Bio, the new name for the well-known Novasol S2 DS. This is a vegetable-based, ecological cleaning oil designed specifically for printmaking. It’s widely used to clean rollers, brayers, plates, tools and work surfaces in techniques such as intaglio, relief, photopolymer (Toyobo), letterpress, lithography and offset printing.
Why Choose X‑Wash Bio?
This product was originally formulated by FujiFilm for industrial printing, later adopted by artists and printmakers as a sustainable and effective studio cleaner. It is now distributed by Rittagraf, continuing its legacy under the name X‑Wash Bio.
Unlike conventional petroleum-based cleaners, X‑Wash Bio offers a safe, eco-friendly alternative without compromising on cleaning performance. It is ideal for maintaining tools, cleaning inking rollers and preparing photopolymer plates (e.g. Toyobo) without risk to health or the environment.
What is X‑Wash Bio?
X‑Wash Bio is a biodegradable, non-toxic cleaner formulated from plant-based oils. Its degreasing power makes it ideal for cleaning oil-based inks and greasy residues without using traditional solvents. This makes it a safe alternative for printmaking studios, classrooms and shared workshops.
