Rewoquat W3690 PG is a surfactant that can be used for chemical fossil preparation. Acid-free chemical extraction. Suitable for removing marly matrix from calcitic fossils. Dilute as required with isopropanol (typically 3-4 parts Rewoquat to 1 part isopropanol). Use mechanical preparation methods to expose as much of the fossil as possible. Then leave in a sealed container. Keep checking every few hours. Rinse thoroughly and repeatedly with water after application until no foam forms.
We recommend purchasing some Isopropanol too as this product requires dilution before use.
