Dear Listmembers, The Biblioteca de Catalunya in Barcelona (Spain) has been using Nitty Gritty cleaning fluids Pure1 (78 rpm) and Pure2 (vinyls) and machines for many years, with pretty good results. In addition to our experience, our Preservation team is trying to gather all recommendations regarding the process of cleaning, and we'd very much appreciate yours. We are not quite satisfied with Nitty Gritty services in Spain, so we stopped buying them. Our cleaning machine is now Clearaudio SMART MATRIX, but we still used Nitty Gritty fluids, applied manually on the discs surface. We gathered many information from specialised bibliography. Nitty Gritty in the USA kindky sent to us the components of both fluids Pure 1 and 2. But we would like to ask ARSC members about their experience in cleaning old 78's, acetates, lacquer discs and vinyls. In orther not to bother the list with this, you could send the answers to the e-mail stated below. Many thanks in advance, Margarida Ullate i Estanyol Fonoteca Biblioteca de Catalunya Hospital, 56 08001 Barcelona +34 93270 2300 (2166) [log in to unmask]
