Answer: Poly methylmethacrylate acrylate (PMMA) is compatible with alkaline detergents like Solujet. PMMA is labile to strong oxidizing agents. Alcojet and Detojet contain small amounts of active chlorine oxidizing agents. At the high pH of these cleaners, the oxidizing agent is pretty stable and is not that strong an oxidizer, so a rapid attack is not expected on PMMA, but given sufficient time and temperature, expect to eventually see some effect from Alcojet and Detojet on PMMA.
