A composition and methods for using the composition in removing processing byproducts is provided. The composition can be non-aqueous or semi-aqueous. The non-aqueous composition includes a non-aqueous solvent and one or more components including a fluoride compound and a pyridine compound. The semi-aqueous composition includes glacial acetic acid and one or more components including a fluoride compound and a pyridine compound. The composition can be used in removing processing byproducts from substrate assembly, including MRAM devices, that include at least a metal containing region and processing byproducts, where removing the processing byproducts includes exposing the substrate assembly to the composition for a time effective to remove at least a portion of the processing byproducts.
