An aqueous breaking fluid having an aqueous fluid, powder particles, and at least one reducing sugar may be helpful in degrading a polymeric filter cake downhole. The aqueous breaking fluid may be introduced through a wellbore. The aqueous fluid may be or include water, brine, acid, alcohol, a mutual solvent, and mixtures thereof. A coating material of each metallic powder particle may be disintegrated such that the particle core may be released from the powder particle. The aqueous breaking fluid, which may include the reducing sugar and the released particle core, may contact and degrade the polymeric filter cake.
