Pingi Classic bags can be recharged in the microwave oven, but not directly on the metal grate or metal microwave floor. This is due to heat development and the microwave interior not always being clean. Place Pingi in a clean microwave-safe dish (f.e. PYREX). Optionally a double-folded kitchen paper can be placed under Pingiwhile recharging to retain excessive moisture.
Please note models ASB-1000 and DSB-600 are not suitable for microwave recharging.
