Microwave splatters? The no-stress strategy for getting rid of those stubborn soup or sauce stains is to fill a heatproof mug with water and squeeze a lemon [calamansi works as well] into it, then microwave on high for 2 minutes. The steam from the water will break down the stuck-on mess while the lemon deodorizes. Then simply wipe down the appliance with a soapy sponge. You’ll be surprised how quickly you can wipe away those stains.
