The Microsave cavity liner is an excellent solution for minimising your microwave cleaning time. Designed to fit Panasonic NE1843 and NE1853 microwave ovens, the Microsave perfectly fits inside the cavity and prevents the interior of the machine getting contaminated by food residue. This also extends the lifespan of the microwave, protecting essential components such as lights, vents and plates. After a food service, simply slip out the Microsave and clean with washing-up liquid and warm water. Easy.Polypropylene
