Thermal shock: Pouring boiling water directly onto cold surfaces can cause cracks in the plastic lining or, worse, damage hidden pipes. Use very hot but not boiling water (about 140-160°F/60–70°C) and always in containers.
Moisture in electrical components: If water enters cracks, grilles, or vents, it can cause malfunctions or oxidation. Keep water in a spray bottle, basin, or soaked cloth, without direct spills.
Excessive salt use: Small amounts of dissolved salt won’t harm anything, but it shouldn’t be sprinkled pure on interior surfaces, as it could damage seals or plastic over time. Always dissolve salt in water; don’t use it “dry.”
