What not to put in the dishwasher

The wrong approach to dishwashing is harmful to your health, pots and dishwasher.

1. Knives

Hot water dulls the knives. In addition, the flow of liquid under pressure can send them on a fascinating journey through the innards of the dishwasher, and the blades will ruin nearby objects or the unit itself. So if the device does not have a special compartment for instruments, you will have to wash the knives by hand.

2. Aluminum cookware

In a dishwasher, everything works against aluminum dishes. Long exposure to hot water and detergent will oxidize the metal. The dishwasher usually uses alkaline liquids and tablets to effectively dissolve food leftovers. They also do a great job with the top layer of dishes. So it is better to wash aluminum pots and pans by hand so as not to turn them into disposable ones.

3. Cast iron cookware

Cast iron is not aluminum. This is a solid material, if not for centuries, then for years. Cookware made of this metal acquires its properties due to hardening during production and the formation of a protective fat layer during cooking. In the dishwasher, the cast iron loses its coating. And although the frying pan will look the same, after that it will be possible to use it only for self-defense purposes.

4. Wooden dishes

Due to the high temperature of the water, you run the risk of putting a whole wooden board or bowl in the dishwasher, and getting a cracked one. If the machine has a delicate mode, you can use it to avoid an unfortunate outcome. But the easiest way is to rinse wood products with your hands.

5. Thermoses and thermo mugs

The hot water jets in the dishwasher easily damage the insulating materials and turn the thermo mug into a simple mug. But if you still don't want to wash the dishes with your hands, then just look for products from this category that have a mark that allows you to use the dishwasher.

6. Crockery with intricate shapes

You can, of course, put a meat grinder or garlic press in the dishwasher and hope for a miracle. But, most likely, everything will have to be washed with your hands, since the unit is not able to remove the stuck food pieces. So putting such items in the dishwasher is not prohibited, but pointless.

7. Dishes with labels

Dishwasher-safe jars and cups will do the trick: hot water will peel the labels off. But pieces of paper will clog the filters and may damage the device. Subsequent renovations will hurt the budget.

8. Dishes with burnt food residues

Alas, you will have to scrub the burnt food by hand: the dishwasher will not cope with it.

9. Graceful wine glasses

Water is supplied to the dishwasher under pressure, which the glasses may simply not withstand and crack. By themselves or through collisions with pallet neighbors. So it is worth either washing them with your hands, or drinking wine from mugs that will endure indelicate handling.

10. Crystal

Hot water can cause the crystal to tarnish and crack. True, modern salad bowls and glasses are made more dishwasher-friendly. The relevant information must be indicated on the packaging.

11. Silver and copper products

Cookware may become tarnished and stained. And cleaning it will obviously take longer than washing it by hand.

12. Service with gilding

It is better not to put the elegant tea pair, inherited from your great-grandmother, in the dishwasher. Tableware may lose gilding and hand-painted elements.

13. Pottery without glaze

Clay is absorbent. In the dishwasher, it will absorb the detergent along with the water. The liquid will then evaporate, and the corrosive substances will remain.

14. Cracked or stuck cookware

If someone from your family is not ready to part with an old cracked mug, then a guaranteed way to get rid of it is to put it in the dishwasher. The main thing is to be careful when you start removing the pile of shards from the device.

15. Pet bowls

In 67% of pet bowls, Salmonella persists even after a standard dishwasher cycle. Accordingly, bacteria can settle in the device, from where they go to the plates for people. So forget about dishwashing your pet bowls if you value your health.
