I looked at my dish dryer for a long time. It is metal, bought in an economy class store. The quality is appropriate. Since the dryer is constantly in contact with moisture, after a while our interior item was covered with an unpleasant red coating. I tried to wash it with water and a washcloth, but what's the point: the coating only increased and loose rust appeared. In the picture there is only a fragment of the lattice, in order to be able to take a closer look at how it looked.
Once upon a time on the Internet I read that in this situation, the water-acetic composition can help well in combination with hydrogen peroxide, in which the processed object is completely immersed. For such a procedure, at least twelve hours are needed. In our house to put out of action a much-needed thing for twelve hours is a disaster. So they reached out to vacation, having waited until everyone was scattered.
What did i need
I did not remember the exact proportions of the prescription, but I did it this way: I poured half a liter bottle of vinegar and half a 100 ml bottle of three percent peroxide into five liters of water (it was packaged in pharmacies in this container). The solution was in a wide basin, where she placed her rusty “beauty”. Since only the lower part of the grate was damaged, such an amount of liquid was sufficient.
12 hours have passed. After I took out the dryer from the basin, I was very upset: all the rust was in place. From frustration, she took a sponge and dishwashing detergent. Imagine my surprise when everything was very easily washed, only at the junction of the twigs I had to brush a little with an old toothbrush. The procedure took fifteen minutes (no more). Judge for yourself how great it turned out. Of course, if you look closely, you can see rare small black dots in those places where there was loose corrosion. Perhaps you should look for some other effective remedy.
Well, for now, it seems that our “assistant” has found a second life and will serve its masters a little more (before the next purge).
By the way, the same solution can be used several times. In it, I managed to wash a shelf of the same metal, the bottom of a galvanized bucket and metal parts of the mixer.
I hope that my experience will be useful to someone.
