Dishwasher leaving scratch marks on china
We have all seen the black or grey scratch marks on the base of our cups and mugs and never been really sure what it is or where it comes from. This is not a fault with your dishwasher though, but can be caused by the simple act of stirring your coffee!
If the surface of the cup or plate is scratched by cutlery there is a always the possibility that the surface can become damaged overtime, when these grey scratch marks can become apparent.
This is obviously very common when you think about a tea spoon in a cup or mug, more or less every time you have a hot drink, you will need to stir it!
You should bear in mind that aluminium utensils are far more likely to cause this type of surface damage.
Unfortunately, there is no cure for this problem, and once an item has been marked, there is nothing you can do to remove it. The only option is to replace the damaged item and avoid aluminium.
When loading your dishwasher, try to avoid any china items from coming into contact with the cutlery basket. Careful loading can help to cut down on a lot of unnecessary contact between items.
