Thanks a lot for above two responses.



Yes, it is perhaps the case: the water is very hard and has full of

high mineral content....that will be OK if there is no harm for people

living with me.



However, why David E. Ross loves bricks with different amounts of

minerals? Are you an artist? Can you find anything beautifull from the

picture I attached?

No, I'm not an artist.



The flower pot in the photo looks okay. It appears that the plant is

well established and not newly planted. The pot also looks unique, not

like a million other pots fresh from the nursery.



When reusing an old pot, I do remove the mineral crusts that form on

it.

Leaves resting on those crusts are sometimes damaged by the minerals.

In my area, the crusts can also be too salty for many plants. But I do

leave the stains left behind when the crusts are removed.



If the stains bother you, try wiping them with a rag soaked with

vinegar.

Thanks a lot for your helps, I will try to use vinegar but I need to buy

a bottle of vinegar

You actually don't NEED vinegar (a weak acid) but can scrub off the white stuff with a kitchen abrasive pad.

However, if you DO get vinegar, allow me to pass on an unrelated usage: I have a terrible habit of forgetting small tools, like [secaturs - Brit talk] [pruning shears - US talk] after working in the garden. So they are out in the dew, get rusty; eventuallyI find them.

I fill a tall glass with vinegar and leave the wounded tool (opened) maybe overnight. Easy to clean off next day and oil. And swear to never again..
