How to properly clean up water stains in Handmade Sink :
First, you'll need a small bowl of white vinegar.
Then, wipe the place that needs to be cleaned, and then use a cloth dampened with white vinegar to tightly wrap the gap. Then lightly pour the white vinegar onto the cloth so that the dirt is fully soaked in the vinegar. Then wait an hour.
After an hour, take out the sponge brush and wipe the area to be cleaned.
You will find that it gradually becomes clean! But there are still some places that cannot be removed.
That's okay, do it again, wrap a strip of vinegar-soaked cloth over the area that needs to be cleaned, and wait another hour. Then wipe it with a sponge brush to see if it can be wiped off?
Finally, wipe off the excess moisture and that's it, your sink looks brand new!
