What to do if the balcony floor is yellowed by flower fertilizer

It's good to get a little hydrochloric acid clearly, if you don't have hydrochloric acid, you can get some vinegar, it's just that the time is slower, those are some substances such as calcium bicarbonate or calcium carbonate, which are easy to remove.

Distinguish what kind of material the floor is made of, and treat it differently.

If it is a stone material, it can be carefully cleaned with clean water and necessary detergents under normal circumstances;

If you need a special maintenance agent for wood materials, you can consult and buy them in the building materials market.

There should be no way about this, you try to wipe it with water to see if you can wipe it off, if you can't wipe it off, it means that it has penetrated into the inner layer, and if it penetrates, there is no way, only replacement!! Hope it helps!

Get a little hydrochloric acid, oxalic acid, sulfuric acid, vinegar, bleaching powder, etc., just clean it, but the time is slow. Those who brush it with a brush and wait for a while are good, sulfuric acid is not recommended to use Oh, this is careful to disfigure! It is very easy to wash it with a weak acid brush.

You can try it with oxalic acid. Pour oxalic acid over the yellowed area, wait a few minutes, and then brush it off with a brush. Finally, rinse with clean water.

If there is a stain on the floor or is stained with some stain, the best thing to do is to get some hydrochloric acid, or oxalic acid, which you really can't try with vinegar and banana water. Then wash with a steel wool ball or a brush.

Try it with bleaching powder.

If that doesn't work otherwise, you can try using sulfuric acid, but you have to be careful.

Try washing the floor with an appropriate amount of laundry detergent or bleach.

Eat the flowers or eat the floor.
