Mango Tree Flowering Season

[ignoranceisbliss 0]

My neighbour's mango tree flowers have left blotchy brown stains on my carpark tiles.

Have used chlorine but to no avail.

Any idea what detergent works and where to get those industrial cleaning agents for stubborn stains?

Another way is to use old cloth/ rag and soak it with the chlorine and put the soaked cloth onto the stain area, cover it for at least 30 min and see if works. Anyway, I notice that not all chlorine sold in supermarket are strong and powerful. Personally, I like Cloret brand, its a Japanese brand but expensive. Perhaps u can also try this brand
