So, put on your cleaning gloves, wear a mask and follow these quick steps to clean the mess for good.
Clean the area frequently to avoid bird droppings from drying and becoming difficult to clean.
Make a solution. Mix 1 part bleach and 9 parts water in a bucket.
Pour it over. Soak the area with bleach solution and leave it undisturbed for at least 10 minutes.
Scrape it. Using an old mop or a wiper, scrape the droppings from the floor. If they show any resistance, pour some more solution and clean them.
Dispose of correctly. Collect the dirt in a dustpan and dispose it in a garbage bag properly.
Final cleaning. Pour some warm water and sprinkle Surf Excel detergent all over. Rinse it completely to get rid of the stench.
