Hi, so we're renting this apartment, and unfortunately the birds like to sit along the concrete wall of the balcony and poo everywhere.
I clean it regularly but lately there's been some marks that I can't remove. As you can see, the concrete has a stupid texture and it's painted so I'm trying not to be too rough with it.
I've tried hot water with dishwashing liquid and a scrubbing brush but it just won't come out.
Are there any good products that can help with this?
I don't own a pressure washer and I don't really want to get one solely for this purpose.
Thanks.
Hi @laura2989,
You might like to add a couple of tablespoons of baking soda to your water and dishwashing liquid mix. Allow the mixture to sit for ten minutes before agitating with a toothbrush.
Another option is to use a solution of equal parts vinegar and water. Or you can even try some Selleys 300g RP7 No Loss Straw Lubricant. With any of these solutions, I recommend trying them in an inconspicuous location to ensure they don't damage or stain the paintwork.
Please let me know if you have any questions.
Mitchell
