Patio caked in bird poo

MouldyOldDough

Our patio is absolutely caked in bird poo - small white patches that now all join

We have tried a scrubbing brush and hot water but it won't shift

Any suggestions ?

We cant use any chemiicals due to the colour of the stones and mortar - according to the warranty instructions

The wife thinks that it is just efforvescenvce leatching from the stones but I have seen the guls doing their business on it and it it is not over the whole patio - just a flightpath !

Try one of the dedicated patio/driveway cleaners, or, washing up liquid and a brush, then hose off..

We tried a stiff brush and washing up liquid - but it wouldnt shift

And chemicals cant be used because of the waranty

Its also "loose fill" mortar - so pressure washers are not advised

You have a warranty.  Is there an address, telephone number or website on it?  Do you know who cuts/manufactures the stones?

You need to contact them directly as this cannot be an unknown problem to them and they should be able to offer you advice.
