Report graffiti to Bristol City Council:

or Fix My Street (which is forwarded to the council):

Please forward the confirmation email from Bristol City Council to so that we will be aware that the graffiti has been reported.
The council will usually (but not always) remove graffiti within a few days. Attaching a photo to your email would also be helpful.
It helps to get graffiti removed as soon as possible as one graffito tends to attract more.
