More than €1.2m has been spent by Dublin City Council on removing graffiti since 2010.
Now Fianna Fail councillor Jim O'Callaghan has said prisoners on Community Return Programmes should be deployed to clean it up.
"There should be a greater focus on the use of community service orders under the Community Return Programme so that much of this high expenditure can be redirected to deal with the homelessness crisis in the city," he said.
The council is currently undertaking a review of its Litter Management Plan with a focus on the cost of graffiti removal.
This led Mr O'Callaghan to ask the council's chief executive how much had been spent on cleaning up such vandalism in each year between 2010 and 2014.
"The exorbitant cost of removing graffiti is simply too high when council resources are limited and there's a chronic homelessness crisis in the city," he said.
"As part of the current review being undertaken by the council into its litter management plan, I am urging a greater use of the Community Return Programme as a way of reducing the cost of removing graffiti."
Mr O'Callaghan added that carefully selected prisoners may be granted "reviewable temporary release with a requirement to do unpaid community service work such as graffiti removal in a supervised setting".
