Dear Museum L I am in search of someone who can recommend a good way to remove tire track residue off of limestone and cast concrete. We have an outdoor sculpture piece that has a large amount of black marks that I need to remove from the work. Any suggestions would be greatly appreciated! Thank you in advance.
