Removing asphalt from metal silo's

[WashRite 14]

Does anyone have experience in removing asphalt from painted metal. What chemicals are typically used?

Customer has two silo's and a catwalk that need cleaning. They had this cleaned two years ago and want it done again. Silo's have old paint and may well need painting in the next 6-12 months. Customer not concerned with paint. This is an asphalt plant. Asphalt is stored in the silo's.

This is a rush job. Customer called today and wants quote tomorrow. Job starts Wednesday. Any help would be appreciated.
