I agree.
Replace the shoes and just use Brakleen Brake Parts Cleaner or something like it to clean the drums.
In one of the dealerships I worked at had a roll around brake cleaner station. It was a small parts cleaner station sat on a barrel like the ones you see at Harbor Freight. They wanted us to use it to cut back on costs of Brakleen. I liked it, it worked well.
I have not worked at a dealer in over 25 years.
