Can you put a rag with shoe polish or polyurethane on it in the washer to clean?
Answers:
Used water doesn't just run into rivers from your house. It ends up in waste treatment plants, but what is in the wash water goes with it. However, polyurethane dries to a hard finish and will not be washed off in the washer. As for shoe polish, there is wax in the mixture that will coat your washer and transfer to subsequent loads. Why bother. Rags are cheap. You can get them at Home Depot for next to nothing.
Other answers:
it will coat the inside of the washer and maybe make it stink
maybe make other clothes after stink too or stain them
it is not worth it
a very dirty rag is not worth the cost in hot water, detergent, electricity, and wear and tear on the washer that it takes to clean it.
if you still want to clean it, hand wash it in a bucket outside

no! no! no! only by hand
Just dump it, you said it was a rag.
In addition, you will probably leave a residue in your washer drum that will transfer to future loads. Particularly rags with shoe polish which is wax based can leave a film build-up on the inside of the washer which will rub off on clothing in the next load. I think I would rather dispose of the rags than risk ruining clothing.
