A product called "Zud" will easily remove the stains. Use according to directions on the package.

Zud may not be available in every supermarket but good hardware stores and Plumbing supply houses usually carry it. It comes in powder and liquid form. The liquid is more convenient.

Zud could be viewed as "the next step up" from "Comet" type cleaners but with the specific use of removing more difficult stains. Other than its scouring effect, the active ingredient is oxalic acid, which is quite mild but rubber gloves are a good idea. Read label for full details. Most of the stain removal effect is achived by letting a "paste" of Zud cover the stains for several minutes or so. Little scouring is actually needed to remove the stains.

The "green stains" are an issue which might be worth following up on to determine the cause in individual situations. Often the cause is water which has a greater acidic ph. This can gradually corrode copper pipes, most noticeably the hot water line. This in turn produces the green stains, which are copper salts from the action of the acid water on the copper pipes.

A web search using. e.g. "green stains in bathtub" will produce plenty of reading on all aspects.
