You can buy a commercial poultice from any hardware or home improvement store.
If you don’t have distilled water, you can use the same liquid cleaner that came with the poultice.
It may take up to 48 hours for your poultice to completely dry.
If poultices don’t remove the stain, contact a professional stone cleaner to try and clean it.
If you have a limestone table or other surface that isn’t flooring, use a handheld vacuum if available. Some vacuums come equipped with an attachment hose. This will also work for an elevated surface like a kitchen counter.
There are several “dust mops” available that would work efficiently for the limestone.
Take your time and don’t hesitate to spend extra time going over the stain with the rag. Soak the rag as many times as you need to.
Dry your shower after each use to prevent soap scum buildup.
You could use a dust mop on a table or countertop as long as the mop is clean.
You should also have outdoor mats to wipe your feet off before entering your house.
Place hot cooking supplies on protective mats. Similar to the condensation cups, the heat produced off hot plates can stain and damage your surfaces too.
