At some point while eating out in Sevilla you will inevitably spill olive oil down your shirt or on your trousers. Don’t panic. Simply ask the barman for “el espray”, apply it to the stained area from an arm’s length distance, let it dry completely (it will turn white) and then ask for the “cepillo” to brush off the dried powder. And… stain gone! Every bar has this but visitors don’t know about it.
Here is Mallory & Emmerson showing us how it’s done on one of my tapas tours. In this case we sprayed in one bar and brushed in the next. Works every time.
