Cleaning gourds can be a time consuming affair. But from my experience it can be quite easy, the key is to be patient for it work. Let's start with the exterior of the gourd, normally gourds are dirty. This is just mold, and dirt dried up. If you are allergic, you might want to have a mask on when handling, and cleaning gourds. And trust me once you get inside the gourds there will be large and fine particles that you need to be aware of and gourd dust gets everywhere! Make sure to have a mask on for that!
The best way I found to clean gourds is to soak them. Use some large rags in a small amount of bleach and water. And wrap your gourds in them, let them soak for an hour or so and removing the grime will be very easy with a scrubber. Sometimes you get patches on the gourd that are white-yellowish, that is normal. And these areas can be a little more difficult to clean off. So re-soak with wet towels, and re-scrub this area with a brillo pad, Stainless steel, or a pot scrubber. This should remove any dirt from your gourd, and get you ready to start cleaning the inside of the gourd!
