How to Remove Barnacles From an Old Bottle

Barnacles are ocean crustaceans that live in shallow waters. As larvae, they attach themselves to any hard surface and remain affixed for the rest of their lives. Barnacles secrete a special kind of glue that makes them a chore to remove from any surface. Boating enthusiasts frequently face the task of removing barnacles from the hull of boats, and multiple products have been specifically engineered for this purpose. However, removing barnacles from more delicate surfaces, such as bottles, requires a slightly different approach.

Things You'll Need

Vinegar
Heavy gloves
Protective eyewear
Scissors or utility knife
Plastic paint scraper or putty knife
Stainless steel mesh glove
Steel wool
Lime cleaner

Instructions

Scraping
- 1
  Soak the bottle in vinegar for a few hours, or as long as overnight. This natural solution may help soften the barnacles, allowing for easier removal.
- 2
  Chip away the larger parts of the barnacles with the plastic paint scraper or putty knife. Work slowly to avoid scratching the surface of the bottle, and angle the scraper to get underneath the surface of the barnacles. Rounding the edge of the paint scraper prior to use will help you avoid scratching the surface. This can be accomplished by trimming the edges with scissors or a utility knife.
- 3
  Remove the remaining barnacle pieces with the stainless steel glove. Again, work slowly, increasing pressure only as needed. Steel wool can also be used, but use the lowest grade available.
- 4
  Clean the surface of the glass with lime cleaner to remove any remaining residue. Another soak in vinegar should also do the trick.
