Using extreme caution, it is possible to make a chromic acid cleaning solution at home. The ingredients aren't available at your local supermarket, but you can purchase them online.
Things You Will Need
-
Place a clean, glass liter beaker in a glass pan to prevent damage from accidental spills.
-
Wearing rubber gloves, put 20 g of powdered sodium dichromate into the liter glass beaker.
-
Mix in a small amount of water to form a paste, and stir thoroughly with a glass stirring rod.
-
Continue to stir the mixture while slowly adding 300 ml of concentrated sulfuric acid to the beaker.
-
Carefully pour the solution from the beaker into a glass bottle with a stopper on top.
The Drip Cap
