Scale Buster is a cleaner for use on water deposits and stains which cannot be removed with normal shampoo washing. When rain water is left on a painted surface, the moisture evaporates leaving behind the calcium and dust contained in the droplet. This becomes a spot in the shape of the repelled droplet. Water deposits can also accumulate in places where moisture forms residues, such as gaps in molding. Unlike compounds, it does not require polishing. Simply wipe it off to remove.
To remove water deposits from tight places, take some cleaner on a cotton swab and rub it on the area.
For painted surfaces, put some cleaner on a cloth or sponge and use it to wash and rinse the area.

*This fluid is acidic. Please wear gloves when working with the fluid and do not leave it after application.
*The product may damage a painted surface depending on the conditions, so be sure to test it in a less visible area before use.
