Roor Anti-Lime Solution is great for combating lime scale on your glass bong. Because of some tap water being so hard, lime-deposits will gather with time on the surface of the glass. This results in the glass becoming dull and dirty.
We highly recommend using the Roor Anti-lime Solution periodically – good results will only be achieved if the pipe is cleaned before use.
Also be aware that the Roor Anti-Lime Solution is a product of the original Roor.de from Germany. Their solution works brilliantly with their bongs, but has been known to damage the non-ceramic logos of inferior glass bongs.
