Look at how effective ClearShield glass protection is! One half of the bottle has been specially treated with ClearShield while the other has been left untreated. Notice how the mud does not stick to the treated half and looks as good as new, demonstrating ClearShield’s ‘non-stick’, stain-resistant properties. In practice this means glass treated with ClearShield is easier to clean and keep clean – the frequency of cleaning is also reduced by 50% on average- as well as looking like new for longer. ClearShield is manufactured by Ritec International who provide low-maintenance solutions for all kinds of glass applications.
