Best Value Glass offers a 10 year applied glass protection option on all of our shower enclosures. This product makes cleaning effortless and protects the glass against harsh water spots. Best Value Glass warranties this product for 10 years, so if at anytime within the 10 year warranty period the glass protection is no longer effective we will re-apply the product at no charge. We include a complimentary bottle of cleaner with every application, and highly recommend using this cleaner on the glass to yield the best results.
