Accelerated testing by independent agencies in both North America and Europe has shown that HMI’s C.10 Glass Protection with Microban® will far outlast any other treatment on a single application, surpassing 10 years of easy-clean properties without a requirement of a special wash, top-up product, or revitalizer. HMI C.10 with Microban® is also independently tested for durability and the treatment should continue to perform well after the 10-year warranty period.

What are the basic maintenance recommendations?

After each use simply drying with a squeegee or towel will keep the glass clean for a long period, and make it difficult for mineral spots to form. The glass needs to be cleaned regularly using a damp microfiber cloth and a mild detergent (such as Dawn or 7th Generation) to break down soaps, oils, and conditioners, a quick clean will prevent a build-up forming on top of the glass protection. General glass cleaners are also suitable, however most of these are finishing agents rather than cleaners, and are an added expense that is not required.

What are the hard water maintenance recommendations?

In hard water areas, or areas where water drops dry and leave a noticeable dust mark, a build-up of minerals may occur on the protective treatment. While these may not be removed easily with the mild detergent, mild acids will often remove the marks quickly. As needed, white vinegar should be used to wipe down the glass with a soft sponge. The vinegar may be diluted, however dilution reduces the effectiveness. Squeegeeing or wiping down after each use will stop these water drops drying into dust marks. In regions with high Silica in the water, the manufacturer recommends using a squeegee after EVERY use. Note: Visible streaking or swirling patterns may appear on the glass when the glass is steamed up. This is a normal occurrence and does not affect the performance of the surface protection. It isn’t visible when the shower is dry and not in use.

What are the approved cleaning products?

There are no specific products that you are required to purchase in order to keep your glass clean. All you should need for beyond 10 years is a squeegee, a mild liquid dish soap, and white vinegar. There is no solvent that will damage HMI C.10 with Microban®, products such as Windex, SprayWay, Scrubbing Bubbles, 7th Generation, and Method are acceptable, however are not necessary.

What are the prohibited cleaning products?

Do not use any rough, gritty or abrasive cleaners. The HMI C.10 Glass Protection with Microban® can also be affected by cleaning products containing very strong alkalis and by modern mold removing agents containing a combination of bleach and sodium hydroxide.

Avoid harsh or chemical cleaners, with correct maintenance these are never required.

Avoid abrasives or polishes, including water spot removers and even toothpaste.
