Frequently Asked Questions
As described in the answer to How long do DFI protective coatings last?, maintenance and care vary substantially according to the type of application the abrasion to which the treated material is exposed. Abrasion means any mechanical or non-mechanical force affecting the treated product.
In the vast majority of applications, if a few spots appear, they can be removed simply with cool clear water and a soft cloth or nylon body puff. Just wet the surface and use the cloth or puff to rub the surface in a circular motion. You should feel the places that are “sticky” going back to slick again. Then rinse or spray the surface with more cool, clean water. Wipe dry or let drain and pat dry any remaining droplets.
If you’ve failed to do this basic maintenance, all is not lost! See the answer to What if I haven’t done the basic maintenance?
If you have questions about a specific application, please fill out the contact form on the right or contact your DFI Reseller for the specific maintenance recommendations.
After removing the stains and assuring good ventilation in the area, apply DFI Revitalizer to the previously stained area according to the directions. This will bring the water and oil repellency back to “like-new” performance.
Warning: Using too much pressure with DFI’s Restoration Powder can damage the DFI coating. So please be careful.
You can find all these items in DFI’s handy starter Express Care Kit and larger Consumer Maintenance Kit.
BASIC CLEAN is highly concentrated biodegradable cleaning system for windows, mirrors and shower doors. BASIC CLEAN provides excellent slip and increased wetting but will not cause bleeding or allow squeegee chatter. There is no need for additional wetting agents.
The difference between these coatings is durability and performance, ranked from top to bottom, with the top being best. While each will last years, depending upon the application (see How long do DFI protective coatings last? below), our better coatings will perform better over that time and will require less maintenance. By perform, we mean impart to the surface all of the benefits you love from our coatings, including water and oil repellency, stain resistance, ease of cleaning, impact and scratch resistance, increased brilliance, and a host of other benefits. As such, each product has a different warranty. If you’d like a more in-depth analysis of the differences, you can view a detailed comparison of these coatings here.
For example, a treated automobile windshield in a snowy environment (where salt and sand are spread on the roads and then kicked up onto the windshield) will require a higher level of maintenance and care than a treated exterior of a building in a mild climate. And both will require much less maintenance and care and be beautiful longer than an untreated equivalent!
The great news is that all DFI protective coatings can perform forever with the proper maintenance and care. While your coating will perform as guaranteed in its respective warranty, the as-needed use of DFI’s Revitalizer can extend the life of your coating and the surface it protects literally forever. Please keep in mind that Revitalizer is not necessary in order to satisfy the basic maintenance requirement of any of our warranties, but if you want your coating to last and last, it is a great option to have.
If you are applying DFI’s protective coatings to existing glass, we recommend that you thoroughly clean and dry completely the glass to be treated. A small amount of DFI’s Glass Rescue™ or Restoration Powder and water is ideal for this but other glass cleaners are acceptable. A non-abrasive nylon scrubber will also help remove unseen contaminants.
If you’d like to have your home or building protected, please fill out our Home or Building contact form and we’ll connect you with an Authorized DFI Applicator in your area.
The resulting coating is an ultra-thin protective layer of optically clear material which makes the surface significantly easier to clean and resistant to weathering. The method is done at nano-scale levels, which is a length scale ranging from approximately 1 to 100 nanometers (1 nanometer is 1 billionth of a meter). For comparison, the thickness of a human hair ranges from 40,000 to 100,000 nanometers.
The bond created in the patented process is a covalent bond. A covalent bond means that the coating actually shares electrons with molecules in the glass itself, thus becoming part of the glass. Covalent bonds are approximately 10 times stronger than hydrogen-bridge bonds, which are commonly used in most other water repellent coatings.

Once applied, DFI Nanotechnology eliminates the need for polluting chemical cleaners and reduces the frequency of cleaning necessary, thus reducing the amount of water wasted to perform that cleaning. Both of these have a profound impact on the environment, reducing the demand on our over-burdened fresh water supplies and saving our rivers, lakes and oceans from polluting run-off.
