About HydroSilex

You may feel like HydroSilex is a bit pricey, but you will find out that HydroSilex is less expensive than your traditional products (per application). On average a 32oz bottle of HydroSilex Recharge will give you 7-8 applications per bottle on a mid-size car; on average £7 an application.

HydroSilex is manufactured in Holland with the backing of over 25 years in the automotive care industry. HydroSilex is an easy application with long lasting protective properties, that make caring for your car or boat easy. We offer high quality, accessible products that can be delivered anywhere and used by anyone.

HydroSilex Recharge can be used on virtually any surface. It can be applied to bare metal, stainless steel, aluminum, glass, chrome, plastic, wood, fiberglass, stone, marble, tiles, upholstery, leather, automotive paint, gel coats and more. You can use HydroSilex products on anything smooth; cars, boats, motorcycles, RV’s, planes, backsplashes, mirrors and throughout your home.

Yes, you can use HydroSilex Recharge or Marine on matte, denim or flat finishes. HydroSilex Recharge & Marine only enhances the material you apply it to, so flats stay flat as intended, gloss surfaces become shinier. It will bring back the original colors of material whether it is plastic, vinyl, leather, rubber and more. Shiny surfaces will pop especially on dark colors, metallic paints, higher luster surfaces like chrome and more. You can also use on powder-coated surfaces. Make sure you buff in immediately with a microfiber towel and follow through with a second buff with a dry, clean microfiber towel.

While HydroSilex Recharge is known for its ability to quickly and easily clean any vehicle, HydroSilex Recharge is safe to use on household surfaces as well. We have not been FDA tested to be used on food prepping surfaces. It looks amazing on stainless steel, cabinets, back splashes, glass, mirrors, etc. as grease will wipe off easily, finger prints won’t stick, it’s not flammable and it will bring out the natural look of the materials you coat. We do however recommend that you use Marine vs. Recharge in your home.

HydroSilex Recharge creates an extremely slick surface which serves as a repellent from environmental contaminants, while providing UV protection against fading. HydroSilex Recharge won’t fully repel dust, road grime, bug or bird residues, pollen, etc. but it makes cleaning them off easier afterwards.

Yes, HydroSilex can freeze. You want to make sure you store your products in a climate-controlled environment to prevent freezing.

HydroSilex is environmentally friendly and non-toxic. They contain no harsh acids or heavy solvents and are eco-friendly for rinsing in drains.

Yes, Recharge is safe to use in auto body shops. Our product is a Silica Dioxide based product not Silicon based.

Yes, HydroSilex Recharge and Marine can be applied to a surface that is professionally ceramic coated and used as a maintenance product to help maintain the coating.

We prefer to offer our products directly to the consumer. Please be advised if you buy from an unauthorized reseller or third-party marketplaces, we do not accept any returns or refunds. We ship directly from our warehouse in Holland.

HydroSilex Recharge can last from 6-8 months but will last indefinitely longer if used routinely as it was designed. Apply 2-3 layers of Recharge (waiting 5-7 days between each application) for maximum results. The product is designed to be layered, so the more often it is used, the longer the durability and effect.

HydroSilex Recharge is not flammable. You can use it on any surface from grills, engines, stoves, etc.

Yes, you can. We recommend that you use Marine on your carpets, carseats, leather, etc. Marine is a higher concentration and will give better results on these surfaces.

HydroSilex Recharge was designed to be continually used for maintenance and to have the ability to be layered. Which means that the product can be applied and will add an additional layer to the existing Recharge layer on the surface with each use. It is recommended to allow 5-7 days between applying each layer. You can reapply however often you feel the need making sure you wait the 5-7 days between each application.

Recharge is engineered to be used as both a maintenance coating for traditional coated surfaces or as a stand-alone protection. It works with any professional coating brand to help maintain gloss, self-cleaning, UV protection and the slick surface feel. As a stand-alone, it also provides the same features.

HydroSilex Recharge is a ceramic-based coating, it is not designed to resist scratches like a conventional glass coating.

By design, HydroSilex Recharge gives instant hydrophobic effect upon contact. Although it is engineered to be applied dry, the surface can be exposed to water immediately. Yes, HydroSilex Recharge creates a slick surface that is extremely hydrophobic and thus creating a self-cleaning surface that requires less maintenance than a normal surface. 

HydroSilex Marine is a higher concentration for a more porous surface such as a gelcoat.

Yes, you will want to remove any wax or other contaminants before applying HydroSilex Recharge. We recommend that you use HydroSilex Rewind to remove any previous wax, grease or contaminants.

HydroSilex Marine can last from 6 to 8 months; but will last indefinitely longer if used routinely as it was designed. You will also want to start with a good base of 2-3 layers waiting 5-7 days between each layer to make sure all pores of the surface are covered.

Yes, HydroSilex provides protection against oxidation and fading from UV exposure. It will not correct previous oxidation or fading but it will help prevent further oxidation or fading. We recommend having any oxidation or fading corrected before applying Recharge or Marine.

Application / Use

We recommend that you apply 2 layers if this is your initial or first time applying (waiting 5-7 days between each application) for a strong base coat if you do not have a professional ceramic coating. After your initial application you can reapply at your leisure. However, we recommend reapplying a layer at least every 3-4 months for continuous protection and easy cleaning. You may find that you need to reapply to your windshield every 1-2 months due to the abrasion from the windshield wipers. HydroSilex Recharge is designed to be layered, the more the better.  

No, you do not need to use Rewind before each application, but we recommend using Rewind to ensure a good covalent bond/clean substrate before your initial application to remove any previous wax, grease or other contaminants. Rewind is also a great prepping product. You will want to wash with Silica Soap after using Rewind, then dry the surface before applying Recharge.

You will use 1oz of Silica Soap per wash bucket or foam cannon and top with warm water. Wash car as normal with a foam cannon or by hand using a sponge and dry the surface with a clean microfiber towel.

HydroSilex works great on all paint colors, metallics and more!

HydroSilex does not remove water spots. If your surfaces have water spots or paint imperfections, HydroSilex Recharge will enhance these imperfections and show them immediately. We recommend removing the water spots and correcting the paint imperfections.

1) Spray an even mist onto a clean, dry, cool surface. One small panel/section at a time.

2) Immediately buff with a clean microfiber towel in a waving motion.

3) Follow up with a second light buff using another clean microfiber towel in a waving motion.

Yes, we recommend that you prep the surface before applying HydroSilex. Depending on the type of surface, the prep work will vary. If you are applying Recharge to a surface that had wax or other coatings on you will want to prep with Rewind & Silica Soap; then dry and apply Recharge. For other surfaces you will want to make sure they are free and clean from any contaminants and then apply Recharge or Marine to the surface.

You can use HydroSilex Rewind to remove Recharge.

We recommend that you wait 14 days if it was baked or 30 days if it was air dried.

Yes, HydroSilex is a multi-surface friendly product that can be used on almost any surface, including vinyl wraps and clear bras; giving you the benefits you have seen in our videos. HydroSilex Recharge is great for use on paint protection film as those products do not have built in protection against UV exposure. It will help keep those surfaces easy to clean by creating a slick barrier, without the common build up by the waxes and sealants on the edges of the film. 

No, you do not want to apply Recharge over wax. Recharge is designed as a replacement for traditional waxes and sealants. Our recommendation is to apply Recharge as the sole product and not in conjunction with a wax or sealant. Those products will not add any additional benefits and can interfere with the features of Recharge. For automotive paints, if the vehicle requires claying or Rewind, removing the contaminants will help create an even slicker surface when using Recharge.

1. Apply to a clean, cool, dry surface, clear from any wax or sealant residue. 

2. Apply to one panel/section at a time. Always use a waving motion when buffing. 

3. Do not allow Recharge or Marine to self-dry on the surface. 

4. You can apply Recharge to all surfaces on the vehicle; paint, windows, tires, headlights etc.

5. You can apply Marine to all exterior surfaces of the vessel; paint, gel coat, windshield, vinyl, brightwork etc. 

6. Do not spray product excessively onto surface, e.g. 3-6oz Recharge per standard sized car. 32 oz Marine will do approximately 3 coats per 20-25’ vessel.

7. Clean wipers from any overspray. 

8. Always use clean, dry microfiber towels only!

9. Do not apply in direct sunlight, strong winds or extreme heat.

10. Store product in a climate-controlled environment.

11. Apply 2-3 layers of Recharge (waiting 5-7 days between each application) for maximum results.

You lightly spray the surface with Marine, and you can gently rub in with a gloved hand to make sure that all the fibers and surface is covered but you do not want to rub around much. Do not over spray, start with less and build up. Allow the surface to dry completely before using.

We recommend that you use HydroSilex Marine in your home for your cabinets, appliances, shower stalls, outdoor furniture, etc. as the product is more concentrated than Recharge and will give better and longer lasting results.
