Fogged RV Window do-it-yourself clearing process

This site  The Web 




We developed a "double pane inner space washing/drying process" that we want to share with others in the fogged window club. Our process will give you clear windows again until you have an opportunity to travel to one of the refurbishing facilities. The photos on this page are our windows. The results are more dramatic than shown.

Eventually a double pane window’s seal system will fail. As the inner space heats up, the inner air expands and is forced out of the compromised seal system. When the inner space air cools and contracts, humidity-laden air is drawn in bringing baggage with it that is deposited on the interior glass surfaces (usually turning into a white cloud look). RV failures seem to be between four and seven years. Five of our Class A double pane windows, including the drivers' side window fogged. Driving safety was compromised by the milky side window. Everywhere we turned we heard the same answer: "you will have to bring the coach to our facility and either replace them or have them dismantled and refurbished." We thought that there must be a way to have clear windows without spending hundreds of dollars. Additionally the trip would involve several days.

Our 14 page Copyrighted process description includes easy to follow step-by-step illustrated instructions about building your system, materials lists including parts numbers, where to purchase suggestions, cautions, tips and on-going assistance via email. What you will be creating is an inexpensive and easy to use portable "inner-space" residue removal and moisture maintenance system. This process will not provide a permanent fix for the majority of users. Mini re-fogging may occur and look like "breath on glass". You can easily remove that moisture and have a clear window again in minutes, even at a camp site. Our manual is updated as we receive tips from users. Recently a South Floridian shared his modifications that were required to clear three large picture windows.

Our washing and drying process is very user friendly. On a handy-person skill level scale of 1.0 to 5.0 with 1.0 being the easiest, this is a 2. If you can use a hand drill or power drill you will have no problem with this rewarding project.
The photos on this page are our windows. The results are more dramatic than shown. . You will NOT be attempting to drill holes in your glass - you should never attempt to drill into tempered glass. Part of the process is to construct a simple low volume vacuum/pressure pump, a liquid transfer pump and a mini suction device from readily available off the shelf household items at stores like Wal-Mart. You will literally be washing and drying the inside of your double pane.

Our process was featured in the FMCA magazine New Products, October 2009.  We are pleased to give you encouragement that a clear window again is possible. We wish that we did not have to charge for this material however getting the word out is surprisingly expensive. We will be available by email to assist you through the process if needed.

Until you do something about your fogged window we suggest that you: 1. Shield your fogged window(s)s from direct sun as much as possible. Don't allow the sun to continue baking the baggage that the moisture drags into your double pane inner space. Irreversible surface corrosion can result.  2. Clean out the window drain holes - you don't want your damaged window seals sitting in pools of water.

Contact us if you have any questions now and anytime after you receive the materials.

You must have access to the fogged double pane window's seal to use our clearing process. We will refer to the seal access as "end piece".

The below image is a sliding double pane glass window unit being treated. The red arrows point to the double pane glass end pieces: A- end piece of the sliding section where you usually see bare seal material (Some brands will enclose the entire glass in metal). B- second end piece of the sliding section (locking end) which will be metal. C - end piece of the fixed section, which will be metal.

If you can access A or B or C of the fogged window, metal or no metal, then our process is applicable. You will not have to remove the window from the coach, unless you choose to do so. If you don't have access to an end piece of the fogged glass such as with a door window then you will have to remove that window unit to use our process.

Note:  Tiffin owner reports that the seals on the double pane windows of his coach contain loose materials that will enter the space between the windows when using our process.  We suggest that Tiffin owners not try our process.
