Full Blast Pressure Washing Guarantees Streak Free Windows

Look at this comparison of  the difference Full Blast Pressure Washing can make for your dirty windows. On the left side is a before photo of one of the dirtiest windows I have ever seen. There was actually algae growing ON the window pane, and all over the vinyl trim and sill. To the right is the after picture which shows that not only is ALL of the algae gone, there is also no ugly residue, film, or streaking left on the windows. After a thorough low-pressure house wash, these windows were not streaky; just squeaky clean!


Many companies have repeated issues with window streaking or film \ residue build up. This can be caused by many factors, all of which we, at Full Blast Pressure Washing, work hard to avoid. The two biggest culprits in streaking and film build up are (1) use of bad chemicals or a bad chemical ratio and (2) failure to properly rinse after chemical application — or failure to rinse at all! — lets look at these two issues and how we avoid these problems at Full Blast Pressure Washing:

1. Bad Chemicals or Bad Chemical Ratio – The active cleaning ingredient in ALL effective house wash mixes in the North Carolina area is bleach (technically, 12.5% sodium hypochlorite). This is *necessary* in our region in order to denature and remove algae and mildew from siding. There is nothing wrong with using bleach in appropriate dillutions, but the issue is that bleach crystals tend to get left behind after the water it is sprayed up with has rolled off or evaporated. This is what causes the streaks and film to appear after the guy who caused it has left — with your money in his pocket! To compensate for this property of bleach, a good pressure washing company will find an appropriate rinse aid and surfactant (soap) to counteract the “clingy” nature of bleach particles.

The problem however then becomes, *which* chemicals do you add to your mix? How many will you need, and how much of each of them? Many companies skip this whole process, just using bleach alone and leaving your windows streaky. Some go too far, using as many as 4 or 5 separate ingredients in their house wash mix. This can cause all sorts of complications. Are these even the right mix of ingredients? Are the ratios correct? Are they SURE about that?

At Full Blast Pressure Washing we have spent a lot of time testing and researching available products, and have actually found a combination product that serves us both as a true rinse aid (meaning it interferes at the molecular level with the bonding of particles to surfaces) and as a surfactant (meaning it actually helps to lift dirt out of and off of surfaces).

The greatest thing about this product is that it is 100% ALL NATURAL, PLANT-BASED, AND BIODEGRADEABLE.  We love being able to provide top quality results for our customers, while still respecting our planet.  However, even with the best chemicals, and best ratios, you still have to do a PROPER RINSE.

2. Poor Rinsing – If the issue of chemicals and ratios was a complicated one, this one is very simple, really. RINSE RINSE RINSE. Though I like to think we actually end up needing to rinse less than other companies, because we have a very well balanced chemical solution that comes out at much lower concentrations than our competition, we still rinse quite thoroughly.

Unlike some companies that only have the standard set of pressure washing tips (nozzles) that came with their unit, we actually shelled out the extra cash for a non-standard tip that allows us to spray a low pressure hose stream against the house.

The difference here is impressive. On a hot summer day, the competition may swing past the windows in 3 or 4 seconds with a super fine mist. The problem is that it is so hot out that this mist is actually being repelled from the window by thermal currents surrounding the house, and the fine water particles that do make it to the actual glass end up evaporating before they ever have a chance to actually RINSE the window off! I’m not kidding. In the middle of the summer you can actually watch the steam pouring off the windows.

Our solution in situations like this is simple: just switch nozzles. We put on our long range hose nozzle and pour 1-3 gallons of water directly on to the window at low pressure. This doesn’t harm the seals, and it doesn’t intrude in to the siding, it just lands on the windows and cascades gently down to the ground. By doing this we are assured of a far superior pressure washing result. No streaking or film, and no debris left sitting in your sills.

One final comment: sometimes we do make mistakes. Everyone does. But the question is, will it be rectified? At Full Blast Pressure Washing Raleigh we GUARANTEE CUSTOMER SATISFACTION. If you aren’t satisfied — say you notice one window that we missed — we will come back and fix the problem. We guarantee you will be happy or we will give you your money back! It’s just that easy.

    This is a fantastic post by Full Blast Pressure Washing. Very valuable tips and information have been given here. Pressure washing is a superb cleaning technique for rough surfaces such as garage floor, pavement, walls, fences or cars. Power washers are efficient cleaning tools because they use air pressure and water to eliminate deep down surface dirt. The main value of power washers is that they save time and are cost-effective. Thanks for sharing this valuable post with us.

    Right now it seems like BlogEngine is the best blogging platform out there right now. (from what I’ve read) Is that what you are using on your power washing blog?

      This is a premium theme from themeforest.net … the theme is called “ecobiz”. We have made a few very minor changes to the theme coding, but it is generally how it looks. You can find other examples of it in use on his page. Good luck. :D
