Somebody recently joked about me looking so much older than the younger man in some of my YouTube videos from years ago. Well, like Indiana Jones said, "It's not the years; it's the mileage." But with thousands upon thousands of hours spend outside cleaning - and along with the aching back, creaking knees, and throbbing right shoulder - comes the benefit of experience and breadth of view. I've seen things come and go over long enough periods of time to notice trends in the exterior cleaning industry. In this blog I'd like to share an observations regarding one of those trends. First, it's important to realize that the exterior cleaning market on Cape Cod is vastly different than nearly all of the rest of the country, because our roofs and siding materials are vastly different. Most residential construction in the U.S. features siding of vinyl, composite, or mayyyyybe painted wood. Roofs are almost always asphalt/composite. The bare cedar surfaces found so commonly here on roofs and siding are very, very rare in most of the United States. We are a tiny, tiny niche market. Similarly, the exterior cleaning industry on Cape Cod is necessarily different from the exterior cleaning industry elsewhere, where those hard, synthetic or painted surfaces are readily "soft washed" with a chemical solution dominated by sodium hypochlorite (i.e. bleach). While sodium hypo - or "SH" in industry parlance - is a fine and appropriate ingredient for cleaning many hard, non-porous surfaces (vinyl siding, "Hardiboard," tile roofs... I'm looking at you, Florida), SH simply isn't the do-all solution when it comes to cedar... especially the WHITE cedar so prevalent here on Cape Cod. Don't get me wrong: chlorine bleach does has its place in the local cleaning toolbox, but the toolbox necessarily contains many other tools as well. Companies such as Harwich-based Wash Safe set the standard years ago for non-chlorine cedar cleaning products, instead relying heavily on the cleaning power of sodium percarbonate ("hydrogen peroxide")-based cleaning chemicals. These non-bleach cleaning chemicals required different cleaning equipment and processes than the rest of the country was using to clean everything with bleach. Because our local cleaning needs are so unusual and insignificant compared to the nationwide industry as a whole, the ever-increasing number of companies who make fancy trucks and trailers for the exterior cleaning industry have never been motivated to make products designed for our niche ways of cleaning. So, on a national level, the equipment being marketed to the exterior cleaning industry has been nearly entirely designed for those who clean with bleach. For this reason, the experienced cleaners on Cape Cod have long since resorted to designing and building their own custom "cleaning rigs." I did the same. So, for years, one observable trend has been for cleaning equipment to become ever-more tailored to the legions of "Bleach Bandits." Pumps were built to be more and more resistant to SH's corrosive effects; synthetic bleach stain-proof clothing was marketed to cleaners; metered mixing manifolds allowed the fine-tuning of the bleach application. Then, the mixing valves became controllable with a little key FOB from your position on the ladder. Bleach, bleach, bleach. . But change is in the air. Happily, in this one little way at least, the change is a good thing. It seems that us niche wood guys are starting to be heard by the broader exterior cleaning industry. Many chemical vendors have added sodium percarbonate to their lineups, making their own version of "Wash Safe Cedar Wash." Even better, sodium metasilicate (the EPA's preferred replacement for trisodium phosphate, or TSP) has crept into common availability such that even companies in the very heart of bleach country are now offering their own sodium metasilicate-based wood cleaning formulations (looking at you, Southeast Softwash ). Today, the wood-cleaning crowd is being heard by even some cleaning equipment makers. Case in point: yesterday, I met with a young cleaner off-Cape who is adding a fancy, factory-build cleaning trailer to his small cleaning fleet. AND, to my delighted wonder, along with the typical bleach-slinging tools, the trailer included a tank labeled for (gasp) sodium percarbonate! I couldn't have been happier for him or the industry. Including more tools in the tool box, and thereby recognizing that bleach isn't the right tool for every cleaning situation, is a step in a better direction.
