What Are The Stains in Roadway Gutters Left Behind After Pressure Washing

A well established common practice in the world of pressure washing is that most service providers eschew the use of chemicals whenever it is feasible in some way, shape or form. A big part of the reason why that is the case has to do with the fact that water can do much of the cleaning that you are attempting to accomplish at any given point in time, so it doesn’t make a lot of sense to use chemicals when you can help it.

Besides, chemicals are the very thing that makes matters so difficult for pressure washing companies in houston, since suffice it to say that they need to invest in waste management if they ever decide to use chemical based cleaners and the like. However, not using chemicals can sometimes reduce the efficacy of what you are trying to do here. After all, while water is a perfectly suitable cleaning fluid, it usually doesn’t kill things like algae or mold. If you see some stains in roadway gutters that have just been power washed, these stains are made up of microbial growth.

These stains are not all that big of a deal, but they can become bothersome if you don’t nip them in the bud. Algae can grow extremely rapidly if given the right conditions, so you need to take great care to chemically sanitize surfaces if you notice black stains. Sometimes these stains are just the true surface of the material shining through the dirt, in which case you wouldn’t have to do a single thing to remove them because they are not doing anyone any harm all in all.
