How to clean vinyl siding and get rid of mold and mildew

When asking for some piece of advice from experts on how to clean vinyl siding and what type of maintenance it requires, probably, you will hear only good news. Well, vinyl really has an array of advantages, and this type of material is easy to clean. It doesn’t require any processing against insects like in wooden options or applying anti-corrosion spray if installing aluminum panels. That’s one of the reasons why vinyl siding is widely recognized by customers around the globe.

However, like timber or aluminum siding, vinyl cladding also has its drawbacks or, it would be better to say, not its strongest points. The fact is that, due to its properties, siding is susceptible to the accumulation of dirt, lichens, grease, soot, and algae on the surface, which certainly affects its characteristics, and not only aesthetics but also durability.

As a result of the impact of natural factors, vinyl horizontal or vertical siding panels gradually lose their protective layer, so their surface becomes porous. Thus, in such cracks and small holes, the mud together with microorganisms continue to destroy the material integrity. And now, on the once neat and attractive house facade, difficult to wash off pollution appears, especially in those places where the wall gets wet and poorly ventilated. If the siding was damaged, and no cleaning procedure and even pressure washing won’t bring back the exterior beauty, be ready to invest in a home renovations project. But with proper and regular care activities, you still can avoid unpleasant consequences and siding deterioration. Let’s take a high dive into how to prolong the vinyl lifespan.

A lack of sunlight and excessive moisture will promote the worsening of the exterior look. But don’t despair just yet. There are a couple of tips to keep your cladding fresh and tidy.
