Always review your siding manufacturer’s care and maintenance instructions prior to doing anything to siding to ensure you don’t void your warranty. Understanding what’s in your siding and how it’s made can help you decide which products to use and which to avoid. Vinyl siding is relatively robust and can take most things nature inflicts. However, it can be quite sensitive to things we humans do. Bleaching is an example. Bleach and siding DO NOT mix. Siding is designed to be somewhat flexible to withstand expansion, contraction and impact from hail and other things.

If the surface becomes damaged or brittle, you will have to replace the siding sooner. Brittle siding is no good. The more degradation, the more brittle, the more cracks, the more damage, the more degradation, the sooner you need to replace get the picture. We believe that anything over 5% bleach can cause irreversible damage to many surfaces, not just siding. Avoid bleach unless you are a professional with extensive experience using it.


Siding manufacturers advertise the that vinyl siding is ultra-low maintenance; and it is. Vinyl siding requires less maintenance than most any other siding choice. But, everything requires some maintenance. There is the quick, cheap way, and there's the proper way to maintain and maximize the lifespan of vinyl siding. Diluted bleach solution is often recommended simply because bleach is cheap and readily available. If you want to use a very diluted solution of bleach on your siding it is crucial to email your siding manufacturer for the maximum concentration of bleach you can safely use so you have it in writing and can refer to it when you clean like vinyl siding oxidation. Our experience, however, is that most homeowners do not find the manufacturer’s recommended diluted solution to perform well, so they make a stronger solution, which ultimately causes degradation.

So, if you shouldn’t use bleach what should you use like the vinyl siding oxidations? Well, you do not need some exotic $100.00 per gallon cleaner. Our extensive research has narrowed the field to three economical, effective choices. These recommended products do not contain bleach and should be safe for all vinyl siding types and removing the vinyl siding oxidation.

Effectively removes algae (the ugly green stuff), mold/ mildew, and oxidation (the chalky white stuff). It is water-based, zero VOC, and contains no bleach, so it won’t harm siding or plants. Specifically developed for vinyl siding, it is used by major vinyl siding manufacturers and cleaning professionals. This is what I use (I also happen to be the inventor and manufacturer, so I am a bit biased). In fact, I use it on everything: campers/RVs, sidewalks, outdoor fabrics, etc.

This is a good general cleaner. It works similarly to Dawn, in that it does a nice job of removing dirt, pollen and the occasional bird dropping if caught early. I recommend it over Dawn because I find that it performs better than Dawn for most cleaning jobs.

Why Should You Clean Vinyl Siding Oxidation?

In the US, vinyl siding is the most used type of external covering. Because it is a long-lasting, adaptable, and reasonably priced material that is simple to install and maintain, homeowners adore it. However, with time, your vinyl siding and trim can start to show signs of a white, chalky substance.

What you are observing is oxidation or fading. When the polyvinyl chloride (PVC) material is exposed to air and other natural elements, as well as dirt and grime accumulation, it goes through a natural process.

Vinyl siding oxidation has to have removed. In addition to fading and other visual issues, vinyl siding oxidation can cause your outside cladding to degrade or deteriorate. Your vinyl siding can survive for many years if you give it regular care, which also guarantees that it looks excellent.

Vinyl Siding Contractors: What to Look For


Anyone who has noticed a 1-2 inch line at the place where one board overlaps another on their siding, knows there is a reason it’s there. It’s important to understand the purpose of this overlap if you plan to protect, restore or paint your vinyl siding.

The over simplified explanation is that siding is attached to the house via extra large, elongated holes. The screws or nails are pushed through the holes into the house. Since the holes are large, the siding can expand and contract without popping off your house. Vinyl is different in this way than other building material. Since vinyl siding expands and contracts, a 12-foot board may be an inch or so longer or shorter depending on the current outside temperature. Pretty cool, huh?


All siding begins to weather and fade as soon as it’s installed on your home. In fact, everything fades and weathers when exposed to nature’s elements (even a $350,000 Maybach automobile). That’s why I recommend protecting it within the first five years of installation; to preserve its beauty and significantly slow the natural degradation process. It is an important step in the installation process. If you are a DIY'er, then protect away. It’s simple. If you need to hire someone then you should determine if it’s worth the cost. I believe it is. Now that you know more about vinyl siding and how it is installed, we can explore how to choose a product that will protect and preserve it. There are several things to consider when choosing a product.
