What to Look for Before Buying

Before going out and buying any product, like the composite deck cleaner or an adjustable door security bar that you believe to be the best in the market, you need to consider and do some research based on your needs.


You have to check the type of materials that you have, which need maintenance and cleaning. Whether they are of wood, composite decks, or other materials, you must get cleaners based on whether your purchased product will provide you with the solution you have wanted it for.


It is a must that you make sure of the area's size that you need to clean. If you have a sizable deck or a small one, you need to keep these in mind before purchasing the cleaner.

Also, think about the storage life of the cleaning agent that you are choosing to buy. It would be wise for you to make sure that the cleaner's shelf life will last long enough for the number of times you will be using it for your cleaning purpose.


You have to make sure whether you need cleaning or do you have to remove specific stains as well. Some cleaners do not help in restoration. In contrast, some may bring life back to your old weathered-down composite deck. Some are only good for getting rid of the moss, mildews, etc.

Now, you will find some cleaners which come in a liquid form. Some you have to buy as a formula and mix them up at home before it is ready for serving you with your purpose.


There are cleaners which you can spray on top of the area and later wash it off. For others, you may need some other equipment such as a pressure washer. Although there are products for manual use, you may have to scrub them off.


Scrubbing can be a hassle for some, while others may prefer a certain level of perfection that may come with it. Some cleaners can be used with both pressure washers and manually, while others may only be applicable for one and not the other.


While chlorine bleach is usually one of the key ingredients for cleaning up composite decks, you need to make sure that this is included within the cleaner that you are purchasing.

On the label, you may see names like sodium hypochlorite or calcium hypochlorite. They will help you eliminate molds and mildew. Oxalic acid is beneficial for removing iron stains.
