If you have recently purchased a street sweeper, then you have the very important job of keeping the roads clean and clear in your city. Dirt, garbage, and even oily residue on the road is picked up with your street sweeping machine. The brushes on the bottom of your vehicle are essential in releasing the debris from the road. This means that you need to maintain them properly by following the cleaning and protection tips below.
Clean the Brushes
One of the easiest ways to maintain the brushes on the bottom of your street sweeper is to clean them after you clear roads. Most street sweepers are fitted with polypropylene brushes. Polypropylene is a thermoplastic polymer that is strong, flexible, and extremely durable. The thin plastic pieces of your brushes can become caked with debris though, and this can cause bends and breaks across the bristles. To prevent this from happening, clean the bristles as thoroughly as possible.
Begin the cleaning process by using a pressure washer to release as much dirt and debris as you can from the bristles. Consider using a light or medium duty washer that releases between 1,500 and 2,800 pounds of pressure per square inch. This will help to minimize bristle breaks. Inspect the bristles for signs of oil and grease and spread baking soda across the brush to soak up oily residue. Mix about one half a cup of dish detergent in a five gallon bucket of water and use a sponge to apply the soapy fluid to the sweeper bristles. Use your pressure washer again to release the baking soda, soap, and debris.
Protect the Bristles
Polypropylene does not need a protective coating or material to keep the sweeper bristles in good condition. The plastic brushes do need to be kept out of direct sunlight though. UV rays cause the bristles to degrade over time, and damage will be seen as small cracks and lines across the plastic materials. As exposure increases, the cracks deepen and the bristles will start to break off. Make sure to store your street sweeper in a garage to reduce sun exposure.
Stainless Steel Bristles
Clean the Brushes
If your street sweeper is made to clean the gutters that line the streets in your city, then you likely have stainless steel brushes. Stainless steel bristles are covered with a chromium film that helps to keep the brushes from rusting and tarnishing. This film needs to be kept intact so your gutter brushes do not leave oxidation residue on the streets. You can use a pressure washer and dish detergent to clear away the majority of debris.
If you see stains forming on the steel bristles, then you will need a slightly stronger cleaner to release them. Ammonia can be used as a cleaner. Fill up about half of a large spray bottle with ammonia and fill the rest with water. Add two squirts of dish detergent and spray the sweeper brush. Allow the cleaner to sit for about 15 minutes and use your pressure washer to clear the stains and cleaner away.
Protect the Bristles
Once you have cleaned the stainless steel brushes, allow them to air dry completely. This will help to prevent oxidation. You can also minimize rust formations by applying a protective coating on the stainless steel to keep moisture from reaching the chromium layer on the metal. Olive oil can offer this protection, so use a cloth to spread a generous amount of it on the steel bristles. Use a clean cloth to remove the majority of the oil afterwards. Buff the bristles until they no longer feel greasy.
