One piece of advice for homeowners is to clean the surface of their composite decking immediately they notice stains on it. When homeowners clean their wood-plastic composite decking right away, they will prevent the stain from permanently sticking to the decking surface. So, we have come up with advice on the different composite decking stains and how homeowners can remove them. 

How Do I Remove Stains from Composite Decking?

Cooking Oil Stain

The purpose of installing composite decking is to have outdoor activities on it. One great outdoor activity homeowners can carry out on their plastic wood decking is having a barbecue with friends. Barbecue means cooking meat on a grill until the meat is done. In the process of cooking the meat, oil can spill on the composite decking. Note that plastic wood decking is strong enough to hold a barbecue grill.

 Homeowners can safely add a ready-made barbecue grill on one corner of their plastic wood decking and use it to grill meat when partying with their folks. When oil spills on the surface of wood-plastic composite decking, it will remain on top. Luckily, the newer generation of composite wood decking has a protective shell that prevents stains like oil from infiltrating the boards and staining them permanently. But you still have to remove stains from your plastic wood decking surface. 

Although the stain will not go deep into the boards, it will distort the beautiful appearance of the decking. Homeowners will need warm water, soap and a soft brush to remove cooking oil spills from their composite decking top. Mix the warm water with the soap and apply the solution to the cooking oil. Then, with less force, you should scrub your composite decking surface till the oil is gone. After, use your water hose to rinse your composite decking top. 

Engine Oil and Paint Spill

Aside from cooking oil, other stains that can affect composite decking are engine oil and paint spills. While the former is a little easier to remove, the latter, if left unattended to, is difficult to remove. If you accidentally spill engine oil on your composite decking surface, you should prepare a mixture of warm soapy water. Since the engine oil will not enter the composite boards, scrubbing is easier than wood. Pour the warm water solution on the engine oil stain and scrub your plastic wood decking surface.

 Exert yourself and scrub the plastic wood decking until you have removed the engine oil stain. Removing grease from the top of your plastic wood decking is similar to engine oil. If paint spills on your composite decking when renovating a part of your building, you should immediately clean it with a cloth. There will still be some trace of paint on your plastic wood decking. To completely remove the paint, scrub the top of your wood-plastic composite with soapy water and your brush and ensure that you scrub off any paint film that is on the surface of the decking.
