A PVC trellis can make a nice addition to your garden. You can use it to provide plant support or to separate your garden into various sections. It also makes an excellent decorative frame for garden art. PVC has proved to be an extremely versatile material for construction and home décor purposes. It is also one of the easier trellis materials to maintain. A guide is given below to help you keep yours in good condition for longer.

Step 1 – Wash with Plain Water

Use a garden hose to give your trellis a quick clean. Simply hose it down with plenty of water. It helps to get rid of dust and loose debris. You may want to wash your trellis this way once a week.

Step 2 – To Remove Stubborn Dirt

Mix some mild detergent with warm water in a bucket. Use the solution to wash your trellis thoroughly. Scrub with a brush to facilitate effective removal of dirt and debris. It is easier to reach the crevices with an old toothbrush. For an effective job, it is best to tackle one side of the trellis first then proceed to the next. Begin at the top and steadily clean the entire surface area until you get to the bottom.

Step 3 – Rinse

Turn on your water hose and spray the trellis with plenty of water. Work from the top and proceed downwards. You may want to spray water from both sides to ensure that it really gets clean.

Step 4 – Mildew

Mix white vinegar and water in equal parts. Place in a spray bottle and spray onto the affected areas. Allow it to stand for about 10 minutes. Scrub the area with a soft scouring pad. If the mildew doesn’t come off, you’ll need to apply some more vinegar and leave it on for a couple of hours. Should the vinegar fail to rid the trellis of mildew, you may want to try oxygen bleach. Mix 5 parts water with 1 part bleach. Place the solution in a spray bottle for easy application. Spray the mildew and leave it on for about 30 minutes. Once it appears to have cleared, wipe the area with a damp sponge, then wash with warm water and a mild detergent.

Step 5 – Repairs

Once your trellis is clean, you’ll be able to spot the areas in need of repair. It helps if you have a PVC trellis repair kit at home. It will come in handy when you need to restore the appearance of your trellis. Follow the instructions in your repair kit to repair damaged areas.
