Yearly cleaning of your UPVC gutters will ensure the water filtering off your roof during rainstorms goes into the downspout and routes away from your home. UPVC is a durable plastic and resembles vinyl siding, so you must take precautions when cleaning the gutters. When you are on the ladder cleaning your gutters, it's a good time to clean your soffits since you are already up there.
Place a tarp under the area where you plant to start cleaning the UPVC gutters and weight it down with a few rocks or stakes. Start at the farthest point away from the downspout.
Position a ladder by the gutters. Do not use a ladder that will lean against the UPVC gutters as the weight of your body on the ladder might crush or disfigure the gutters.
Climb onto the roof or stand high enough on the ladder that you can see inside the gutter. Scoop as much of the large debris as you can from the gutter with a garden spade or small shovel. Dump the debris onto the tarp.
Flush the gutters with pressurised water from the garden hose.
Rinse off the outside of the gutters with the garden hose and scrub them lightly with a nylon-bristle brush. Use cleaners designed for vinyl siding if the gutters are stained.
Position a ladder in a manner that you can reach the soffit but the ladder does not rest on the soffit. Resting the ladder on the soffit could damage it.
Fill a bucket with warm water and a mild detergent.
Scrub the surface of the soffit with the solution and a nylon-bristle brush.
Hose the soffit off with a garden hose.
Repeat the cleaning process until the dirt is removed.
