How can i clean my polycarbonate conservatory roof.
Take care if using a pressure washer on your conservatory.
If you ve missed any spots now is the time to go over them with a small sponge and water.

The pressure washer while it will get the roof clean will also damage the seals of the glass or plastic roof panels.
Many people think that is okay to pressure wash a conservatory roof but it actually isn t.
If you re giving the conservatory a fairly rigorous wash from the outside you might want to use a pressure washer or garden hose to rinse the roof properly.
Use soft bristled brushes and microfibre cloths when cleaning the conservatory roof to avoid scratching the glass or frames.
That s because these tiles are made of granular concrete and the pressure will actually degrade and wear them away significantly.
Once you re satisfied with all of your work then you can rinse off the roof with a pressure washer and some clean water.
The strong jet of water can break the seals of the glass and cause leaks.
It is better to use a garden hose to remove any soap and debris.
If it s glass you can use a pressure washer but watch out for the ridge which may be vented.
