That's The Way To Do It? NOT!
So you live on a development fitted with uPVC window frames and it is time for your managing agent to clean them?
The managing agent could use hot soapy water a non scratch sponge followed by rinsing off with cold water and to make ther job perfect they can add a car wax to the frames.
Or, you could if you were a Firstport appointed contractor use a high pressure jet wash that is normally used to clean brickwork, blasting the dirt off but in the process compromise the integrity of the frames.
