Window plastics cleaner (Solvent cleaner)
This is a great product if you have really bad stains on your window frames, fascias and anything plastic.
I use it all the time after fitting new windows and doors and it gets rid of those glues and stickers that come plastered over new windows and doors when first purchased.
Very strong stuff so wear all the correct PPE and also best to do it in well ventilated areas as it smells really strong and will make you dizzy if exposed to it in confined spaces
Glass cleaner
While on the subject of windows I always use a decent glass cleaner. Its amazing at getting the glass clean and all the marks off.
One of my first jobs as a trainee was to clean all the windows after they had been fitted and what I use to do was clean all the frames with the solvent cleaner then with the same handful of tissue paper spray the window down give is a good wipe down, then get a clean piece of roll and buff it up and it would come up sparkling.
Use some sort of heavy duty roll (as shown below) to use with these products for best results.
