"I have tried many different cleaners from cheap ones to expensive ones. This cleaner is excellent takes off all types of marks including sellotape marks. It also gives the upvc a shine. Spray cleaner on rub it in leave it to dry and then use a cloth to buff its so easy."
"For really good results sponge wash really greasy black areas first, wipe down with cloth to dry. Then apply by spraying polish directly on then with slightly rough wiping cloth being liberal according to area size, and wipe clean with micro fibre cloth with exception of black or brown PVC which could be sun bleached anyway most newish windows doors or gutters in white should come up like new, for really soiled plastic use a more abrasive cream cleaner for PVC for a deeper clean. But very good as a whole."
"I was looking for the solvent uPVC cleaner which I can't find and tried this, ok if the uPVC is new but if its old and covered in grime forget it better off using Flash. Also the spray head was poor, more of the product ran down my arm than sprayed on the the uPVC"
