Best ever Glass polish
A customer of ours went to a hand car wash they put something on the screen rthat wouldmnt come off . Then he put WD40, methylated spirits on it . You could only see it as small deposits on the screen , not necessary smeary. We tried every glass cleaner , plus machine polishing compounds , nothing worked . Tried this with a small machine polisher, amazing results. No wonder its out of stock as I write this review !
