HG window cleaner is a super concentrated product which cleans and degreases absolutely streakless but which does not contain ammonia or methylated spirits. No wonder this product is used by professional window cleaners. HG window cleaner exceeds all professional requirements, because the product is pH neutral, so that it will not harm paint, varnish or plastics and is also very gentle for your skin. HG window cleaner is very economical to use, because one 500 ml bottle is sufficient for at least 35 window washes.
