Because of the latest legislation on UN numbers and chemicals, carrier companies are now NOT letting me send this product in anything over a 5 litre container but I can send as many as I like in 5 litre containers as long as the UN number is on the box!!! Madness rules as ever in Europe!!! So I have made a special price if you order 4 x 5 Litres to compensate. A fast action spray-on cleaner that will remove everyday grime,insects,and tobacco film,leaving your windows sparkling clean, simply sray on and wipe off, very useful in hand car washes for that sparkling finish, no smears, no tears ammonia free.
