"Exceeded my expectations"
26 January 2016
I've just used this product for the first time, and I'm really impressed. It worked faster than I expected, and got rid of all the caked-on tarry marks I've been trying to shift for years. I didn't have to scrub at the glass, either - the marks just wiped straight off the glass. I've always used liquid ammonia to clean the glass in the past, but this product is far more effective and doesn't have a horrible smell. I would recommend using gloves when using this product, as it contains sodium hydroxide.
