Product Review: ACF50 Corrosion Block grease

1 of 1

ACF50 Corrosion Block grease, £10 approx

Time used: Two years

What’s good? I am a massive fan of the way ACF50 anti-corrosion spray works to keep a British winter’s destructive power at bay, but this is the first time I have used the grease made by the same people. The grease has been primarily aimed at marine and aircraft use but I have used it on my own bikes and MCN long-term test bikes as well as my bicycles with fantastic results. It works to actively stop any corrosion underway, resists being washed away and can be used as a light lubricant too. Caliper bolts, banjo bolts, exhaust header bolts have all been treated and they remain easy to remove. I also used this grease on the exhaust butterfly valve on my Ducati Multistrada 1200 S Touring over two winters. These valves are a dirt magnet and are notorious for seizing but I had no such problems, although the heat did make the grease melt and frequent reapplication was needed.

What’s not? Not a lot really. Like ACF50 spray it just works. Just beware of unscrupulous online sellers with tempting looking prices as low as £2.45. They are only selling a tiny amount, not the 454g pot that costs around £10.
