ACF-50 Corrosion Protection For Motorcycles
ACF-50 Corrosion Protection

By now you should of heard about ACF-50 Corrosion Protection and if you haven’t, where have you been hiding? This super duper pink liquid is the best thing you’ll ever put on your bike this winter, so carry on reading to learn more!

What is this pink liquid, called ACF-50 you speak of?

ACF-50 (Anti-Corrosion Formula) was originally designed to protect aircraft from existing and new corrosion, and it has been available to motorcyclists for a while now. Aviation products have to meet rigorously high standards and ACF-50 not only meets these but has been awarded Aviation approvals – MIL-SPEC 81309 types II and III which means it is ‘approved for ferrous and non-ferrous metals, electrical systems and electronic components’.

The US Navy carried out tests using ACF-50 on the jets on their Aircraft Carriers. They found that ACF-50 significantly reduced the corrosion so much more than they had previously experienced they now use ACF-50 all the time!


So how will help your bike? 

Just like it protects jet engines and highly sensitive electrical components, it also does a damn good job protecting your motorcycle from rust and corrosion, especially if you ride during the winter months through all that salt and grime on the roads. It’s even awesome for off road bikes or enduro bikes to protect them and keep them reliable and in good running order.

How does it work?

Unlike other oil based sprays, ACF-50 when applied, forms an ‘Active’ ultra-thin clear film that will kill any existing corrosion cells and will protect your bike against new corrosion forming. On areas such as switches or under the tank and seat, one application will last up to 12 months! Other more exposed areas will need topping up more regularly. ACF-50 has the ability to ‘chemically neutralise road salt’ and water will bead on contact and literally bounce off. Ideal for the bike that is used all year round in all weathers, a superb service spray as ACF-50 is also a lubricant and penetrant (without loosening structural attachments) and if you put your bike away for the winter, applying ACF-50 will ensure that moisture will not be allowed to cause any damage! Untreated moisture will creep into cracks and will not freely evaporate – ACF-50 actively ejects moisture from these areas.

The best, way to describe it, is that ACF-50 is like a protection suit for your motorcycle and the good thing is, it really works. You’ve only got to go on Google and search to see the many bikers that swear by it. Quite frankly, you’d be a fool to ride through winter or muddy puddles without it on your bike.


How do you apply ACF-50 on your motorbike?

This is the fun part. The best and most effective way to coat your motorcycle in ACF-50 would be to first give your bike a thorough clean. Trust me, doing this bit right will make a huge difference, so don’t be tempted to skimp on getting that toothbrush out and into all the nooks and crannies, use your wife’s toothbrush, she won’t mind!

  1. After cleaning the bike thoroughly with a none corrosive cleaner, you need to ensure the bike is bone dry, so use an airline if you have one to blast moisture out of all the hard to reach areas.
  2. Wipe all the surfaces with a lint free cloth
  3. Now cover up your wheels and brakes. This bit is important, you don’t want that, slippery substance on your brakes or tyres. The best way to do this is to use a couple of old bed sheets. Make sure none of the spray can get in through any gaps. Don’t worry parts you do want to cover, like fork legs, you can do this later with a cloth or paint brush.
  4. If you have one, or you want to do this properly, you’ll need a spray gun. One of those electric top fed ones are ideal and don’t cost much. This will make applying the ACF-50 much easier and allows for a fine mist spray to get into all the areas you can’t reach. It also makes drying quicker.
  5. Warm the bottle of ACF-50 up before pouring into the spray bottle, this helps it to spray better through the nozzle on the spray gun creating a fine mist. Which, is exactly what you want.
  6. Depending on which option you purchase, some smaller bottles come with a hand pump bottle, these are OK but the jet produced is more of a direct squirt rather than a mist and it prevents even distribution, so we recommend either an electric spray gun or the hand pump spray. See links at bottom of page.
  7. Spray liberally all over until a glossy finish is produced, not too much, you’re not spray painting here, just coating the surface thoroughly with an even spread.
  8. Leave for a while to dry. Any, areas that, haven’t dried will need to be wiped over with a lint free cloth.
  9. Once you’re done with the spray gun, you can then use a lint free cloth with some ACF-50 applied to it, to wipe any areas previously covered with the sheets. Just be careful not to get any on the brake discs or tyres!
  10. Stand back, admire your hard work and enjoy corrosion free riding for the next 12 months.

A couple of things to note

Don’t be tempted to jet wash the bike, this will blast the ACF-50 off and you don’t want that. If you really can’t cope with having a dirty bike, just use a hose and lightly spray any build up of dirt. You may, have to top up some areas throughout the year, especially those that get subjected to surface spray.

By doing this you insure your bike against corrosion, such as road salt, mud, dirt, pollutants and so on. It also keeps your electrical connectors free of water and prevents breakdowns or other unwanted surprises.

Having used this myself on a 2016 Honda Africa Twin Crf1000l, I can, hand on heart say its amazing. After riding 62,000 miles and having performed this procedure 4 times, my bike looks like brand new when it’s given a full valet. There’s no corrosion anywhere. The trick is to ensure the bike is bone dry before you apply.

Have fun and enjoy.
