Metals have an important place in our daily lives.  But, the fact of the matter is that the world of metals is haunted by a scourge: corrosion. And nothing feels worse than seeing your car turn orange!  So understanding corrosion protection is vital.

Below are some of the considerations that you can make to ensure that your metallic beloveds do not corrode:

Choosing The Right Metal

The simplest method for protecting your metallic belongings from corrosion, is to ensure that they are made up of metals that do not rust.  Why have the hassle of rust protection when you can, simply, choose a metal that does not corrode? Here are a few examples:


Aluminium is a corrosion resistant metal, ideal for places that are sure to be affected by Mother Nature.

Stainless Steel

Stainless steel is an alloy; its corrosion resistance is specific to its composition. Stainless 316 and 304 are, both, known to be corrosion resistant and are used, precisely, for this purpose.

Weathering Steel

It is cheaper than stainless steel but does not offer the same guarantee of resistance to corrosion, as stainless steel does.

Whatever metal you choose, WD-40 Multi-Use-Product can be used to form a protective layer, protect against corrosion and reduce the effects of rust.  WD-40 Specialist Penetrant Spray can also be used to rejuvenate an item which has already rusted.

Design is Important

Here are a few things to keep in mind with regard to the design of metallic objects:

  • Try to avoid designs with cavities and crevices, as much as possible, for they accumulate moisture and are the first to corrode.
  • Ideally, weld joints rather than bolt them.
  • The design should allow for air to circulate, freely. If it doesn’t then it will accumulate moisture, with time.
  • For large, metallic structures, ensure that there is adequate space, between its various parts, for conducting rudimentary, maintenance jobs.

Protecting From the Environment

It is important to keep your metals protected from corrosion by limiting their exposure to moisture as much as possible.  However, if that’s not possible or practical, then consider using WD-40 Multi-Use-Product to provide a protective layer.

The World of Coatings

There are also many different kinds of other coatings that can also be considered if you are looking to protect your metals from corrosion.

  • Consider coating a layer of corrosion resistant metal over the surface of the item, that requires protection. It will serve as a barrier against the environment.
  • Use a solution of sodium hydroxide, potassium nitrate and water to immerse small steel items for protection against corrosion. It gives the object a blue-black coloured appearance (“bluing”) and bear in mind, it’s only a temporary solution.
  • Apply oil based coatings to metals that require protection – ideal for stopping the penetration of oxygen and water.

A quick guide to WD-40:

Extensive laboratory testing has shown that WD-40 not only helps to prevent corrosion but can also take care of it once it has happened.    So, the simplest method of protecting your metallic possessions from corrosion is to spray them, once in a while, with WD-40! Job done.
