WCF 4 is a spray-on, lubricating and dewatering fluid which will help to release rusted and seized parts, whilst offering corrosion protection indoors for up to 6 months.

As well as lubricating and freeing up seized parts, WCF 4 is also a dewatering or ‘water repellant’ fluid, this means that once you’ve used it and allowed the area to dry, you can be sure that there is no water left behind to cause further rusting.  WCF 4 can also be used to dry out ignition systems to prevent shorting., although care should be taken around electrical components and do not spray on to circuits where sparking is likely to occur.

Suitable for use on rusted and seized nuts and bolts, painted surfaces, rubber, plastics and most metals, this is a great product to have around whether in a workshop or at home. Simply spray on to the area or component and leave for a few minutes to penetrate, then try some gentle manipulation of the seized part, stubborn areas may require a second application.


You may find other applications for this handy product such as silencing squeaky hinges and lubricating door locks to help free up the mechanism.


It can be purchased as individual cans or if you buy a dozen, you’ll get 12 cans for the price of 10.
