Last Updated on December 2, 2021 by Chris Ross

Chainsaw is among the popular household items. And It is in use more than often, so its maintenance is the deciding factor. But It is vulnerable to unwanted debris that leads it to rust. So, clean it after every use. Mind it that cleaning it with random fluid might further deteriorate it.

So, you have found out that your chain saw is clogged with dirt plant remnants, sap, and resin that if not clean, it will cause it to rust and inhibit the functionality of the Chainsaw.

But you don’t have chainsaw cleaner and may look for that, “Can I use WD-40 to clean the Chainsaw?”

Then the answer is YES. If you need a quick fix and you’re without a chain saw cleaner then you can definitely use WD-40.


How can we maintain chainsaws?

Cleaning a chainsaw is a long and tedious process. What would be the cost if we came to know that our method just ruined it. To avoid that situation, we should have proper knowledge of what we clean chainsaws. In other words, we need to have answers to the following questions.

Use water To Clean Chainsaw?

Do not wash the part of the chain covered with oil in water. Go for a brake cleaner as it effectively eliminates the dust with oil away. Secondly, water promotes the rusting process in different parts of the chainsaw.

And if chainsaws parts are not allowed to dry properly, it might be impossible to take them out once fitted. For a slightly dirty bar, use soap and water to clean the chainsaw.

But if it is heavily stained, then degreaser solvent would be a better choice to clean away the gunk. And to clean the guide bar, either use a groove tool or a putty knife. 

What is WD40 Degreaser?

The chainsaw is prone to get heavily soiled, so degreaser is the only remaining option. Water displacement 40 (WD40) is a degreaser. It contains an anti-corrosion agent with ingredients for water displacement, penetration, and soil removal. It is the most widely used degreaser. But the question is, can it be used to clean chainsaws?

Can WD40 Be Used to Clean Chainsaw?

Upside of WD40

To avoid friction, and rust lubricate the chain with WD40. Apart from this, it does not allow the formation of future contaminants that are vulnerable after every use. That reduces the wear and tear of the chain. Lastly, it is durable and stays on the chain to allow a smooth use of a chainsaw and avoid overheating.

Downside of WD40

 Just like any other lubricant, WD40 also has downsides. Some users recommend using it only when the chain starts soaking water, to blow away, and then put some renowned lube. It shouldn’t be lube until there is a lump of dirt or, it will cause adverse effects.

While the other says that to avoid spraying it with other lube or cracks will start appearing in the chain. Secondly, never spray it around the seal of the bearing, which can remove grease and leave it to dry.

Alternative of WD40

 Make a lube- ten parts of paint thinner having a low odour, and four portions of Bar oil. Or go for the biodegradable and nontoxic degreaser together with the use of a brush to remove heavy dirt.

You can also spray the blade with WD-40 that helps protect it from rusting.

Step 3: Lubricate and Reassemble the Chainsaw
