The maintenance of the brake system is crucial to ensure safe driving. A common question that arises in the automotive community is whether WD40, known for its versatility in various maintenance applications, is suitable for cleaning a car’s brakes.
Below, we break down this topic to clear up any doubts.
What is WD40?
WD40 is a multipurpose oil that acts as a degreaser, lubricant, and rust protector. Due to its effectiveness in various tasks, it is not uncommon for someone to wonder if it also works to remove dirt from brake discs and calipers.
This product is one of the most used when it comes to repairing almost anything in a car. In fact, we always recommend carrying a small can of this product in the trunk, as it can get us out of a tight spot in a matter of seconds.
Using WD40 for brake cleaning. Is it recommended?
The short answer is no, WD40 is not recommended for cleaning a car’s brakes. Although this product has numerous applications, brake cleaning is not one of them.
Reasons to avoid it
WD40 acts as a lubricant, which is precisely the opposite of what is desired in a brake system. A lubricant on the brakes could seriously compromise the vehicle’s stopping ability, increasing the risk of accidents.
In addition, the oily residues left by WD40 could attract more dirt and dust, thus worsening the condition of the brakes in the long run.
Specific products for brake cleaning
If you are looking to clean and maintain your brakes safely, it is advisable to use products specifically designed for this purpose.
The famous brake cleaner is just what we are looking for. It is not particularly expensive, leaves no greasy residue, and is one of the best degreasers out there. These brake cleaners are formulated to remove grease, dust, and other debris without affecting the effectiveness of the brake system.
However, WD40 itself does sell brake cleaner products under its brand, as the success garnered by its standard product has led the company to diversify its product line. In any case, WD40 Brake Cleaner is recommended exclusively for motorcycles, so we still recommend that you use a product from another brand, such as the one we have left for you in the link.
What conclusions do we draw?
Although WD40 is a useful product for many maintenance tasks, its use in cleaning a car’s brakes is highly discouraged. To ensure safe driving, it is best to resort to specific products or the services of professionals in the field of automotive mechanics.
In any case, the fact that there are brake cleaner products under the WD40 brand itself can lead to confusion.
