Corrosion on metal parts of a scrubber can lead to costly repairs and unexpected downtime. For logistics managers who depend on reliable cleaning equipment every day, preventing corrosion is crucial to maintain large surfaces without interruptions.
By taking the right preventive measures, you can significantly extend the life of your scrubber and avoid expensive replacement costs. In this article we discuss the main causes of corrosion and provide practical tips to optimally protect your cleaning equipment.
What causes corrosion to parts of a scrubber?
Corrosion of parts of a scrubber is mainly caused by exposure to moisture, oxygen and chemical cleaning agents. This combination of factors causes oxidation of metal surfaces, resulting in rust formation and material degradation.
The working environment of a scrubber promotes corrosion due to several factors. Constant contact with water and cleaning agents creates a moist environment in which metal parts are vulnerable. Harsh chemicals in cleaning products can accelerate the corrosion process, especially when left on metal surfaces for long periods of time.
Temperature fluctuations also play a role in corrosion formation. When machines are moved from warm to cold environments, condensation can occur. This moisture settles on metal parts and creates ideal conditions for rust formation.
Which metal parts of a scrubber are most sensitive to corrosion?
The parts most vulnerable to corrosion are brush motors, water supply pipes, screw connections and the scrubber chassis. These components come into direct contact with water and chemicals during the scrubbing process.
Brush motors are particularly sensitive because they contain electrical components that operate in a humid environment. Water can penetrate engine housings and cause corrosion to internal metal parts. This can lead to engine failure and costly repairs.
The water tank system, including pipes and fittings, is another risk point. Residual water left behind after use can stagnate and cause corrosion. This risk is especially increased for machines that regularly work with acidic or alkaline cleaning agents.
Screw connections and fasteners are often made of steel and rust quickly when the protective coating is damaged. The chassis and frame of the machine can also develop corrosion, especially in areas where the paint has worn off through normal use.
How do you clean a scrubber to prevent corrosion?
Thorough cleaning after each use is essential for corrosion prevention. Rinse out all water tanks, clean the brush chamber and dry exposed metal parts to remove moisture that can cause corrosion.
Start by emptying both the clean and dirty water tanks. Drain the tanks completely and rinse them with clean water to remove cleaning agent residue. These chemical residues can otherwise have a long lasting effect on metal parts.
Clean the brush chamber thoroughly by rinsing it with clean water. Remove dirt and debris that can build up and retain moisture. Pay particular attention to corners and hard-to-reach places where water can remain.
Dry all accessible metal surfaces with a clean cloth. Pay extra attention to screw connections, hinge points and other places where water can collect. For optimal protection, you can treat these parts with a light oil or a corrosion protection agent.
Which protective equipment helps against corrosion on scrubbers?
Corrosion protection spray, marine grade lubricants and wax-based coatings provide effective protection against corrosion. These products form a protective barrier between metal surfaces and moisture, preventing oxidation.
Corrosion protection sprays are ideal for hard-to-reach areas, such as engine compartments and internal mechanisms. These sprays displace moisture and leave a protective film. Apply them monthly to vulnerable metal parts for optimal protection.
For moving parts, such as hinges and rotating parts, marine-grade lubricants are the best choice. These products are specially developed to resist moisture and remain effective longer than standard lubricants.
- Corrosion protection spray for electrical components
- Marine grade grease for bearings and hinges
- Wax coating for the chassis and frame
- Zinc spray for damaged painted surfaces
How often should you check a scrubber for corrosion?
Check your scrubber weekly for early signs of corrosion and perform a thorough inspection monthly. These regular checks help detect minor corrosion problems before they turn into costly repairs.
During the weekly check, look for visible rust spots, discoloration of metal surfaces and white rashes that indicate corrosion. Be sure to check areas where water can collect, such as around tanks, pipes and in the brush chamber.
The monthly thorough inspection includes checking less visible parts. Look at the underside of the machine, inspect electrical connections and check the condition of protective coatings. Document any findings to identify patterns in corrosion formation.
For intensive use in aggressive environments, such as industrial kitchens or chemical facilities, it is advisable to increase the checking frequency to twice a week. The investment in regular checks does not outweigh the costs of unexpected repairs and production disruptions.

Frequently asked questions
What should I do if I have already discovered rust spots on my scrubber?
Treat small rust spots immediately with a rust converter and then apply a protective coating. In case of extensive corrosion, it is wise to seek professional help to assess whether parts need to be replaced. Early treatment prevents the corrosion from spreading to other metal parts.
Can I use common household products to protect my scrubber from corrosion?
While some household products may help temporarily, we recommend professional corrosion protection products for optimal results. These have been specially developed for industrial applications and provide long-lasting protection. WD-40 can serve as a stopgap solution, but replace it with a suitable industrial product as soon as possible.
How long does it take for corrosion to become visible on a new scrubber?
Under normal conditions, corrosion can become visible within 3-6 months if preventive measures are not taken. In aggressive environments with a lot of moisture or chemicals, this can happen within a few weeks. That's why it's important to follow a preventative maintenance schedule from day one.
What signs indicate that corrosion has already caused serious damage to my machine?
Serious corrosion damage can be recognized by rusted parts, loosening screws, water leaks from tanks and pipes, or abnormal noises from the engine. If you notice white or green rashes on metal parts, or if parts feel brittle, immediate action is needed to prevent further damage.
Is it possible to make a scrubber completely corrosion-free?
Although you cannot eliminate corrosion 100%, you can drastically reduce the risk through consistent preventative maintenance. With proper cleaning, regular protection treatments and timely checks, you can extend the life of your machine for years. Invest in quality products and follow a regular maintenance schedule for the best results.
What are the costs of corrosion damage compared to preventive maintenance?
Preventive maintenance costs approximately 5-10% of the purchase price of your machine per year, while corrosion damage can lead to repair costs of 30-50% of the new price. Moreover, you prevent unexpected downtime and loss of production. A monthly investment of a few tens of euros can save thousands of euros in repairs.
