Cleaning/protecting liquid for motors

The maintenance of the motor is also part of the preparation

When a motor loses performance, the most common cause is not wear but the accumulation of dirt, carbon deposits, and residues in its internal components. The SISP41 from Slot.it is a liquid specifically formulated to clean and protect slot car motors, restoring smooth rotation and helping to preserve internal parts against corrosion and accelerated wear.

Main features

• Double action: cleans accumulated residues and dirt while simultaneously depositing a protective layer on the motor components.
• 50 ml format: generous amount for prolonged maintenance, suitable for both home use and slot clubs.
• Product from the Slot.it brand: developed by one of the leading manufacturers in the competitive slot racing world, who understands the demands of their own motors firsthand.

Recommended applications

The SISP41 is designed for the periodic maintenance of slot car motors, especially those that accumulate many hours of running or are used under high-demand conditions. A few millilitres applied correctly can make a noticeable difference in the smoothness of rotation and the motor's response.

It is also useful when acquiring a second-hand car or when reviving a motor that has not been used for a while, as it helps to remove dry residues and reactivate internal lubrication.

Usage recommendations

• Apply the liquid sparingly: a few drops are sufficient. Excess can attract more dirt or affect the braids.
• Let it sit for a few seconds and, if possible, run the motor idle to distribute the product well.
• Repeat the process periodically, especially after long racing or competition sessions.
• Store the container tightly closed and away from heat sources.

Ideal for…

Any enthusiast who wants to get the most out of their motors and avoid premature replacements. Also highly recommended for preparers and club racers managing multiple cars who need a reliable and easy-to-apply product in the workshop or pit lane.

Frequently asked questions

Is it compatible with all slot car motors?

It is designed for slot car motors in general. As a Slot.it product, it has been specifically tested with their own motors, although its regular use in the sector encompasses motors from various brands. If you have doubts about a very specific motor, please consult us first.

How much product should I apply each time?

A few drops are more than sufficient. Applying too much liquid can be counterproductive, as the excess could reach the braids or the collector and cause electrical contact issues.

How often should I use it?

It depends on the use of the motor. In competition or intensive use, maintenance every few sessions is common. In recreational use, every certain number of hours of running or when you notice that the motor is running less smoothly.

Does it also work for cleaning very dirty or seized motors?

It can help loosen dry residues and accumulated dirt, but if the motor is very deteriorated or blocked, a more thorough mechanical cleaning may be necessary before applying the product.
