FAQs

Can LM 40 be used on rubber seals?

Yes, LM 40 can be used on rubber seals to help maintain them and prevent drying out. However, always test on a small, hidden area first to be sure.

Is LM 40 safe for use on painted surfaces?

LM 40 is generally safe for most painted surfaces, but it's recommended to test on an inconspicuous area first to avoid any potential discoloration or damage.

How long does the lubrication effect last?

The duration of the lubrication effect depends on the application and environmental conditions. For heavy-duty or constantly moving parts, reapplication may be necessary periodically.

Can I use LM 40 to lubricate a bicycle chain?

Yes, LM 40 can be used to clean and loosen a bicycle chain. For optimal long-term lubrication for cycling, consider using a dedicated bicycle chain lubricant after cleaning with LM 40.

Does LM 40 displace water effectively?

Yes, LM 40 has excellent water-displacing properties, making it useful for protecting metal parts from moisture and preventing rust.

What is the difference between the 200ml and 400ml cans?

The primary difference is the volume of product. The formulation and intended uses are the same across different sizes of LM 40.

Troubleshooting

Spray nozzle is blocked

Remove the extension tube and clean it with warm water and a thin pin. Ensure the main nozzle is clear.

Product not loosening rusted parts effectively

Allow more time for the product to penetrate. Reapply if necessary. For severely rusted parts, mechanical removal might be required after treatment.

White residue left after application

This can occur with heavy application. Wipe away excess residue with a clean cloth once the product has worked. Ensure the can was shaken properly.

Odor is too strong

Ensure good ventilation during application. The odor will dissipate as the product dries and the solvent evaporates.
