    Use the multi-surface grease remover Before proceeding to clean the gas cap itself, it is essential to clean both the gas cap door and the surrounding area. Cleaning the gas cap alone might cause some of the fuel residuals to fall in the tank. Opt for a spray or aerosol degreasers so you can easily focus on such a limited surface without spilling over the side of your car.

    Dilute the product, so you have a blend of four parts of water and one piece of chemical remover to avoid damaging the painting. Wash it with a hose After spraying the degreaser on the gas cap door, allow it to rest for a few minutes for the best results.

Pick up your old cloth or rag and spread the lube across the surface through a scrubbing movement. By allowing it to work for a couple of minutes, this chemical will melt any hardened grease.

    Proceed to wipe the gas cap clean and repeat this step if necessary. Use silicone-based spray After you have cleaned the gas cap of the residues of the petroleum-based lube, cover it with a silicone-based spray. The first chemical will eventually damage the plastic of the gas cap if you have failed to remove it properly.

Issues Caused by a Dirty Gas Cap Dirty gas cap doors are out of sight for most of the day, and we usually end up forgetting that grease can build up in it, too.

    Moreover, some severe damages can derive from a dirty gas cap door. While it is easy to clean when the dirt first appears, the grime can extend to the fuel cap over time, making it difficult to open it and close it properly.

    Even worse, if the grease and dirt end up on the gas cup itself, you might be facing a much bigger issue. Indeed, it is likely that the residues contaminate the fuel and settle at the bottom of the tank, plugging the gas pump or filter.

    Having to replace these parts of your car might be expensive, both in terms of money and time. Instead, cleaning the gas cap door promptly as soon as it gets dirty is a quick and easy task that can save you a lot of frustrations later on. First off, what is the black stuff that you are about to clean?

    In most cases, it derives from residual fuel build-ups, and it is a mix of mildew and grease. If you are feeding your car ethanol-based fuel, you should be aware of the characteristics of this substance.

    However, ethanol tends to attract water and humidity particles from the surrounding environment. With ethanol-based fuel sitting in your tank most of the time, it is reasonable that moisture will build-up around the gas cap.

    Since this area does not benefit from a steady airflow, the moisture will quickly turn into black mildew. Additionally, the gas cap door is the part of your car that is continuously in contact with fuel, aside from the engine itself. However, unlike the engine, the fuel residual on this appliance tends to sit undisturbed for days or months.

    Without proper maintenance, this debris will spoil and turn to grease. Final Thoughts Cleaning the gas cap and the gas cap door are tasks that you can complete in under an hour. While we might keep postponing the cleaning day because this area is not one of the most visible ones, keeping your gas cap door clean and free of debris is essential. Indeed, failing to provide it with regular maintenance can lead to contamination of the gas in the tank. Related Articles.
