Car Key Fobs – Maintenance Tips

2- Keyboards and cell phones accumulate skin oil from the fabric of your cloth and microscopic bits of skin, so when your key fob is placed in your pocket, it’s very likely to pick up this oil and dirt from the accessories in your pockets.

Using key fob cases helps to drastically reduce the chances of getting soiled or dirty from sweat or grime from our palms or clothes. Some of these key fob cases protect the key fob buttons as well.

2- Do not overindulge on the solvent. You should be wary about the amount of solvent you apply on your clean rag or paper towel to prevent the solvent from seeping into the key fob from the surface.

3- For strong solvents such as Acetone, ensure you perform the scrubbing of your key fob away from any furniture close by to avoid it getting ruined if an accident should happen.
