What is the recommended cleaning method for heavy soil on plastic guards?

Soaking the item in warm water for 15-45 minutes is effective for heavy soil on plastic guards because it allows the dirt and grime to loosen and disperse from the surface. Warm water aids in breaking down the oils and particulates that may be clinging to the plastic, making it easier to clean without causing damage to the material. This method is generally safe and non-abrasive, which is particularly important for maintaining the integrity of the plastic components used in electrical systems.

While other methods can be somewhat effective, they may not provide the same level of thoroughness. For instance, wiping with a dry cloth may simply push the soil around rather than removing it, and rinsing under cold water may not be sufficient to dislodge stubborn dirt. Using a chemical cleaner might risk damaging the plastic or leaving behind residues that could attract more dirt over time. Therefore, soaking in warm water strikes the right balance of effective cleaning while preserving the material's condition.
