What should be used to remove tar, oil, and grease from ladders?

Using safety solvents to remove tar, oil, and grease from ladders is the most effective and appropriate choice. Safety solvents are specifically designed to break down tough substances such as grease and oil without damaging the underlying material of the ladder. These solvents often evaporate quickly and leave little or no residue, ensuring that the ladder is clean and safe for use.

In contrast, while soap and water might help with general cleaning, they are usually not sufficient for heavy deposits of tar or grease. Alcohol can be effective for certain types of cleaning but may not be powerful enough against stubborn substances like tar and grease. Paint thinner is also not advisable for cleaning ladders, as it is too harsh and could potentially damage the ladder’s finish or structural integrity. Thus, safety solvents provide a balance between efficacy and safety, making them the best option for this specific cleaning task.
