3. Selecting Appropriate Cleaning Solutions
While water pressure alone can remove many contaminants, certain cleaning solutions can enhance effectiveness, especially for oil stains and stubborn grime.
- Biodegradable Detergents: These are environmentally friendly and effective at breaking down grease and oil. The Environmental Protection Agency (EPA) recommends using products that are safe for both users and the environment.
- Acidic Solutions: For heavy staining, a diluted acidic solution can help restore the concrete’s appearance. However, caution is necessary to avoid damaging the surface.
4. Conducting Pre-Cleaning Inspections
Before pressure washing, a thorough inspection of the garage should be conducted. This includes:
- Assessing Structural Integrity: Check for cracks, spalling, or other signs of damage that may require repairs before washing.
- Identifying Hazardous Materials: Look for areas with oil spills or other hazardous materials that may need special handling.
5. Post-Cleaning Inspections
After pressure washing, a follow-up inspection is essential to ensure that the cleaning process did not inadvertently cause damage and that all areas have been adequately cleaned.
