Pre-Treat or Post-Treat?
Do you pre-treat or post-treat and why?
Pre-treating before pressure washing is usually best. It softens and loosens stains, improves cleaning efficiency, and helps porous surfaces reach embedded grime. Post-treat or re-treat only if stubborn stains remain after the initial wash.
Short plan:
1) Apply a driveway-specific cleaner and let it dwell per label (usually 5–15 minutes).
2) Agitate if needed, then pressure wash.
3) Inspect. Target any remaining stains with a quick post-treatment and re-wash if needed.
Tips:
- Use the right cleaner for your stain (oil, mildew, dirt).
- Don’t let cleaner dry; keep it damp per instructions.
- Protect plants and rinse all residues.
