Maintaining clean plastic water storage barrels is essential to keep drinking water safe and free from contaminants. This guide outlines a practical, step-by-step method using common cleaning tools designed for plastic drums and water storage barrels.
Whether you’re repurposing a barrel or maintaining a long-term storage system, following best practices helps prevent residue buildup, mold, and odor. The steps below emphasize safe handling, effective cleaning, and routine maintenance.
Quick Answer
Rinse the barrel with clean water, scrub with a dedicated drum cleaning kit and brush set, sanitize with a vinegar or non-chlorine solution, and thoroughly rinse before refilling. Always air-dry the barrel completely and store with the cap fully tightened to prevent recontamination.
What You’ll Need
- 55 gallon drum cleaning brush plastic handle
- drum cleaning kit for water storage barrels
- HDPE barrel cleaning brush wide mouth
- plastic drum scraper and scrubber set
- water storage barrel sanitation kit
Before You Start
Inspect the barrel for cracks or leaks, and ensure it is free of residual chemicals. Use gloves and eye protection when handling cleaning solutions. Work in a well-ventilated area if the barrel previously contained chemicals. Time estimate: about 45–90 minutes per barrel, depending on contamination level. Safety note: never mix cleaning agents such as bleach with ammonia or other cleaners; this can create dangerous vapors.
Step-By-Step: How To Clean Plastic Barrels For Water Storage
- Empty and rinse: Pour out any remaining liquid and rinse the barrel with clean water to remove loose debris.
- Initial scrub: Use the HDPE barrel cleaning brush wide mouth or the 55 gallon drum cleaning brush plastic handle to scrub the interior walls, paying attention to corners and the bottom.
- Target stubborn residue: Employ the plastic drum scraper and scrubber set to dislodge stubborn sludge or slime without scratching the surface.
- Rinse again: Thoroughly rinse with clean water until the water runs clear and no suds remain.
- Sanitize: Prepare a sanitizing solution following product directions (commonly a diluted vinegar solution or a non-chlorine sanitizer). Treat the interior surfaces and cap threads if accessible.
- Final rinse: Rinse the barrel again to remove all traces of the sanitizing solution.
- Drying: Place the barrel upright with the cap off or loosely tightened in a warm area to promote complete drying. Ensure all moisture evaporates before refilling.
- Reassembly and storage: Reattach any components, tighten the cap, and store the barrel in a clean, shaded area away from direct sunlight to minimize algae growth.
- Documentation: Note the cleaning date on the exterior for routine maintenance scheduling.
- Re-test water supply: After refilling, run a short flush to verify taste and odor do not indicate contamination.
- Periodic maintenance: Schedule professional sanitization if long-term storage or high-risk contents are involved.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent odor after cleaning | Residual cleaning agents or organic buildup | Extra thorough rinse and a fresh sanitizing cycle | Rinse promptly after each use; avoid overloading with organic material |
| Discoloration on walls | Biofilm or mineral deposits | Use a vinegar-based sanitizing rinse or specialized barrel sanitizer | Regular maintenance and prompt cleaning after each use |
| Cracks or leaks detected | Over-tightening or existing damage | Repair or replace the barrel as needed; avoid forcing caps | Inspect barrels before each use and store properly |
| Mold growth inside cap threads | Moist environments and poor drying | Clean threads with a brush and sanitize; ensure complete drying | Keep caps loosely closed during drying period |
Common Mistakes
- Using strong household cleaners not suited for food-grade barrels
- Rushing the rinse phase, leaving residual residue behind
- Using abrasive tools that scratch interior surfaces
- Failing to dry the barrel completely before storage
- Forgetting to sanitize after cleaning or before refilling
Sticking to the recommended tools helps prevent damage and ensures better sanitation outcomes. Visual checks during and after cleaning catch issues early.
Tips For Best Results
- Choose tools designed for food-safe plastic barrels to avoid introducing contaminants.
- Work with clean, potable water for rinses to prevent introducing impurities.
- Use a dedicated brush set to prevent cross-contamination with other containers.
- Label each cleaned barrel with the date and contents for simple tracking.
- For large barrels, consider a second person to assist with scrubbing and rinsing.
Call A Professional
Seek professional help if the barrel shows persistent leaks, deep cracks, or if the barrel stored hazardous contents in the past. If heavy contamination remains after multiple cleanings, contacting a water treatment professional or a sanitation service is advisable.
FAQ
How often should I clean a water storage barrel?
Clean at least every 6–12 months, or more frequently if it’s used for potable water under high-temperature conditions or exposed to debris.
Can I use bleach to sanitize plastic barrels?
Bleach can be used if the barrel is rated food-safe, but it must be properly diluted and thoroughly rinsed to avoid taste or chemical exposure. Follow manufacturer guidance.
What size brush works best for wide-mouth barrels?
Use a wide-mouth HDPE barrel cleaning brush designed to reach all interior surfaces without scratching.
Is it necessary to dry the barrel completely before refilling?
Yes. Complete drying reduces the risk of mold and bacterial growth during storage.
What if I don’t have a drum cleaning kit?
Any bottle brush or scrubber with a long handle can help, but dedicated drum cleaning tools ensure more thorough cleaning.
Can I store treated water long-term in a barrel?
Yes, but ensure the water is properly treated and the barrel is sanitized before filling; follow local health guidelines for long-term storage.
Buying Guide
When selecting cleaning tools and accessories for plastic water storage barrels, consider several factors to optimize cleanliness and safety.
Size and compatibility: Ensure tools fit the barrel’s neck and interior dimensions, especially wide-mouth designs. A kit that includes a HDPE barrel cleaning brush wide mouth and a 55 gallon drum cleaning brush plastic handle covers most common barrel sizes.
Material safety: Choose brushes and scrapers made from food-grade, non-scratching plastics to avoid contaminating potable water.
Cleaning versatility: A drum cleaning kit for water storage barrels and a plastic drum scraper and scrubber set offer multiple tools for different surfaces and residue types.
Sanitation options: Look for a water storage barrel sanitation kit that includes safe sanitizers and clear usage instructions to meet health standards.
Ease of use: Ergonomic handles and long reach reduce strain during cleaning, making maintenance quicker and safer.
Maintenance frequency: For households with frequent use, consider keeping a dedicated set on hand to streamline routine cleanings.
In practice, many households prefer a compact combination kit paired with a wide-head brush for interior scrubbing and a scraper for stubborn buildup. Regular maintenance, proper sanitization, and thorough drying are the core practices for keeping water storage barrels safe and ready for use. Have you scheduled your next barrel cleaning session?
