Why Cold Room Cleaning Is Critical
Standard cleaning methods fail in refrigerated environments - here's what makes KARL different
| Critical Factor | Standard Cleaning | KARL Cold Room Cleaning |
|---|---|---|
| Temperature capability | Room temperature only, requires shutdown and warm-up (12-24 hours) | Work in -25°C to +4°C, no shutdown required, cold chain maintained |
| Chemical effectiveness | Standard chemicals freeze or lose efficacy in cold | Cold-tolerant FSANZ chemicals designed for low temperatures |
| Mold treatment | Surface cleaning only, mold returns within weeks | Thermal fogging + fungicide + moisture control = 6-12 month protection |
| Ice buildup management | Mechanical scraping, risks surface damage | Controlled thawing, safe removal, drain cleaning, root cause resolution |
| Staff training | No cold environment training | Cold room safety certified, hypothermia prevention, PPE specialized |
| Product safety | Cross-contamination risk during warm-up/cool-down | Product remains refrigerated, no temperature abuse, full traceability |
| Cost of downtime | $5,000-20,000+ in shutdown costs and product loss | Zero downtime, clean during off-shifts, production continues |

Frequently Asked Questions
How do you remove mold from cold rooms?
Our mold removal process includes: (1) Thermal fogging with anti-fungal agents that penetrate surfaces, (2) High-pressure washing at controlled temperatures, (3) Application of food-grade mold inhibitors, (4) ATP testing for verification, and (5) Addressing moisture sources causing mold growth. All chemicals are FSANZ-approved for food contact surfaces and remain effective in cold temperatures.
Can you clean cold rooms while they're operational?
Yes, we specialise in temperature-safe cleaning that maintains cold chain integrity. Our technicians are trained to work in temperatures as low as -25°C, using specialised cold-tolerant equipment and procedures that don't compromise product safety or temperature control during cleaning. This eliminates costly warm-up/cool-down cycles and prevents product loss.
What causes mold in cold rooms if bacteria can't grow in cold?
While bacteria growth slows dramatically in cold, mold spores can germinate at temperatures as low as -5°C. Mold thrives on: (1) Moisture from condensation, (2) Organic matter (food residues), (3) Poor air circulation, and (4) Temperature fluctuations. Even small temperature swings during door openings create condensation that feeds mold growth. This is why dedicated cold room cleaning with anti-fungal treatment is critical.
How often should cold rooms be deep cleaned?
Frequency depends on several factors: High-risk areas (meat, seafood, dairy): Monthly deep clean. Medium-risk (produce, bakery): Quarterly deep clean. Low-risk (dry goods, packaged): Semi-annually. However, if you notice any visible mold, excessive ice buildup, or odors, immediate cleaning is required regardless of schedule. We provide customised maintenance plans based on your specific products and risk assessment.
What PPE do your technicians wear in cold rooms?
Our cold room cleaning technicians wear specialised cold environment PPE including: insulated coveralls rated to -30°C, thermal gloves with grip coating, insulated safety boots, balaclava or face protection, safety glasses (anti-fog), and cold room safety harness for emergency situations. All staff are trained in hypothermia prevention and cold room emergency procedures.
Can you clean cold rooms with product still inside?
Yes, but with careful planning. We use protective sheeting to isolate product, work section-by-section to minimise exposure, and use food-grade chemicals with no-rinse options for areas near product. However, for optimal results and to prevent any risk of cross-contamination, we recommend scheduling deep cleans during scheduled inventory rotations when cold rooms can be emptied or substantially reduced.
