With its powerful motors and large capacities, it is an ideal choice for efficiently handling bulk mixing tasks. Check out our Mixers here.  

What Are Gastronorm Pans? 

Gastronorm variants (GN pans) are standardised receptacles utilised in professional workspaces for preparing, storing, ferrying, and serving meals. They come in many dimensions and depths, all based on the European EN 631 benchmark. 

Common Sizes: 

• GN 1/1 (530 × 325 mm) - Full-size, ideal for ovens and bain-maries 

• GN 1/2 (325 × 265 mm) - Half-size, wonderful for meal creation and cold storage 

• GN 1/3 (325 × 176 mm) - Smaller portions, sauces, toppings 

• GN 1/6 (176 × 162 mm) - Garnishes, spices, sauces 

Materials: 

• Stainless Steel: Durable, heat-resistant, corrosion-resistant 

• Polycarbonate: Lightweight, transparent, ideal for cold storage 

• Polypropylene: Opaque, chemical-resistant, budget-friendly 

Why Maintenance Matters? 

Neglecting your gastronorm containers with leads can lead to: 

• Scratches, dents, and warping 

• Bacterial buildup and food contamination 

• Reduced working period and replacement costs 

• Poor presentation and customer perception 

Proper maintenance ensures hygiene, safety, and long-term ROI on your equipment investment. 

Daily Cleaning Tips 

1. Rinse Immediately After Use 

Don’t let food residues dry and harden. Rinse pots with warm water as soon as they’re emptied to prevent sticking and staining. 

2. Use Mild Detergents 

Do not use harsh agents like bleach, ammonia, or acidic sanitisers. These can corrode stainless steel and degrade plastic trays. 

3. Scrub Gently 

Use non-abrasive sponges or brushes. Steel wool and abrasive pads can scratch surfaces, creating grooves that are conducive to bacterial growth. 

4. Soak for Stubborn Stains 

For baked-on food or grease, soak the gastronorm pans for sale in hot water with a degreaser for 15–30 minutes before scrubbing. 

5. Rinse Thoroughly 

Leftover soap can cause discolouration or affect food safety. Always rinse with clean water after washing. 

6. Dry Completely 

Use a soft cloth to dry the containers immediately. Air drying can leave water marks or result in corrosion on stainless steel. 

Deep Cleaning Hacks 

Baking Soda Paste 

Combine baking soda with water to make a gentle abrasive paste. Apply with a microfiber cloth to remove stains without scratching. 

Vinegar Solution 

Dilute white vinegar with water and wipe down inserts to remove clingy stains and odours. Avoid using on aluminium or coated surfaces. 

Crushed Chalk (Blanc de Meudon) 

This natural calcium carbonate powder can be mixed with water to clean stainless steel pans. Apply the product, let it dry, and then buff off the excess with a sterile cloth. 

Storage Tips 

1. Stack Smart 

Stack dishes by size and depth to save space—but avoid overstacking, which can cause warping or cracking. 

2. Use Pan Covers 

When you buy gastronorm pans online, you will find that lids protect contents and prevent contamination. They also reduce moisture loss and help stack pans more securely. 

3. Label Clearly 

Use waterproof labels to identify contents and dates. This step improves inventory rotation and reduces food waste. 

4. Avoid Nesting Wet Pans 

Moisture trapped between nested pans can lead to rust or mould. Always dry the appliances before stacking. 

Usage Tips 

1. Match Pan to Task 

Don’t use polycarbonate variants in ovens or under heat lamps. Use stainless steel for food preparation and plastic for chilled storage. 

A durable and efficient product, which makes it ideal for high-volume cooking environments. Its superior heat distribution and retention ensure consistent, high-quality results. Check out our Commercial Cookware collection.  

2. Avoid Thermal Shock 

Don’t move containers directly from freezer to oven or vice versa. Sudden temperature fluctuations can cause plastic to break or metal to bend. For more information, visit the leading gastronorm pans suppliers and manufacturers in Australia. 

3. Use Inserts and Dividers 

These help organise ingredients and reduce cross-contamination. They also minimise wear from constant scraping or scooping. 

4. Rotate Pans 

Use all trays in rotation to prevent uneven wear and tear. This step is crucial in high-volume kitchens. 

Safety and Hygiene Tips 

1. Sanitise Regularly 

Use food-safe sanitisers after cleaning, especially for trays used in the preparation of raw food. 

2. Inspect for Damage 

Check pans weekly for cracks, warping, or rust. Broken containers can contain bacteria and sabotage meal safety. 

3. Follow HACCP Guidelines 

Ensure your cleaning and storage protocols align with Hazard Analysis and Critical Control Points standards. 

Material-Specific Care 

Stainless Steel 

• Avoid chlorine-based cleaners 

• Dry immediately to prevent rust 

• Polish occasionally with stainless steel cleaner 

Polycarbonate 

• Don’t use in high-heat surroundings 

• Avoid abrasive scrubbers 

• Keep away from direct sunrays to avoid colour loss. You can also consult with top gastronorm pans distributors and sellers. 

Polypropylene 

• Resistant to chemicals but not heat 

• Clean with mild soap and warm water 

• Avoid stacking heavy items on top 

Equipment That Helps 

Commercial Dishwashers 

Use models with adjustable racks and gentle cycles for GN variants. Avoid high-pressure jets that can damage plastic. 

Drying Racks 

Invest in vertical drying racks to air-dry inserts efficiently without the need for stacking. 

Pan Trolleys 

Use GN-compatible trolleys for transport and storage. They reduce handling damage and improve workflow. 

Pro Tips from Industry Experts 

• Always train staff on pan care during onboarding. It’s a small detail that saves thousands over time. 

• Colour-code your tray lids to match storage zones—red for raw, blue for cooked, green for produce. 

• Once a month, do a ‘comprehensive audit’ to check for damage and deep clean everything. 

• Use the liners of gastronorm containers with lids for sticky or acidic foods. Liners reduce residue buildup and protect surfaces, especially in high-turnover prep stations. 

• Avoid stacking pans when hot. Let the container cool before nesting to stop bending or twisting and moisture accumulation between surfaces. 

• Store the trays upside down. This step prevents dust and airborne particles from settling inside, especially in open shelving units. 

Common Mistakes to Avoid 

• Please do not use bleach or ammonia, as it results in corrosion and discolouration. 

• Avoid scrubbing with steel wool, as it can scratch the equipment and lead to bacterial buildup. 

• Do not hold wet pans as they result in corrosion and mould development. 

• Do not overheat plastic variants as they can warp and crack. 

• Do not ignore damage, as it can be a food safety risk.

Conclusion 

Gastronorm pans may not be flashy, but they’re foundational. With a bit of care and consistency, these workhorses can serve your kitchen for years—keeping food safe, operations smooth, and costs low. 

So next time you reach for a gastornorm container with lid, remember: it’s not just a container. It’s a cornerstone of your culinary craft.
