Prewash: The Key Step to Saving Cleaning Chemicals and Elevating Hygiene Standards in Back of House

📌 What is Prewash?

Prewash is the initial cleaning step in a restaurant’s Back of House (BOH) areas—such as kitchens, dishwashing zones, and food prep areas. It involves rinsing with water or using mild bio-based cleaning products to remove large food debris, grease, and surface soil before moving to the main cleaning and sanitizing stage.

🌟 Benefits of Prewash in Back of House

✅ 1. Reduces the Amount of Main Cleaning Chemicals

If large food residues and grease are not removed first, more cleaning chemicals will be required later as they are used to break down heavy soils instead of reaching deep-seated biofilms.
🔹 Result: Prewashing helps reduce cleaning chemical use by 20–30% per cycle, leading to significant monthly cost savings.

✅ 2. Enhances Cleaning Efficiency

By clearing away bulk residues, detergents and sanitizers can penetrate and act directly on microscopic contaminants and tough stains.
🔹 Result: Surfaces are thoroughly cleaned, odors are reduced, and hygiene standards are improved.

✅ 3. Saves Time and Labor Costs

Soaking or spraying during prewash softens hardened residues, making scrubbing less labor-intensive and speeding up the cleaning process.
🔹 Result: Staff complete cleaning tasks faster, reducing labor time and costs.

✅ 4. Prevents Drain Blockages and Odors

Removing food residues before washing prevents them from entering drains, reducing clogging and unpleasant odors in the BOH.
🔹 Result: Better wastewater management and improved kitchen hygiene.

✅ 5. Supports Sustainable Cleaning Practices

Using a surface and cookware cleaner like K103 Dish, Pot & Pan Cleaner in prewash helps:
🌱 Minimize chemical residues in wastewater
🌱 Reduce workers’ exposure to harsh irritants
🌱 Lower the restaurant’s Carbon Footprint because plant-based surfactants produce less foam and require less water for rinsing
