The Difference Between Surface Cleaning and Deep Cleaning

Not every "tank cleaning" is equal. There is a vast difference between a company that rinses the tank with water and leaves, and a company that carries out a thorough, methodical cleaning process. Knowing this difference will help you make the right decision.

What Is Surface Cleaning?

Surface cleaning is simply draining the water from the tank and then rinsing it with clean water. This method removes some loose sediment but leaves the bacteria and algae stuck to the walls and floor untreated. The result: a tank that looks clean but isn’t safe for health.

What Is Deep (Thorough) Cleaning?

Deep cleaning is a methodical, multi-stage process that ensures the removal of all types of contamination — visible and invisible. This type of cleaning requires specialized equipment and approved disinfectants.

The Deep Cleaning Stages at Crystaleh

• Initial inspection: assessing the tank’s condition and identifying the type of contamination
• Draining the water: fully pumping out all remaining water
• Mechanical scraping: removing sediment and algae stuck to the walls and floor
• Washing with disinfectants: using Ministry of Health licensed disinfectants
• Complete rinsing: washing the tank with clean water to remove any trace of disinfectant
• Drying and final inspection: confirming the tank is completely clean before refilling

A Quick Comparison

• Surface: 20-30 minutes — Deep: 1-3 hours depending on size
• Surface: removes loose sediment only — Deep: removes all types of contamination
• Surface: uses no disinfectants — Deep: Ministry of Health approved sanitization
• Surface: no guarantee on the result — Deep: full guarantee on cleaning quality
