Cleaning Process

Key Guidance

Stage 1: Evaluation

You can discuss the material of object to be cleaned, type of contaminant, standard of cleanliness, condition of cleaning equipment, and impact on previous or next process for evaluation by phone call or in person.

Stage 2: Sample test cleaning

After confirmation of various conditions, we will provide professional judgment on the selection of detergent, conduct actual sample test, find out optimal cleaning conditions, parameters, and processes, and submit test report.

Stage 3: Actual test

We will provide samples to our customers for small-batch tests.

Stage 4: Joint development

When the test result does not reach the expected target, and both parties agree that it is necessary for our company to conduct the development of new detergent and conditions, they can sign the letter of intent for joint development.


How often should we replace the detergent?

The replacement cycle depends on actual types of contaminants, size of detergent tank, and detergent dilution ratio. The actual replacement frequency should be determined by professional personnel according to onsite situation.

How to choose from various cleaning detergents?

First of all, detergents can be divided into aqueous detergent, CFC detergent, petroleum detergent, and hydrocarbon detergent. There are pros and cons of various detergents. The aqueous detergent is equipped with the advantages of low price, strong detergency, and environmental protection. The comprehensive adaptability is better than other types of detergents. The only disadvantage is that it will require drying after cleaning. Therefore, we Burlan will implement the concepts of environmental protection and health to recommend aqueous detergent to replace organic solvent as our effort in environmental protection.

Will you have the complete solution for the cleaning process?

Burlan is a professional environmentally friendly detergent provider in compliance with the environmental protection laws and regulations following the global trend. We are proficient in the cleaning processes of various industries. We can provide our customers with overall cleaning process guides to help them improve yields, increase production capacity, and save costs. Feel free to contact us directly if you have any question related to cleaning.

Is the quality of detergent stable?

The quality control of our product has always been our first priority. The incoming material and delivery of every batch of products will be inspected to ensure the stable quality. We will regularly track customers usage situations and obtain feedback in order to provide necessary assistance and to solve our customers problems.

With reduced cost and increased production capacity, we replace organic solvents with water-based detergents such that we can contribute to environmental protection and health of employees.
