Not all cleanroom esd shoes can be cleaned
Recently, a customer intends to clean the dust-free shoes, but was rejected by our company. The reason is that the customer's dust-free shoes are particularly dirty, and the upper is basically oily, and it is impossible to clean without dust.
Why can't professional cleaning and cleaning of secondary dust-free shoes be cleaned?
1. Oil can not be removed, because the cleaning agent used for dust-free cleaning is neutral, only to ensure that water-soluble stains such as sweat, dust and dirt are removed.
2. If the bulk cleaning is similar to heavy-duty dust-free shoes, it will cause pollution in the purification workshop environment and purification equipment. (Note: Even if the cleaning boots should be cleaned after use, if the long-term use causes excessive contamination of the cleaning boots, this heavy-contaminated shoes will not be recommended as a purifying shoe in the future.)
3. We need to ensure that all customers' clean clothes are clean after cleaning, so they cannot clean shoes like heavy pollution.
Some non-professional dust-free cleaning companies use strong acid and alkali detergents in the process of cleaning clean clothes. Together with the powerful industrial washing machine, the clothes washed out are clean and beautiful, but the clothes themselves are seriously damaged, especially Special professional functional uniforms such as anti-static clothing and dust-free clothing, the conductive wire on the fabric will be strongly corroded and disintegrated, seriously affecting the performance of the clothing.
Our company uses special isolated drum washing machine, high-efficiency filter dryer, using two-stage RO water and 18 MΩ EDI ultra-pure water, and is equipped with professional purification non-ionic surface-active detergent to clean anti-static clothes and clean clothes. At the same time, it has a 100-level purification and cleaning packaging center. The folding, packaging, testing and temporary storage of the cleaned garments are all done in an ultra-clean environment.
