What is recommended for treating stains and discoloration of interior linings in reefer containers?

Using a hot high-pressure wash is recommended for treating stains and discoloration of interior linings in reefer containers because it effectively removes substances without causing harm to the lining material. The high-pressure water helps to dislodge and remove dirt, mold, or other residues that can accumulate inside the container, particularly in a refrigerated environment where moisture can lead to staining.

This method is advantageous because it does not involve the use of harsh chemicals that could potentially damage the lining or leave behind harmful residues. It is also efficient for completing the cleaning process quickly and thoroughly, ensuring the container is sanitary for use.

Other methods, like scrubbing with detergent or applying bleach, may not be suitable for all lining materials and could cause further damage or discoloration. Replacing the lining is a more drastic measure that would typically be reserved for when the lining is beyond cleaning or has suffered significant damage. Thus, the hot high-pressure wash stands out as the optimal choice for maintaining the integrity and cleanliness of reefer container interior linings.
