there are no commercially available nano ceramic coating liquids specifically designed for repairing damaged ceramic-coated cookware. Ceramic coatings on cookware are generally durable, but over time and with regular use, they may develop scratches or lose their non-stick properties.
If your ceramic-coated cookware has minor scratches or has lost some of its non-stick qualities, there are a few steps you can take to improve its performance:
Avoid metal utensils: Metal utensils can scratch the ceramic coating. Instead, use utensils made of wood, silicone, or plastic to preserve the coating.
Handwash gently: Avoid using abrasive scrubbers or harsh chemicals when cleaning your ceramic-coated cookware. Handwashing with mild soap and a soft sponge is recommended.
Seasoning: Some ceramic-coated cookware manufacturers suggest "seasoning" the pan occasionally to help maintain its non-stick properties. To do this, apply a small amount of cooking oil to the surface and then wipe off any excess with a paper towel.
Contact the manufacturer: If your ceramic-coated cookware is still under warranty or if you believe the damage is due to a manufacturing defect, contact the manufacturer for possible replacement or repair options.
If the damage to your cookware is significant or if it is beyond the warranty period, it might be best to consider purchasing a new piece of ceramic-coated cookware, as attempting to repair it with unconventional coatings or liquids could potentially compromise its safety and performance.
Please note that developments in technology and products may have occurred , so it's always a good idea to check with the manufacturer or do further research to see if any new products or repair methods have become available since then.
