If the non-stick coating of your frying pans is coming off after just a few washes with dishwasher liquid and hot water, there could be a few reasons for this:
Poor quality or worn-out coating: Low-quality or worn-out non-stick coatings are more prone to peeling or flaking. Over time, repeated use, exposure to high heat, and aggressive cleaning can cause the coating to deteriorate. If the frying pans were of inferior quality or had a thin or damaged coating to begin with, it may explain why the coating is coming off so quickly.
Harsh cleaning agents or scrubbing: Even though you mentioned using dishwasher liquid and hot water, it's possible that the dishwashing liquid or scrubbing tool you're using is too harsh for the non-stick coating. Abrasive scrub brushes or cleaning agents, such as abrasive powders or scouring pads, can damage the coating and cause it to peel off.
Improper storage or stacking: Stacking or storing non-stick pans with other heavy cookware or utensils can lead to scratching or chipping of the coating. Over time, these scratches can compromise the integrity of the non-stick surface, making it more prone to peeling.
Overheating the pans: Exposing non-stick pans to extremely high heat can damage the coating. If the pans are consistently overheated, it can cause the non-stick surface to degrade and eventually come off.
To help prevent the non-stick coating from coming off prematurely, here are some tips:
Use gentle cleaning methods: Opt for mild dishwashing liquid and a soft sponge or cloth to clean the pans. Avoid abrasive scrub brushes or harsh cleaning agents that can damage the coating.
Avoid high heat: While non-stick pans are designed to handle moderate cooking temperatures, excessive heat can degrade the coating. Use low to medium heat settings to preserve the non-stick surface.
Store carefully: Avoid stacking non-stick pans together or placing heavy objects on top of them. Store them in a way that minimizes contact with other cookware or utensils to prevent scratching.
Invest in quality cookware: High-quality non-stick pans with durable coatings are more likely to withstand regular use and cleaning. Research and choose reputable brands that offer reliable non-stick cookware.
If the non-stick coating continues to peel off after just a few uses, it might be a sign of a manufacturing defect or poor-quality cookware. In such cases, contacting the manufacturer or considering a replacement may be necessary.
