The white edges on terracotta pots can be removed without chemicals by using a mixture of equal parts water and white vinegar. Simply dip a clean cloth or sponge into the vinegar solution and gently scrub the white edges of the pot. The acidic nature of the vinegar helps to dissolve and remove the white residue without the need for harsh chemicals. After scrubbing, rinse the pot with water to remove any remaining vinegar solution. **

One way to remove the white edges from terracotta pots without chemicals is to gently scrub the affected areas with a mixture of water and vinegar using a soft brush or sponge. Another method is to create a paste using baking soda and water, then apply it to the white edges and scrub gently. Additionally, soaking the pots in a mixture of warm water and lemon juice can help to loosen and remove the white residue. Remember to rinse the pots thoroughly after cleaning to remove any remaining residue. **

PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been widely used in various industrial and consumer products since the 1940s. They are known for their water and oil repellent properties, and are commonly found in products such as non-stick cookware, food packaging, stain-resistant fabrics, and firefighting foams. PFAS chemicals are concerning because they are persistent in the environment, can accumulate in the human body, and have been linked to various health issues including cancer, immune system dysfunction, and reproductive problems. Due to their widespread use and potential health risks, there is growing concern and regulatory action to address PFAS contamination and exposure. **
