While all-purpose cleaners are versatile, there are certain surfaces and items they are not suitable for. Here are some things you should avoid cleaning with all-purpose cleaner:

1. Natural Stone Surfaces • Granite and Marble: All-purpose cleaners can dull the finish and damage the sealant on natural stone countertops. Instead, use a cleaner specifically designed for stone surfaces or a mixture of mild dish soap and water.
2. Wood Furniture and Floors • Unsealed or Waxed Wood: All-purpose cleaners can strip the finish and damage the wood. Use a wood-specific cleaner or a mixture of vinegar and water.
3. Electronics • Screens and Keyboards: All-purpose cleaners can damage electronic screens and keyboards. Use a screen-safe cleaner or a microfiber cloth dampened with water or a mix of water and isopropyl alcohol.
4. Stainless Steel Appliances • Streaks and Residue: All-purpose cleaners can leave streaks and residue on stainless steel. Use a stainless steel cleaner or a mixture of vinegar and water, followed by a dry microfiber cloth.
5. Cast Iron Cookware • Seasoning Removal: All-purpose cleaners can strip the seasoning off cast iron pans. Instead, clean them with hot water and a stiff brush, and avoid soap if possible.
6. Non-Stick Cookware • Coating Damage: All-purpose cleaners can damage the non-stick coating on pots and pans. Use a mild dish soap and a soft sponge.
7. Silverware and Silver Items • Tarnish and Damage: All-purpose cleaners can cause tarnish and damage to silver. Use a silver polish or a mixture of baking soda and water.
8. Mirrors • Streaks: All-purpose cleaners can leave streaks on mirrors. Use a glass cleaner or a mixture of vinegar and water.
9. Leather • Drying and Cracking: All-purpose cleaners can dry out and damage leather furniture, clothing, and accessories. Use a leather cleaner and conditioner.
10. Certain Fabrics and Upholstery • Stains and Damage: All-purpose cleaners can stain or damage delicate fabrics and upholstery. Use a fabric-specific cleaner or a mixture of water and a small amount of dish soap.
11. Automotive Surfaces • Interior and Exterior Damage: All-purpose cleaners can damage car interiors and exteriors. Use automotive-specific cleaners for these surfaces.
12. Antique or Delicate Items • Finish and Integrity: All-purpose cleaners can damage the finish and integrity of antiques and delicate items. Use a cleaner specifically designed for antiques or consult a professional.

Using the right cleaner for each surface ensures you maintain their appearance and integrity.
