Can Ajax stain a toilet seat?

Yes, Ajax can stain a toilet seat, particularly if it contains dyes or colorants. Additionally, if the cleaner is left on the surface for too long or not rinsed properly, it can cause discoloration. It's always best to check the manufacturer's recommendations for cleaning materials suitable for your specific toilet seat material. Using gentler cleaners or those specifically designed for toilet seats is advisable to avoid potential staining.
