⚠ Baking Soda + Vinegar
Used separately, both can have helpful cleaning properties — but combined, they neutralise each other and essentially produce water. This combination weakens both products and is not an effective cleaner.

💡 The golden rule: Please resist the urge to create a DIY super solution. Leave chemical mixtures to the professionals and use purpose-made products for each cleaning task. If in doubt, check the product label or safety data sheet before use.
