Yes! Always follow the instructions provided by manufacturers carefully when using these products, as they contain potentially hazardous materials if not handled properly. Things like chlorine can be irritating to the skin and eyes, so proper care is crucial. Also, it’s essential to remember not to add too much product to the water at once, as this could lead to excessive foaming or staining. Also never mix different types of chemicals unless you're 100% sure of what you're doing or have received professional guidance.
