What wash soap to use in step in tub.?

For step-in tubs, it's best to use a mild, non-abrasive soap specifically formulated for bathing purposes. Look for products labeled as body wash or bath gel that are free from harsh chemicals, fragrances, and dyes to prevent irritation. Avoid using regular household soaps or detergents, as they can leave residues and may not be suitable for skin contact. Always check the manufacturer's recommendations for your specific tub model for any specific soap guidelines.
