Hello ls0404,
Thank you for taking the time to leave us your thoughts on the Delta Faucet model 52664-BL. We appreciate your feedback.
I am sorry to hear that this product did not meet your expectations. As the manufacturer, we are committed to supplying our consumers with quality products that deliver the expected performance. Model 52664-BL has soft, rubber touch-clean spray holes which allow the user to easily wipe away any calcium and lime build-up from the spray face of the showerhead with the touch of a finger. Please try soaking your showerhead in a 50/50 solution of white distilled vinegar and water for up to 30 minutes to help loosen any possible calcium build-up. After the unit has finished soaking, pat it dry with a soft cloth.
If soaking your unit as recommended does not resolve your concern, please contact us directly at 1-800-345-3358 or customerservice@deltafaucet.com, as we would need to collect more information from you to assist you better.
Thank you for being a loyal Delta Faucet customer.
Best Regards,
Emma
Digital Communications Specialist
