We have been using Napco products for about 1.5 years now. Napco products have always exceeded our expectations. We primarily use their 320 Product lines. After we depleted our stock of their Poly Tub & Tile Prep we ordered their new tile preparation product (Piranha Prep). The Piranha Prep is a concentrated solution that cleaned the tubs very well without those harsh chemical odors.
So, on the behalf of Richardson HomeWorks LLC, we thank you for such an amazing Tub and Tile Prep.
