Review on 🧴 Thetford Blaster Holding Tank Cleaner Pouches, 1.6 oz., White - Pack of 4 by Will Porter

Bought this product to clean my two gray tanks and one black tank. Starting with my black tank. This tank has never contained solid waste. No paper, no hard stuff. The sensor's four indicator lights showed even when it was fully reset and I followed the instructions carefully. Leave overnight and drain the next morning. Let it dry for a few hours and check the level of the sensor. Four more headlights. This product did not clean anything at all. Definitely no sensors. So the next day I met one of the gray tanks. In short, the results were the same. Two lightbulbs on the tank. Two bulbs after cleaning and this after using TWO detergents. I absolutely do not recommend this product.
