Review on 🚽 Walex Porta-Pak RV Black Tank Deodorizer Drop-Ins: Fresh Scent, Pack of 10 – Efficient Odor Control for RV Holding Tanks by Jay Kenville

We had the opportunity to use these deodorants in our home over the weekend and found them easy to use and effective. User reviews of this and other competing products. Now I'm going to add one of these after the reset along with a gallon or two of water. The ideal time for us is after the reset and cleaning, before the camper is put back into storage. Telling what happens during a short drive is great for dispersing the chemicals and gently spraying them around the black water tank. I've noticed that the smell can be from the tank drying out, so it makes more sense to me now. as it was quite strong the other day picking up a trailer from storage (and was washed prior to storage). Overall I find Pak easier to use than liquid and the smell is fresh.
