"I can't see that it really does anything besides clean the bowl, which it does nicely, but i don't need a special product just for that. I don't see that it has any effect on the hard-water stains."
"We bought a used motorhome and it has stains in the holes where the water flushes around the bowl as well as stains on the ball valve. I used this toilet cleaner as directed. Followed directions to a T. Used it two days in a row. Did not clean as I hoped. Maybe all these great reviews are from ones who do not use their RV’s much. I do not know. We live in ours full time. I ended up using bar keepers friend and a green scratcher to get most the black stains off and white vinegar to clean the ball valve. Ball valve is better than it was, but not what I would like to see. So, I bought 3 bottles of the toilet cleaner. I will use it till gone but will not purchase again. My hopes were high for this product 😔"
"I love this product. Easy to store in the RV and use. Smells great, works great. I love the dry packs for space savings. We are all about the space savings in the RV. . ."
"Easy to use, we are full time rv boon dockers while we are building our forever home and have been using unique products for the last 3 years. Very happy with how easy this is, even my 10 year old son doesn’t mind helping clean the toilet every once in a while since the foam is “cool!”"
"TANKRANGERS associate Steve dropped off some samples of RV Digest-IT and SCRUB-IT at my camper the other day to let me try them out and that’s the best result I’ve gotten in the last two years I was sold looking forward to my next purchase"
"excellent product would recommend - got my take cleaner than its ever been"
"We have owned our RV for 7 years now and didn’t start using Unique products at first but wouldn’t use anything else now. The scrub it bowl cleaner works great. We also use the Digestit for our tank additive and recommend both products ."
