Review: Works well in Texas heat - Works well in gray tank for RV. No odors. Will buy again
Review: Works. Expensive... but it works... - This stuff works. We suffered for an entire Texas summer in our RV before discovering this stuff. Now we use it in the sink and bath tanks liberally combined with the regular pod / chemical you use in those tanks and even in the dead of a southern summer there are zero smells. The cost adds up if you use it liberally like I do, but again, it truly works. I just can't deal with grey water smell. Now I don't have to ever again. Win.

### ⭐⭐⭐⭐⭐ Works well in Texas heat

### ⭐⭐⭐⭐ Smells good going down. Weird coming back up.
*by C***H on October 17, 2017*

Seems to work. It gasses off this weird smell during treatment tho. It's only noticeable if you leave your RV for awhile and come back, in minutes it's unnoticeable as you get used to it. Love thetford products and wish I could give it 5 stars, but that smell was really strange. Was gone after dumping thankfully. At least it does seem to get rid of that nasty old grease smell, so it could be worse.
