Customer Reviews
Works well, arrived fast
Bought the Solbio 1.6 litre pouch. Product works as described in my portable toilet. Delivery was quick, got it in 3 days. No complaints.
Good fluid, slow shipping
I picked up the Solbio 5 litre container last month. The product itself, the organic toilet fluid, is excellent. It handles odors well in our caravan and it's nice knowing it's not harsh chemicals. For that, it's a solid 5 stars. However, shipping took a bit longer than I expected, around 7 business days to reach my address. It wasn't a huge deal since I wasn't in a rush, but something to note if you need it quickly. Packaging was fine, no leaks. I'd definitely buy the fluid again for its effectiveness, but I'll plan ahead for delivery next time.
Great product, good delivery
I ordered the Solbio 1.6 litre pouch for my motorhome a couple of weeks ago. The ordering process on their site was straightforward, no issues there. It shipped out pretty quickly and arrived within 4 days, which I thought was reasonable for a standard delivery. I've used it now on a weekend trip, and it definitely kept odors down in the cassette toilet. The fluid itself seems effective, and I like that it's organic. It's easy to pour and not messy. I had a quick question about using it in the grey water tank, so I sent an email to their support. They got back to me the next day with a clear answer. Overall, a positive experience.
Amazing stuff!
I just got my Solbio 1.6 litre pouch and wow, it's fantastic! I've been looking for an eco-friendly option for our boat's waste tank and this is it. It smells good, not like those awful chemical ones. I'm so happy I found this. It's totally biodegradable and works perfectly. I will absolutely be shopping here again for more! You guys are doing great!
Got the large container
So I grabbed the Solbio 5 litre container for our RV, you know, to try something different from the blue stuff. It was pretty easy to order on their site. The package showed up about five days later, all good, no spills or anything. Used it on our last trip and it seemed to do the trick, kept things smelling fine in the toilet. It's nice not dealing with those strong chemical smells anymore. Definitely felt like a good switch.

Hey, how does Solbio compare to Thetford? I've always used Thetford but looking for something more eco-friendly.
Can Solbio be used in a regular septic tank system? Our holiday home has one and I wanna make sure it won't mess anything up.
Are there any active discount codes around for Solbio? Looking to buy a bigger pack.
Hey guys, thinking of trying Solbio for our motorhome. How long does a pouch usually last for a couple on a trip?
What's the deal with returns? Like if I buy a big one and don't like it, can I send it back easily?
