Customer Reviews
Consistent quality, keeps me coming back
This was my third time ordering from Solbio, this time I got the 10 litre bulk pack. I've used their organic waste tank additive before and it's always been reliable. The consistency is what I appreciate most; it performs exactly as expected every time, handling odors and breaking down waste without any issues. My previous orders were for the smaller pouches, but since I know it works, getting the bulk pack made sense. Shipping was on par with my last order, no surprises there. It's just a dependable product from a dependable company.
Absolutely love Solbio!
Oh my goodness, Solbio is fantastic! I'd been using chemical stuff for ages, and this organic fluid is just so much better. I bought the 1.6 litre pouch for our caravan, and it's brilliant. No nasty smells, and it's biodegradable which makes me feel so much better. The shipping was super fast too, it only took 3 days to reach me. I'm telling all my friends who have motorhomes about this. I will definitely be ordering again!
Effective but shipping could improve
I purchased the 1.6 litre pouch of organic toilet fluid for our boat. The product itself is quite effective at odor control and seems gentle on the tank, which is a big plus. It's definitely better than some of the harsher chemicals I've used. However, the shipping took about 5 days to reach Denver, which felt a bit slow. It wasn't urgent, but a faster option or more accurate delivery estimate would be nice. Overall, I'm satisfied with the fluid itself.
Good value for 5 litre pack
I was looking for a more eco-friendly toilet fluid for our motorhome that wouldn't break the bank. Solbio came up in my search. I saw they had a 5 litre container which gave a decent saving compared to the smaller pouches. I also signed up for the newsletter and got a first order discount. The total cost felt reasonable for a product that's supposedly better for the environment. It felt like a smart purchase and worked well. I think I got my money's worth.
Works well, arrived fast
Ordered the concentrated toilet liquid. It arrived quickly. Product works as described for the cassette toilet. Simple to use. No complaints.
Solbio Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey guys, quick question about Solbio. I'm in Manchester, how long does shipping usually take to get here?
anyone tried the 5-liter container? how long does that actually last for a couple of people in a motorhome, like for a week-long trip?
Is Solbio actually legit for boats? Like, does it really work as well as they say in marine toilets, or is it more for caravans?
What's the return policy like if I order a big pouch and it just doesn't work out for my setup? Heard some places are super strict.
Anyone know if Solbio does a first-time buyer discount? Just signed up for the newsletter but didn't see anything right away.
