I was reading the caravan club "site book" and I recall seeing that you have to use biodegradable toilet chemicals on their sites. To me that means the "green". But I have read some sites state only blue can be used as the "green" clogs up their systems.
Can somebody explain the difference and which I should use, or should I even take both ?
Thanks
