Problems with a smell from the Thetford seem to be a very personal matter. By that I mean that everyone seems to have a different tolerance level for unpleasant smells. Personally, I never notice it.
If we are just stopping for a night or two I use the Thetford chemicals, (the whole bottle) with formaldehyde. I understand that there is a biodegradable type as well. If we are staying longer I have the toilet tablets and throw in one a day to get even more bacteria killing solution.
That works for us.
