The original Thetford formaldehyde formula is still the best.

That is exactly what I'm using right now as I sit in 90+ degree weather in Joplin. Why do I use formaldehyde? Because it flat out works that's why. There must be a reason that 99 out of 100 embalmers put formaldehyde in there RV toilets. :B
Me too. I do also have some of the weaker formaldehyde free stuff for the grey tank ame also for short use in the black tank or use in cooler weather, but for longer term usage or for use in hot weather the Thetford blue stuff with formaldehyde works best.
