Dick Rutkowski, the "father of EANx for sport diving" is of the opinion that tanks and regs need not be O2 cleaned for mixes up to 40%. But he's in Florida and most of the Florida fill stations blend the Nitrox before filling tanks. Out here, O2 is pumped in first, then topped with 21%. That makes it mandatory that the bottles be O2 scrubbed. You've got no choice out here, guys.
