This degreaser works fine though my last cleaning I had to clean twice to get it squeaky clean - may have rushed the job. Decent odor, no residue on concrete after. Issue is the spray bottle - it is terrible and sticks constantly. I respect the Muc-Off brand but the company needs to upgrade its spray bottle for this. Very aggravating when your are cleaning and have to operate the spray bottle with two hands.
I have been using dry lubes for many years. I am certainly in the minority of riders and wrenches I know who likes Pedro's Ice wax (the original formula was is superior to the latest generation). Wax based lubes work well in dry conditions, particularly when one services their bike regularly as one should. I've used Muc-Off's Hydro dynamic lube and liked it's overall performance so I gave Bio Dry Lube a try. My immediate first impression was the smoothness and how quiet the drive train was. I would recommend this lube to anyone who rides in dry conditions which of course we all prefer to unless of course it's cross season.
I initially used R&R but my LBS talked me into trying another brand. The other stuff gummed up and got dirty a lot more and my rear cassette started showing signs of rust. I went back to R&R recently and could tell a difference. Not as gummy and easier to clean.
