Review (4/5): Clean & lube your blades while running
I am not a beautician or barber, just someone with 2 dogs needing regular clipping. I remember seeing this product or a similar one in barbershops where my Dad would go to get a haircut. It was in a good-sized flatish round jar and the barber would dip the tip and bottom of his clippers in it while running and they would come out shiny and hair free. Now the jar looked like a pot of disease waiting to get passed on to the next customer as it had floating bits of hair and residue from who knows what.
I had been cleaning and oiling my clipper blades after each grooming and using a coolant on them during clipping to keep the blade's surface from getting too hot. Cleaning the blades afterwards never seemed to get all the hair from between the teeth even using a tooth brush and sliding the two blades back and forth. This stuff really CLEANS all the hair off and you can hear that the blades are better lubricated by the reduced noise. I do wipe them quickly so as not to drip any of the H42 onto the dog. They are shining and humming pleasantly after dipping them into this stuff. I will continue to buy this product as I feel it will extend the life of my clippers and make for a better cutting blade.
Now for the down side and why I took off one star. This stuff still comes in the good sized flatish round "tub-like" container and is seems intended that you dip the blades (not the motor, just the blade tips and bottom) into the whole container full and continue to reuse this stuff over multiple cuts. I don't care if it is Virucidal and Anti-bacterial, that seems like a really unclean way to use this. I solve this problem by pouring a small amount into another container (at least 1/4 inch deep) and dip my clippers in that. I discard the stuff after each groom. Unfortunately the container it comes in does not pour without dripping and yes, you use more of this stuff using my method. I continue to use oil and coolant, but this stuff truly cleans off the bits that get between the teeth and seems to get the blades running much smoother. I do recommend this product, but not for using the reservoir full repeatedly over several cuts or clippings. That method just doesn't sound like a healthy way to go. So if you use clippers on humans or dogs, I feel this product may be of use to you.
