Lanolin grease

[[70521]]

Anyone tried lanolin grease such as Lanoshield (I've seen advertised but not used) for protecting prop and shaft to reduce fouling? Any good or don't bother?

Only useful if applied every 24 hours.

As a child my late mother, a Registered General Nurse, would give me a ball of butter rolled in sugar when I had a cold. Before she died I asked her why, as clearly butter in sugar has no medicinal benefit. Her reply was interesting, 'because my parents did it with me', in other words an old wives tale that had gone unchallenged.

If there are any pharmacists on the forum who could give a scientific explanation to support the 'butter and sugar medication' I would be interested to hear the science.

P.S. as a child I hated school milk and as for butter ugh.

My mother used to put butter on our burns and bruises.

I don't suppose it made any difference, apart from the placebo effect

Twin screw motor boat, I applied it to one shaft prop and rudder, followed the instructions to the letter, heated up prop etc to dry it.
I then forgot which side I used it on.
At the end of the season you could not see any difference with one over the other, a waste of time and money and elbow grease.

I have used udder grease for cows which I think contains lanolin I believe. I am in a tidal esturary. I have been putting it on the prop for over ten years .My boat is a sailing boat and I use the engine for about 140 hours per year. I have a scum at the end of the season (October) and boat stays ashore till April.

I polish my prop before launch then about every 4 to 6 weeks wipe the slime off the hull using our hookah. (We do have the advantage of sea water temperature of 26degC at the moment.) At the same time I use a stainless steel pan scrub and shine the prop. No barnacles and no nasty paints used

I find a thorough polish before launch and a good scrub in July keeps er right...and a bit if use...

I have successfully used raw lanolin for the past eight years on my prop. I apply it as Davidmh described. After two years I have minimal growth that comes off with a light sand. Warm it in the container until it is sticky and put it onto the warm prop. In Australia the sun is an adequate heat source or use a hair dryer - keep it away from clothes. It is also very good for protecting electrical connections.
