What are all these different greases used for?!

[lyralicious]

I'm trying to help Jamie by taking care of maintenance jobs on deck and keep reading conflicting information for all the different kinds of greases out there. Please can someone tell me what the specific purpose is for the following:

Teflon grease

Silicone grease

'Marine' grease

WD40

and we also have something from Turkey called Grease Spray made by Teroson (Loctite) in a spray can... no idea what I can/can't do with that. This is a chain lube.

Are there any should do and shouldn't do rules with the above?

Jobs I'm undertaking:
Plumbing for the heads (yuk)
Servicing winches (done), brakes, blocks and furling drums

Help!

The Teflon is just an additive designed to `assist` if the grease film breaks down.Silicone grease would be used if exposed to high temperatures (much higher than you would likely experience), although can be used at ambient temps.
I would expect the `marine` grease to have water resistant properties.
WD40 is just a Water Displacement material (ie WD) and can help if sprayed on various components.Not really a lubricant.
The chain lube should be what it says, designed to penetrate into links and bushes.Also should resist a certain amount of `throw off` if the chain is rotating at speed.
Hope this helps a little.Just look at operating instructions on the tin(s),should give guidance.

Silicone grease

Commonly smeared over electrical connections, eg back of switchboards, to prevent corrosion/damp.

One piece of advice I was recently given by a professional is that yotties always put far too much grease on their winches and that causes problems. He reckoned virtually every call to a dodgy yotty winch was due to over greasing. The merest smear is all you need. He reckoned.

Winches should use a waterproof marine grease on the bearings but keep it away from the ratchet pawls. Only use light oil on those or they will stick.

WD40 has almost no lubricating properties it's just a temporary water dispersant.

Grease spray is a solvent carried grease so you can spray it on e.g. a chain and it will penetrate as a thin liquid then set as a grease. Gets to the parts other greases cannot reach!

Speedseal provide silicone grease for putting on the central spindle and faces of an impeller to make it easy to remove and to lubricate against the face plate.

Marine grease is presumably for the stern gland.

Definitely keep wd40 away from plastics as it causes certain types of nylon to expand which is the opposite of what you want.

Castrol have a very educational website here

Their service support department is very good on tech questions.

+1, spot on; especially keep traditional grease away from winch ratchet pawls !
