Cleaning tips

Hi All,
Putting out a general question about how people go about cleaning/degreasing all the engine internals before a rebuild. Be interested to hear what process you follow and also products you use. Then once clean what assembly products would you recommend.

Back in the 1960's I had access to a Tricoethylene Tank at the garage where I worked part time - I used to put engine blocks in it and leave it over the weekend. On a Monday it looked like a brand new part fresh out of the foundry - all bare metal.
I believe health & safety have pretty much banned them due to carcinogenic issues.
On Nurse Julies 400 project posts she mentions an acid stripper I'm sure she will tell you the what & where if you PM her.

Do yourself a big favour and buy a bench mounted parts cleaning washer, £50 from Machine Mart. It has a recirculating pump (although not a filter). The part you are cleaning is held on a shelf above the main tank thereby the old dirt etc falls off the part. Don't use an old kitchen bowl filled with paraffin to clean engine parts, you'll put on more dirt than you take off!
I use Safety Clean parts cleaning fluid in mine (a mate got me a couple of gallons years ago). It does the job and when it get too dirty to use I decant it into a spray bottle and use it to clean the engine of the bike after a ride. I used to use Hyper Clean but they changed the formula and it was useless!
I let the parts air dry straight out the cleaner or where gears etc are concerned I dry them with an air line. A lot of engine cleaning fluids contain anti rust formulation.
In the majority of cases just use engine oil for reassemble (of the correct grade). I also use specific engine assembly grease for the shell bearings and silicon grease for o rings and seals.

Tricoethylene, oh my god that stuff takes me back!! In 1976/77 I worked for Racal BCC in Wembley and I sneaked out a small container of the stuff and I used it to clean off and degrease the rear rim on my 750K1, but after a few weeks I noticed it had started to rot my rear tire and skin!! ::) ;D ;D

Thanks all,
Machine mart parts washer has been ordered and I see the safety clean is there also which I may be ordering. And no Tricoethylene
