i have a hot tank with zep vat stripper in it .the zep will eat rust very bad stuff . then after that if need to be cleaned abit better then a cup wheel on a angle grinder first wet the block with Wd 40 to hold down dust .i have vap a rust in 5 gallon jug i have used .one thing about any of this stuff is when it eats the rust out you end up with pits LoW spoTs the bores and deck on rebuilds get bored and the deck gets put were it needs to by crank shaft and cam center line ..blue printed .then i base my boring bar off the new true deck . so bores or deck will clean up less very bad pitts in the bores were i have had to sleeve more then one block from bad pits in the bore. there many photos of some of the steps in my photos on here just never posted many how i do things post on here . some shops just have jet washers only they do not eat much off blocks but if you work with all new stuff them its mostly oil and grit .some shops have a bake and blast setups were they heat and then shoot the block or parts with chopped steel wire or small beads if any of this stuff fall s out on a rebuild bad thing s can happen , hot tanks.. the parts soak in the tank so many spot get clean were other way may not get it clean. bad part is getting the bad stuff hauled away $$$$.i spend more money and time in cleaning parts were you do not really recoup this in the engine building part of the game but every thing must be clean to start any work . i use hot tank .jet washer. parts washers . bead blaster . then ebow grease. not in this order but this is the stuff i may used to get things clean older or oem engines are rusty and dirty i know some machine shops send out there nasty stuff to get cleaned so you may want to ask them how they clean there stuff they may have a hot tank or bake and blast setup so you not wasting you time as your only going to get it so good and then they may want to hot tank it any way .you may want to prep the block for them smooth the casting lines/core sand .flash. stuff hanging in side and out and ruff stuff if there going to put the cam bearings in so your not grinding /sanding on the block . then your just doing the final wash when there done
