Hello, while chasing a water leak in my 91 corvette ive decided its time for a general engine cleaning. What is the safest to use for light grease and that will rinse off with a garden hose? Looking at detailers pride products. Already have a great assortment of bruses of all lengths, sizes etc.

Check out Amazing Roll-Off. I here it's works well. I bought some but have not had the chance to use it yet.
 
If you opened my hood, all you would see is plastic covers! So I use Meguiar's Engine Cleaner which is safe for plastics and rubber. And no nasty odor. That works for my needs, since most of the covered engine components don't get dirty.
 
I use Meg's APC+, has yet to fail me. After I use 303 on all plastic and rubber.

I use p21s and a boars hair brush. I rinse off w a gentle shower and walla. Does an excellent job.
 
Meguiar's All Purpose Cleaner or Meguiar's Super Degreaser for the tough stuff. I also have a variety cleaning brushes to loosen and scrub areas for a thorough job..
 
Amazing Roll Off. Diluted and a garden sprayer, brushes and terry cloths. It seems to leave a nice sheen on things also which is a plus in this case.

Do you guys just wipe down the surfaces with a wet microfiber/APC or do you use a scrub brush on the bigger plastic pieces?

I ask because I usually just wipe down the larger plastic pieces with apc and damp microfiber and I know it probably does not get off all the old dressings. Maybe a scrub brush might be better to remove old dressings?

Although I know it is impossible to use a brush on ever little wire/tube/hose. But maybe just the bigger pieces of trim coverings.
 
simple green and purple power are great and strong and can be found nearly everywhere (home depot, autozone, etc)
 
they even make a simple green for automotive use- wont deteriorate rubber surfaces.

The problem that simple green has/had is that if you did not flush with water completely it would etch/eat aluminum parts. Unless they changed something that would still be the case. I use to use it but for that reason only I switched to ARO. I never had any problem but a lot of people did and I was not taking any chances.

Simple Green products are all acid/chlorine free so they shouldn't be able to etc metal. You shouldn't let any cleaner dry on bare metal nor use any cleaner on hot surfaces. I think the people that say SG etched their metal parts are leaving out some variables. I just used some old stock SG engine degreaser on a friend's diesel, Jeep Liberty(CRD) and it did no damage. I also tested it by soaking some pennies overnight in the degreaser and the only thing I noticed adverse was some pennies that had gouges in the had some white aluminum oxide on them. But no damage to the copper coating. That said most APCs and degreasers aren't meant to be used on bare aluminum.
I usually use SG ProHD or OPC.

I just use Simple Green. It works fine for my needs.
 
Simple green will sometimes react with aluminum or some metals even if you don't let it dry. I usually just clean the part up after with a little never dull. I did the engine on a jeep Cherokee with it yesterday and then finished it with PERL and it looks awesome!
 
I'm with everyone else here, APC+ is my go to, followed by some variety of Purple Power or Simple Green. (the last 2 are always on sale somewhere)

Even my wife has started grabbing my different mixes of APC+ for household messes! :rolleyes:
