Struggling to clean the thick greasy road crud off my rear wishbones and driveshafts before I paint them 
I gave them a liberal coating of oven cleaner foam. Left 30mins, hosed off using a brush, and they are almost spotless. It worked a treat!
I wouldn't use it near anything rubber I don't think, but maybe it will help to eat the old bushes!

It's caustic soda, also available in granule form (about £1.50 from Wilkinsons) for you to mix to whatever strength your skin/ gloves/ bucket can stand. It dissolves aluminium a treat, as I found out a few years ago whilst cleaning a gas cooker. However that knowledge has been put to good use over the years to clean up non-critical alloy parts 
It will also strip paint if you give it enough time and/or mix to a strong enough solution (but watch the fumes, of course!). It's highly exothermic and will melt plastic buckets if you get carried away 
I use Jizer in my parts washer, that eats just about anything...

I have spent the most of my working life within chemical cleaning, and 70% Sodium Hydroxide has always been delivered in I.B.C containers all off which have always been plastic and not one have melted.
Using caustic around body parts should not be detrimental to chassis other than alloys which it loves to eat.
Rubber bushes should be fine at concertation levels that could be mixed at commercial levels.
Industrial Sodium Hydroxide is even stored upto a certain percentage in rubber lined tanks, as when the concertration gets to high the correct rubber based material will cause a reaction that turns the caustic to ammonia.

Sorry Rob, seen it with my own eyes! It's not that it munched the plastic, it was the heat given off when it was mixed with water that did it...Rob
Yep your right about the thermal qualities of the dreaded caustic soda.

h of a chemical to work with to slow the thermal reaction down slowly add the caustic pearl or liquer, and wetting agent should be used and there are some wonderfull expensive ones on the market but believe me the best one yet is good old washing up liquid.
Remember being on a job years ago and we overlooked the said wetting agent so of to the local supermarket for some of the squeezy stuff worked a treat only problem was the bubbles and the client asking why the whole place stank of lemons.
