I’ve waxoyled all the inside of the car and had the engine and box out and they went back in cleaned. The remaining areas that are still clogged with mud and grease is the rear axle and suspension parts so thought a good pressure wash would be in order.
It removed most of the muck and left the parts pretty clean – not perfect but a big improvement.
I was careful not to direct the pressure jet onto parts of the underneath that i had recently waxoyled but overall a very messy procedure.
