Removing Paint From Engines

Vehicle engine parts are traditionally painted with heat resistant paint, often 2 pack water based paint, which can prove very difficult to remove. Things are made worse by years of use resulting in the hot engine baking the paint on and making it almost impossible to remove. Nasty solvent based strippers containing the soon to be banned DCM (di chloro methane) make a good job of traditional engine paints but struggle with the newer water based multi pack paints.

There is a safe, water based paint remover that works particularly well on both the traditional engine paints and the newer water based multi pack systems. The product is called Biostrip. I have run tests on black painted rocker box covers from commercial diesel engines that have completed over 250,000 miles. The engines are in for refurb, and of course the old black paint needs removing prior to repainting to give that good as new look.

I immersed rocker box covers in the biostrip for around 60 minutes, took them out and washed them over with a hose. As you can see from the pictures below, every bit of paint and rubbish was removed by the biostrip, to give an absolutely pristine surface ready for repaint with no further work required.
