Engine Bay Open Mine Dirt

I've been trying to clean the engine bay of my 2003 Vauxhall Combo, I've been using Chemical Guy's Orange Degreaser which on the greasy bits has worked a treat but still having problems with a few bits.

On the firewall there is a fabric type material (black) which after initial cleaning looks good but as drying the chalky orange dirt can be seen again & I can't seem to get it gone for good. It's also covered some of the more delicate area's like the connectors for Fuel pump & glow plug and ingrained in with a hard sort of concrete or clay substance

Reading the forum there's a couple of products mentioned Surflex? & Autosmart Treble X

Thank you for any advice in advance

Kind Regards

I have no knowledge of the Chemical Guys cleaner but have used Surfex, which I liked. Not tried the AS product but have a vague notion this is strong stuff.

I guess you could try either products but I cannot think what would cause white residue on a firewall so I am hesitant to say brand X will fix your problem

Stay away from Autosmart Treble X the autosmart MSDS sheet lists it as a concrete cleaner.

It contains hydrocloric acid, its basically brick acid you get from the building depo and not something you should put near and engine bay.

bh surfex is a great degreaser as its quite alkaly just dont let it dry

For the fabric part of the firewall, have you tried to vac it, I use my vac with a different attachment on it a specific one for engines and arches , helps to suck to lose crap up before cleaning engine bays or arches
