does the boot mat come completely out of the car?
Think so mate. Doesnt look fixed in any way, jus pulls up
Fully removable
right... in which case beg, borrow or steal a pressure washer... find a stiff brush (a nail brush is ideal) and get yourself some degreaser (such as megs degreaser or autosmart G101)..
pull the carpet out... liberally spray the carpet with a dilution mix (according to the instructions on the container) of the degreaser... leave it to soak in for a wee while and then work it really hard into the material using the nail brush... leave it to soak a little more but do not let it dry out
grab the pressure washer and methodically work your way, a section at a time, over the carpet and wash the gunk out of it... make sure you have thoroughly rinsed all the degreaser out of it
if you have an extraction machine, like a vax, which can hoover up water then now is the time to use it
if not.. hang your carpet up on the line if it is a sunny day or in the garage and leave to dry... make sure it is dry before you put it back in your car.
