Chassis numbers

I have a morris c8 with the chassis number stamped in the spring hanger. Due to corrosion the centre digits are hard to read is there any way  of enhancing them

I'm seeing 228330x  Not sure about the x as the focus is off on the right side.

Try brushing some white vinegar on for 2 or 3 days - try & keep it wet , this should dissolve the rust away. It will not harm the steel so you have nothing to loose.  Then wire brush off the black remains of rust  and rub white chalk in , then rub off the residue., it should highlight the numerals.
