IRON OX­IDE & AD­HE­SIVE RESIDUE

- Belarus · Austria

1 The paint­work on our Alfa GT isn’t too bad for a 15-year-old car. After a thor­ough wash, we no­ticed sev­eral blobs of dried residue (pos­si­bly ad­he­sive) on the bon­net, so we applied a little white spirit to soften and pick them off.

2 All the residue was suc­cess­fully re­moved (it also helped to leave the Alfa in the sun­light to warm up the body), then we applied a pol­ish and buffed it by hand.

3 The al­loys are in rea­son­able con­di­tion, but had lots of in­grained dirt, so we de­cided to try a wheel clean­ing mousse from Au­to­glym. First, they were washed and rinsed.

4 The mousse was then sprayed over one wheel at a time, work­ing from the bot­tom up­wards. A foam quickly formed and we left this to do its work for a few min­utes.

5 The in­struc­tions on the aerosol can of mousse rec­om­mended ag­i­tat­ing the foam with a brush, so we used an old brush that came with a wheel-clean­ing kit.

6 Within a minute or two, red/pink residue ap­peared. This in­di­cates the pres­ence of iron ox­ide de­posits, usu­ally from the brakes, but also from air pol­lu­tion and other ve­hi­cles. We then rinsed the wheel.

7 The clean­ing mousse can be applied again if re­quired or, if there are some stub­born de­posits, a more ag­gres­sive cleaner can be used. For now, this quick method of clean­ing the wheels was suf­fi­cient.
