Optiglanz stainless steel cleaner, £11.99
Miles covered/time: Used once a year to repair winter damage
What’s good? I asked the guy at my local Hein Gericke if they had anything to clean downpipes and he recommended this stuff from Optiglanz.
All you do is give the pipes a good scrub to remove loose dirt, spray it on, leave five minutes then rinse off.
I was amazed at the results. For a like-new finish you’ll have to break out the metal polish afterwards like I did, but this spray will remove the bulk of the discolouration as if by magic.
What’s not? It’s pretty evil stuff so be careful – it causes cauterisations, so buy some rubber gloves. Other than that £11.99 is not a lot to pay for shiny down pipes.
