Harpic Blue

Just something I spotted on another site, anyone tried it? looks good! could there be any damage? I wonder if it work on spokes an stuff? if there was no damage?

Copied & Pasted..



So been spreading this tip around as it's so great! The headers on my Bandit were pretty bad, covered in spots of tar and very discoloured! Got some harpic blue toilet cleaner, wiped it on, left it 5 mins and wiped off and they came up like new! Saves hours of autosol and polishing! Can't take responsibility of this tip as it came off a forum but a good one none the less!
Before


After

Looks clean round the bend to me ! 

Where did ya find it Sim .... You-Tube ..... or U-Bend ?

I suppose its worth a try though ..... but what will the missus say when you sneak off to the garage with a bottle of Harpic

Yam it's an acid cleaner so that's why it comes up looking reasonably good after a soak in it.
My dad used to get acid degreaser for me when he was working that they put on loo floors etc to get stubborn stains off & it worked a treat on my old bikes as long as you ensured that you washed it off very well!

Yes, I suspected it might be an aggressive form of cleaner, & not surprised in needs 'washing off' afterwards.

One thing I've used on tar spots, or 'boot marks' for a few years on chrome exhausts is normal car wax.
If applied whilst the exhaust is hot it will remove the marks - a bit of elbow grease is required - but it does work. If the wax dries out, you have to apply a bit more, until the stain has gone - but it is non-aggressive and polishes at the same time ! ...... BUT you need to be aware of the obvious H&S issue - it is a hot exhaust , & you could get burned ! I fold a soft cotton rag over several times - but you will feel the heat coming through the rag ..... I suppose you could wear an old pair of leather gloves to save your pinkies.

good tip Sim like it guessing it would work really well for those that have spoked wheels as well

Seems good stuff.

I wonder if it could be too corrosive if there was overspill onto any alloy parts? But I'm not a scientist so I've no idea really!

Not flushed with success then Mal ?  

Stop pulling my chain

U-bend-ing my ear again !

Wassup Mal going round the bend???

I reckon I may try that stuff, just need to remember to hose the bike down properly after. Dont want to come out in the morning and find my bike has evapourated but looks worth a punt

A handy thing to use but with a lot of caution needed.
