any decent tar remover on the market

[Bass]

There's a commercial cleaner called Desolvit (or something similar). It's not often in the supermarket but places like Mitre 10 stock it - clear spray bottle, orange label. It works like kero or turps but its water emulsifiable. Just hose it away when it's done the job.
It works wonders on fresh tar on a hot muffler - just runs away. Old, baked on tar with all the volatiles gone is a different proposition no matter what the cleaner.
I've tried all the others suggested except peanut butter. They all do about the same job but the stuff I have named is just heaps faster because of the "hose it" clean up. It's a household cleaner so has heaps of other uses too, like getting rid of chewing gum.

I run a Scott oilers on both bikes and so the front sprockets chuck a fair bit around the "hard to get at places" on the gearbox and crankcase - especially the DR cos I put plenty of oil on the chain to flush the crud away. Cleaning time = spray this stuff around, stir it up a bit and put the hose in. Presto!
I notice that all the bikers I have mentioned it to, who have actually tried it, now have a bottle on their shelf.

One note however - the work area has to be dry. As I said, it emulsifies with water and once that happens, it won't clean anything.

I use Amway Gel Bug & Tar remover. It's an aerosol.
Just spray it on, leave it for a couple of minutes and hose it off.
A couple of weeks ago I had the misfortune of coming across some bleeding tar on the road. It was so runny it was all over the outside of the front guard, motor, zorst, and tank.
One good spray and it all ran off.
I'm just about to order another can.

I was about to recommend this stuff. I had some years ago and wasn't sure it was still available but it's great. Doesn't stink either and it's really easy to use.

That needs to be softened up first, using heat and/or solvents, then the bulk scraped off with a plastic scraper (provided it's not on paint), then the residue can be dealt to with whatever is the tar remover of choice.

Thanks Guys
I did the CRC / Kero thing this weekend on the alloy wheels and it was brilliant.
Desolvit is more of a glue remover for sticky labels. I have some so I will try it next time.

Either use your tongue or some spit...rub on hand rub on wheel

Once you done that, use some Black Knight wheel cleaner from Supercheap on it, great stuff!

Wurth brake cleaner is brilliant for removing tar and other things as well. Doesn't harm paint or plastic. Just spray some on a soft cloth and the tar just wipes off. It also evaporates completely.
You need to re-apply wax afterwards if its a painted surface because obviously it removes the wax too

Yeah butter really does work...old wives remedy....Ok....how do you clean the butter off....with a piece of bread of course... (just kiddn on the last part!)

Be careful with De-solv it...its for removing stickers and adhesive residue....it will start to lift vynil trim if its not clear-coated over. But it is bloody good stuff.
