Dr Downpipe Motorcycle Exhaust Downpipe Cleaner - 500ML Spray Bottle

Great cleaner does what it says

I was a little sceptical about the apparent magical qualities of this stuff, especially I've been using a combo of diluted Harpic & Autosol for ages.. however Dr Drainpipe really is that good. Couple of sprays, agitated a little with a scourer then spray a little more.Almost zero elbow grease required, took about five minutes to get my 10yr old downpipes looking pretty much brand new.

Worked well on my 3 year old and limited mileage Triumph downpipes; but like a numpty I didn't wear protective gloves - my hands didn't thank me for many days afterwards!

If I shown the before you would not expect the outcome. It is an excellent cleaning product, no effort at all the ingrained dirt hit the dust as soon as it was applied.

Had high hopes for this product due to its claims but didn’t hold up. Honestly my motorbike exhaust wasn’t in great condition to start but claimed with multiply uses it would clean up. After 5 coats with agitating between each coat with provided scrubber it’s wasn’t any better. Granted it brought off some dark colour but wouldn’t pay the money for it. This product probably suits more to someone who has very slightly discoloured exhaust and wants to bring back a little shine. I personally wouldn’t buy again

Don’t use 10x Harpic which WILL corrode your metal - Dr Downpipe has the correct formulation ! It’s not instant but follow the instructions and apply some effort and this keeps your downpipes and cat very clean indeed. Not cheap but worth the investment if you want to do the job properly. Highly recommended.

Very good

Cleans wonderfully with minimal effort, I sprayed it on my exhaust scrubbed a little and it came up beautifully. Thank you!
