This sealant does seem better than the last type used. It blocked a thorn hole in what seemed like less than a second. The previous sealant had taken several for the same hole.

As always with Muc Off the product is top-quality and does it's job perfectly. Sealant is really easy to use too, no issues with the application through the valve.It smells and looks like strawberry milkshake, so do make sure to keep it away from kids and pets. However to Muc Off's credit they have added a childproof cap on the pouch.

New favorite sealant for higher pressure (50+ psi) tires. Works to seal punctures that other products don't when using high pressure. Allows me to use tires that have larger punctures and for longer mileage!

I have used Stan's regular for MANY years but thought I would give this a try based on positive tests.The great thing about this sealant is that it does not "dry out" like Stan's. The bad thing is that it struggles to seal even small punctures. I had one that Stan's would have sealed easily but I had to use a plug to get this stuff to deal. It seals initially but then opens up again if you ride the bike! It's not just me, a friend has had exactly the same issues and is also going back to Stan's. We both have 75% of the large bottle that will just get wasted
This stuff appears to be superior to the other brands I've used Inc Stan's (not race) Joe's and orange seal. Although I did pick up a nice big nail after the first 8 miles on fresh rubber which was obviously not going to seal, have since patched the tyre and put on a spare. For 20 odd quid you certainly get a lot for your money. And as per usual, the service, dispatch and delivery were spot on from Tredz
What wonderful stuff this sealant is, since first using some years back I've never had the hassle of having a puncture as this gem of a product sorts things out for you. Amazing how after an enduring ride you can look at your tyres and see evidence of where something has penetrated the tyre but the sealant has done it's job and without you even realising. I'm sure there are other similar products out there but my choice will always be "Muc-Off". Again another easy and hassle free transaction from my favourite online bike store.
Used the sealant with Pirelli p-zero speedcore and Mavic carbon wheels. Sealed straight away with no problems, inflating with a co2 cartridge. I’ve ridden 300 miles in the last 3 weeks with no punctures, so I’m assuming that the sealant is doing its job as the roads are in a shocking state in Shropshire!
Good quality sealant at a decent price. It’s thicker than others I’ve used and generally fixes most holes. I carry tire plugs for anything too big that the sealant can’t fix which I’ve only had to do once since using this sealant on several bikes for over a year now.
I used this to top up the same sealant used by the bike shop on my road bike tyres. It seems to work well and is thicker than the stans equivalent I used on my MTBs, with small granules.Muc-off tend to make biodegradable stuff, which I applaud.Watch out not to order inner tube sealant by mistake, as I did.
