Cleaning the interior of the car is something that everyone enjoys and by and large, they want to get it over with as quickly as possible. However, it’s extremely important to keep on top of the interior, otherwise it’ll become a disgusting mess.

In this review, I’ll be taking a look at the Gtechniq I2 Tri Clean interior cleaner.

How To Use I2 Tri Clean

It’s really easy to use the product in that all you’ll need is one to two sprays onto a microfibre cloth and then use that to agitate the area that you need to clean. After that, all you need to do is use a second, clean cloth to remove any residue.

As part of the process, Gtechniq do recommend that you use their own MF1 cloths (which are great), although they are expensive but they come in a pack of 10 and can be used for a variety of applications.

It can be used on all interior surfaces of the car thanks to it being pH neutral and it won’t cause damage to the surrounding areas.


I used this on a car that had been pretty neglected inside and had a strong smell of cigarettes in it. One of the benefits of Tri Clean is that it has a smell absorber in at. This is a much better option than having a smell masker in it which wanes over time. Not only that, but it made short work of the grime that had built up on the steering wheel. Since it is the most commonly touched area of the car, it’s also the dirtiest. It returned the steering wheel to the matt black it originally was with only a few passes.

There was also some severe staining on the seatbelts as well. I2 Tri Clean did an amazing job of cleaning these and they looked as good as new.

In addition to this, I used it for some spot staining on the seats. In particular, there was some mud stains on the back of the drivers seat. After a few passes with Tri Clean, the mud was fully removed and it was left looking great.

The car really did look as though it had been professionally cleaned. There were some areas that had a lot of ingrained in dirt. Tri Clean did help to remove a fair chunk of it, but due to the severe nature of the grime in the car, the best course of action would be to clean the area first with Tri Clean. This would then need to be followed up with an extractor to remove the embedded dirt.

Value for Money

As is the case with other Gtechniq products, a little does go a long way. There are cheaper cleaners out there that have a fragrance to them, so if that’s your preference, then this isn’t for you. This doesn’t leave a smell after use.

However, unlike other cleaners, it has a antimicrobial agent within it that will destroy 99% of bacteria. This, in addition to it also being pH neutral means that you’re getting a lot of bang for your buck. It’s a gentle cleaner that has amazing cleaning power behind it.

On the neglected car mentioned above, I used a third of the bottle (it was a really dirty car) and the difference was night and day.
