Chemtech CT18 Superwash 20 L
Chemtech CT18 Superwash 20L When your vehicle wears the week’s dirt, red dust and oily road film, you want a wash that simply cuts through it. Chemtech CT18 Superwash 20L is a serious, multi-purpose cleaner made for tough Australian conditions. It quickly breaks down baked-on grease, grime, soot, bugs and oil so you rinse away a streak-free finish, not elbow grease. The pH neutral formula is gentle on modern paint, clear coats, wraps and alloys, yet it gets deep into crevices to help inhibit rust and corrosion-ideal after beach runs, wet worksites or muddy tracks. Your vehicle gets that fresh, bright look without stripping protection. Versatile and economical, this concentrated wash cleans most washable surfaces-paint, glass, plastics, rubber, vinyl and metal-across cars, 4WDs, utes, trucks, bikes, boats and caravans, plus gear like windows, building exteriors and marine equipment. Use it your way with a bucket and sponge, a foam cannon or a pressure washer, and dial in the dilution from quick maintenance cleans to heavy-duty degreasing. It’s biodegradable with low toxicity, so it’s the practical choice around home or the workshop when used as directed. Proudly Australian Made, CT18 Superwash delivers the reliable results you expect-leaving your vehicle clean, streak-free and ready for the next run.

Brilliant product that I have been using for years with great results. Used for: 1.Cleaning exterior of our home and windows with streak free results on glass. 2. Motor vehicles 3. Caravan 4. Rural Fire Brigade Appliances. Tips: 1. I use only TANK water as it does not contain any additives that are likely to leave residues on the surface and spots on glass. 2. I apply the product with Snow Foam cannon 3. Dilute the product when adding the Snow Foam 2 parts TANK water to 1 part CT18 4. When washing vehicles I still use a chamois and microfibre cloth to creat a brilliant finish and every 3rd wash I add 1 cap-full of CarLack68 Classic to the Snow cannon mix. This makes and excellent wash n wax.

It’s the best of the best, used it for 20 years tried other truck washes and none come close. Use it on cars, motorbikes, mountain bikes. I’ve left it for days soaking after spraying carbon fibre mountain bikes even my Harley and dirt bikes without any damage just a very clean end result.

I have been using this product for many years and have found it to do an excellent job keeping our vehicles clean. My wife also uses it on the bathroom shower and also in the washing machine. I also use to wash the house, firstly spraying onto windows and paintwork , leaving for a few hours then rinse off with hose or a pressure cleaner. A very versatile product. The longer you leave CT18 to dry the better it works...

Although this is sold as a truck / car washing detergent, it is great for many other cleaning purposes. I use it for window and shower cleaning. Its ability to be applied and allowed to penetrate grime for up to twenty four hours makes it clean exceptionally well. I have used to to wash the brick walls of the house as well.
Quick and easy purchase, ripper special, great product. Apply to car, gerni car, quick sponge here and there, rinse and done. Best wash product I’ve used thus far.
I have used this for twenty years. Nothing gets off dirt n grime like C18 truckwash. Leaves car shiny n clean like new, does wheels n rims great as well. Highly reccomended. Bargain pricing. Will last my three cars forever. I use with hot watwr n its works best first time everytime.
This stuff works freat for my use of washing 3 cars with my Karcher and its power washing kit. On half price sale was a LOT cheaper than the blue goo from Karcher. Smells nice and works well. Thick consistency, pours fine from a tap.
I have used this brand of vehicle wash for several years because it is pH neutral and therefore safe to wash my aluminium boat with. It also just happens to be a great car wash generally because I never really notice any streaking after I hose it off. I use a long handled soft vehicle washing brush from Bunnings to dip into a bucket of water with a bit of this detergent in it to wash two cars, my ute and my boat very easily and quickly with this stuff. ie I never bother using a chamois to dry off the surfaces after hosing the detergent off as it does not seem to be needed.Normally, I buy it in a small bottle but when Supercheap had a weekend special on the big drum of this stuff, the value for money was so far ahead of buying it by the smaller bottle that I just ...

However, Bunnings sell the right sized plastic tap for just $1.98 so fitting one is no big deal. (Be aware that these same taps are sold elsewhere at ridiculous prices so it is best to get them from Bunnings.)Highly recommend as a vehicle and boat wash. this is good stuff.I bought this by "Click and Collect" from Supercheap and that process was brilliant. The heavy drum was ready for me at the front of the store so that I did not have to carry it too far to my car. The sales assistant offered a trolley but it was ok to carry a short distance for a big brute like me.
Chemtech make some great products, and CT18 is no exception.But when you have a 20L container with a useless thread for the tap - you may as well throw $120 in the air.Big issue that needs fixing!
I was introduced to ChemtechCT18 some 25 years ago for washing my boat and 4WD.It is so good I always buy the 20 litre drum, and mix it 50ml to 1 litre of water and apply with a hand pump sprayer on my vehicles mostly, but have done pavement as well. Our car has a duco protector, so CT18 being ph modified all has been Ok. The car still has a showroom shine, and has never been polished in 15 years.cheers,Brian
