Most car wash soaps just clean. This one cleans and leaves your paint looking like you just applied a coating — from nothing but a wash.

The Autostolz SiO2 Polymer Car Wash is our team's personal favourite and our best-selling soap — and after one wash, you'll see why. Formulated with silicon dioxide (SiO2) polymers and advanced surfactants, it bonds to your paint as you wash, delivering instant water sheeting, reduced water spots, and a deep, glossy shine that has to be seen to be believed. Especially on black cars. Especially in the sun.

We tested it on an uncoated black BMW in Christchurch — no polishing, no waxing, no coatings, no quick detailer. Just this soap, a mitt, and a bucket. The results stopped us in our tracks.

Why It's Different

• SiO2 Polymer Technology — bonds to your paint while you wash, leaving real, lasting shine and water beading with every single wash
• Instant Water Sheeting — water runs off fast, dramatically cutting drying time and reducing water spots
• High Lubrication Formula — gentle on paint, minimising the risk of fine scratches or swirl marks during the wash process
• pH Neutral — safe on all surfaces including ceramic coated, graphene coated, waxed, sealed, and uncoated paint
• Won't Strip Your Protection — existing waxes, sealants and coatings stay intact
• Concentrated — only 30–90ml per 18L bucket, so one 500ml bottle goes a very long way
• Biodegradable — safe on the environment

⚠️ Important: This Soap Is Low-Foam by Design

If you shake the bottle and it doesn't lather up like your old soap — that's completely normal, and it's actually a good sign.

The SiO2 polymers and surfactants that create the shine and water beading are chemically incompatible with heavy foam production. The more it beads, the less it foams. This is engineered, not a defect.

It will work brilliantly in a foam cannon or bucket wash — it just won't produce the thick foam you might be used to. What it will produce is a mirror-like finish that most soaps simply can't match.

If you want big, thick foam for a foam cannon: check out Autostolz Snow Foam, its the highest foaming snow foam. If you want the best shine and water beading you've ever got from a wash: this is your soap.

Directions

Shake well before use. Add 30–90ml per 18L bucket or 1L foam cannon. Wash in straight lines using a soft wash mitt or pad. Allow 5 minutes of dwell time before rinsing. Do not allow soap to dry on the surface. Use on cool surfaces only — do not apply above 30°C. Always test on a small inconspicuous area first. Do not freeze.

Customer Reviews:

Definitely does what it says putting a noticeable shine to the car once dried. - James 

"Easy to use. Good clear instructions on both products. Gives a real shine to the paintwork." - CI L

"Great Product!!! Autostolz Premium Auto Wash.  Great Product, great results and great service - what more can I say!! Will be reordering for sure!!" - Marie J.

Definitely recommend this product.  I tried this product as it was new in the Lovecars line up and at a really good price. I was not disappointed. I washed and dried 4 panels on my car using this product and the rest of the car using my usual wash and wax . The finish on the autostoltz wash was glossier, beaded water better and dried faster than my other more expensive go-to wash. I seemed to use less too. I really recommend this product and will be getting more before I run out ! Packaging looks great on my car wash shelf too!   Simon C.

That is just from a wash!  No polishing, no waxing, to coatings, no glazes, not even a quick detailer.  All we did was wash it with Autostolz premium auto wash.   We use the reef wash mit in a bucket with the mitt slide, and dried it with the rockcar performer towel, although there wasn't much to dry as a lot of the water had already sheeted off!  one quick wash and it looks like I spent hours on it.  this product really impressed me, and is my new go to, especially for black cars. No filters or tricks, photo shot on phone with wet hands as washing outside in the sun.
