One thing to note, use as per the bottle, if you mix it neat into the lance bottle, then it will not work properly, get the mix correct and this stuff comes out like shaving foam and sticks to the car very well, takes a good 10 mins and it is still on the car, and after washing, there are still lumps of foam on the driveway. Far more gentle than a TFR, all it does is soak into and slightly loosen the dirt, but with a coated car you do not want anything harsh, this followed by a 2 bucket wash method works very well. Review: Great stuff! - First time using this but have to say it’s really good stuff. Seen a few comments about beading and water not running off on other Gtechniq products, seriously, do people think the rain will dodge their cars after applying? It’s good but not that good!! ## Features - Causes serious eye damage. - Causes serious eye irritation. - Causes skin irritation. - USE BEFORE CAR WASHING TO LOOSEN DIRT - apply to paint and let the thick foaming agents and degreaser lift off stubborn dirt and road grime to make car washing much safer, easier and quicker. - BIODEGRADABLE, NON-TOXIC AND NON-ACIDIC – not only is the gentle yet effective formula harmless to the environment.

It’s good but not that good!! ### ⭐⭐⭐⭐ Good stuff - doesn't foam as much as I expected *by R***G on 1 August 2024* Followed all the instructions and can get a reasonable foam but not a really thick coating as maybe I expected. Quality product though and does bring the car up really well so will certainly buy again. ## Frequently Bought Together - Gtechniq - W4 Citrus Foam - High Content Foaming Agent, Removes Dirt and Road Grime, Non-Caustic Formula, Maximum Gloss Retention Snow Foam (1 Liter) - Gtechniq W6 Iron and General Fallout Remover for Cars, Brake Dust Degreaser and Cleaner for Wheels, Rims and Paintwork, Safe on Coatings, 500ml - Gtechniq - W1 GWash - High Foam Content, Maximum Gloss Retention, Tough On Dirt and Grime, High Slickness Lubrication - Breaks Down Residue, Works Great in Foam Cannons (500 milliliters) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/52327554-w4-citrus-pre-wash-foam](https://www.desertcart.co.th/products/52327554-w4-citrus-pre-wash-foam) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
