Using the Kärcher FJ6 Foam Jet Nozzle with Meguiars Gold Car Wash – I wasn’t sure how good the Kärcher FJ6 Foam Jet Nozzle would be when I bought it. All the American ones I’d seen on YouTube where huge, but this performs perfectly. The 0.6l capacity is fine, it will literally burn through the contents and by the time it does the car will be covered in suds. If you use Meguiars Gold Car Wash neat with the Kärcher FJ6 Foam Jet Nozzle the results are impressive. There’s a valve at the top which you can use to reduce flow (never used it) and the nozzle itself can swivel 180 degrees. Again never used it.
Just plug and spray and get your car super clean. I usually jet wash the worst off first, then follow with Meguiars Gold Car Wash suds, then wipe with a woolly car cleaning glove dowsed in cold water (in one direction) with many bucket changes. If the water looks even a little dirty – get fresh water. You can get massive buckets for this – but I’m currently using a small one as I’m in and out of the kitchen.
