Chief, ive been washing my own and my friends and family’s vehicles for many years. With just a hose. The fact that i do it regularly allows for the force( if one could call it that ) is sufficient to remove the soiling. That combined with todays chemicals such as Primus or BH Touchless make cleaning much easier. The same goes for cleaning wheels which tend to need sttonger chemicals of which there are many choices.Maybe because i was washing before pressure washers became so prevalent makes one not as necessary. But i have zero issues getting my vehicles clean with just a good hose system such as my Eley. The key is getting good flow and pressure.
Different strokes for different folks.
Indeed different S for F. I don't use prewash chems unless I have a genuine use case. I prefer to minimize the effects of LSP. For my use case, LSP doesn't last as long on PPF, so the more neutral the wash, the better.
I do use pre-wash for every wash during the winter. Beyond the winter season, I only use it if I feel like a plain Jane H20 HP pre-wash is not going to cut it it and needs a chemical bite. Same with wheels. I tend to use shampoo and let PW do the work.
Are your running a Eley Hose in your -Eley System-.
If you are running a eley hose, that hose is 5/8"
For LP, I prefer 3/4 hose. It's noticeable in both flow and volume.
If you're running a Eley hose, try a 3/4, including the leader hose to the reel
I think a pressure washer speeds things up. But setup time takes away from that efficiency gain. Blasting off the surface does buy you a little more margin to be sloppy with wash media. I used a pressure washer for a couple of decades. New house, I haven't set it up to be quick, but I will eventually get around to it someday....I hope.
I'm faster and I'm slower with a PW....
For the main panels, I'm faster as I can contact wash faster as the HP rinse has gotten most of the stuff I need to be careful with if I was just doing a LP wash
With a low pressure wash, I'll jab the ez detail around the wheel wells and call it good. I'm not too keen on scrubbing said area as I'm getting lazy.
But with the HP, I end up feeling like I'm a dental hygenist.
1st HP rinse is with a wand just to get the majority off.
Then I switch to just a nozzle tip and gun, as it's easier to control and get the wheel wells super clean because I can now manage the gun at a closer range and *angle the curvature-sweep* as I high pressure rinse it out.
I ultimately spend more time doing WW cleaning with a HP PW as it's a different POV on task to clean
