It is tough to find out the dilution ratio, because you will need to confirm the water flow rate first, then measure how much shampoo it uses per time (seconds or minutes).
If you are using 'per minute', measure how much water goes through your PW by firing it at a bucket and stop once you hit one minute. Do the same for the shampoo also.
Hmm, come to think of it, might as well fill up a bucket with the water/shampoo mix for a minute and measure the shampoo/water mix and the amount of shampoo used. I hope it is not confusing
I use the standard 'shampoo dispenser' I have and it won't foam much, but it is still alright because at least some shampoo is on the paintwork and it starts to emulsify dirt and grime.
Thanks for the idea dude.
Now am searching the net for dilution rate oz per gallon or ml per l vs this dilution using shampoo dispenser that comes with the power wash. The 'per minute' flow mix of shampoo n water kind of makes sense. But wait, but what i really want to know is how many ml or oz of shampoo for how many liters of water. Thinking of variants of the bucket per minute calculations for this. Maybe ken has some ideas on this.
As in how much water per minute for a bucket.
How much shampoo per minute for a bucket.
How much shampoo and water per minute for a bucket.
The bucket will have the gallon marks too. then the flow rate can be gallons per minute. or liters per minute.
Just gotta figure out how to relate this to the traditional wash bucket system dilution of oz/gallon or ml/liter.
It's easy when you know how...
