Getting a Clean and Shiny car on a brush wash!

 When most car wash owners wonder why they aren't getting a  great finish on the cars using their wash, they look at their equipment and more importantly their chemicals, they typically notice one thing. How foamy the soap is. If the soap is foamy then they think "Well the soap is is good so the car wash must be faulty."  But let me let you in on a little secret "THOSE FOAMY BUBBLES DO ABSOLUTELY NOTHING TO ACHIEVE A CLEAN CAR"

The foaming agents are only added for customer appeal. Here is what a good shampoo (soap) should have!

1. Alkalinine builders, this gives actual cleaning power by dissolving the dirt!

2. Lubricity. This prevents brushes wearing too soon and helps the brushes glide across the vehicles surface!

3. Wetting agents. These help the soap stick to the car and spread out on the surface.

4. Buffers. These prevent damage to sensitive parts like chrome!

5. Surfactants that keep the dirt suspended from the car to allow the particles to be washed off!

6. Fragrance, dye and foaming agents......for customer appeal!

Unfortunately many cheap chemicals do not have these key ingredients, so be vigilant and don't just seek out the foamy look! 

So to get a great clean you need your alkalinity to be titrated to about 10 drops with a good shampoo.(If your soap supplier doesn't understand this, then get a new supplier!) This is preferably applied on the first pass with mabe a 10 second dwell time to allow the chemical to attack the dirt, next your brushes will wash the vehicle with more shampoo or just a water rinse for speed. On the next pass you will brush without shampoo but will add a wax pass. I say wax but 95% of car wash waxes in Ireland contain no wax at all! So you are best suited to using a polymer sealant which won't smear up the windscreen. Play around with the dilution rates, as too much sealant is almost as bad as too little sealant when it comes too getting a good beading effect when drying. Finally one fresh water rinse pass will have the water beading off the car in large droplets. Next is the drying cycle which should be done as quickly as possible after the rinse with no dwell time! This technique is known as "Flash Drying" which uses the weight of the large droplets of a just rinsed car to dry the car faster than a car that has had a delay to allow for drip time. Now you should have clean, shiny dry cars and happy customers!

Happy car washing!
