Greetings. I am posting this thread to see what some of you think are the pros and cons are when two-stepping or brushing. When do you feel it is best to use either or?
Some trucks are great for 2-stepping where some are better for brushing and some you have to do both, there is not really a 1-method does all greatly, just depends on your customer's expectations.
There are some truck and trailers that come out great when 2-stepping and you don't need to pick up a brush.
There are some trucks/trailers that have been neglected that for a higher-level of quality service it is a good idea to use a brush sometimes, it really depends on the job and what quality level you offer.
I have an account where I use hot water and soap injection and still brush as the high pressure soap will not remove everything and the level of quality I offer needs a brush most of the time, sometimes it gets real clean without brushing but not all the time.
There are great systems like the Bioclean that gets trucks very clean and not needing brushing, there are systems where you run the soap/brightener through the pump, there is downstreaming, etc.....just depends on what you are looking for, what your accounts want and what you want to offer.
Ive got a video you should check out. Its on here somewhere and the www.fleetwashacademy.com listed under videos
One company we clean owns around 200 trucks. They buy about half new and are always buying used trucks. I can tell which ones have been 2 stepped cause of the dull paint. IMO the acid (if used too strong) will dull the paint.
Another company we clean for only has 20 trucks. They had been cleaned by the same company for 4 years before us and that company 2 stepped always. The trucks were dull with no shine when we took over. In the last 5 years, this same company has bought 5 new trucks and we are the only company that has cleaned them. I use my detergent (single step) fairly strong and only brush them maybe every 4th or 5th cleaning and these trucks (with exception of scratches, etc. from use) still shine like they did new! Same Freightliner trucks as the dull ones. We have some trucks we have cleaned this way for over 10 years and they still shine and some that were dull 10 years ago and are still dull. Now I don't know that ALL the dull trucks we cleaned were 2 stepped, but most I do know were cleaned that way. Maybe the guys that cleaned them just aren't doing something right, but the trucks are dull!
Maybe it was the soap the others used that dulled the trucks in combination with the acid, but I use a very strong detergent (its strong enough to clean an engine with warm water in the winter)
On regular cleanings (weekly for the most part), we use 2 8gpm machines. One downstreams soap and other rinses. When the soap guy gets a few trucks ahead, he changes tips and rinses to let the other guy catch up. We can usually clean 10 -20 trucks per hour this way. We go back before moving the truck and brighten tanks and wheels the same way.
I do 2 step van trailers when they are bad, but all the ones that we have are older trailers and were dull when we started cleaning them.
Now I am not knocking anyones method, but that is just my experience. These dull trucks may be just results of a hack contractor, and not the fault of the acid used but I am not cleaning that way because of it. Also a single step with even some brushing is faster for me, maybe not everyone but for us it is.
We only clean 75-100 trucks/trailers per week. I could get a lot more to clean, but we do these and start Friday morning and only work till noon Saturday. Years ago, I would work all weekend but now with 3 kids I like to get most of my weekend off!! Also April- Oct. around here is race season (dirt stock cars) and my oldest son and I both race LOL
