Questions about STRIPING FROM SURFACE CLEANER. Driving me nuts

OK I am with you on the olive or date stains, but I tried the bleach afterward and it didn't do anything, just can't win with those.

Try a light coat of Oxalic or F9, I bet that will take it out.
 
Use straight SH from a trigger or pump sprayer. Just hit it and let it dry for a few minutes. It matters how strong the mix is and how long you let it dwell for these type stains. Plant and tree stains.

In Houston we will prove the rights and wrongs of this.

Tips are the real issue


Oct event San Diego free free text me for more details !!

1. When are you coming to Houston?
2. At 3000psi/4gpm, 100-150' hose and a 20" sc with a 2 tip spray bar, I'm going with 25025 tips

Of course this came from research and recommendation from all the vets and dealers.

I'd love for someone to post the formula!!! (ex. psi/gpm x ft of hose = what you should divide the number of tips your sc has)

This sounds like it will be a huge event and I am sure I will be there.

Anything on the agenda yet?

Here is a chart. Pressure drops about 100 psi per 100 ft of hose.

I've seen this chart - it's so confusing. When it comes to surface cleaners, I guess you divide some number by the number of tips your sc has. Mine has 2.

How does one come up with 25025 from this chart???

1. Why 25 degrees vs 0, 15 or 40?
2. 25025 or 25025

So, in theory, the perfect tip for 3000psi/4gpm would be .056/2=.028, which don't exsist, thus 25 degree .025 (x2)

Am I right?
 
CL you read the chart right. For your pump the proper orifice for full pressure on a wand with one nozzle is #5. Divided by two for a two nozzel surface cleaner is 2.5.
Nozzle numbers always start with the fan pattern being the first two digits. The the last two or three digits are the orifice. If there is three digits the last digit is the number after the decimal point. They don't put decimal points on the number. A 15025 tip is 15 degree fan and a #2.5 orifice. 25025 is 25 fan and #2.5 orifice. I used to run 1504s on my 8gpm unit but have been more happy with 2504s as far as less striping results. I am now expermenting with 40 degree tips on less stained concrete and am happy with results. Hopefully soon I'll get a heavily mildewed molded concrete to try it on. I cleaned probably the worst concrete I ever cleaned last week but that was with 25s before I had the 40 degree tips.
 
Dirtiest concrete I've cleaned as far as mold / mildew. After pics not great because of harsh sun and shadows but it looked new. Pre and post treated with housewash mix.

I am sooo happy right now. I got it. I even understand the rest of your post! Just for fun, the next time I order something, I'm going to throw in 2 - 40025s. Thanks Pat!
 
Great job on the dirty concrete Pat, turned out good.
 
Even though you had a breakdown, they should be very happy with the end result.

That driveway would be a good test for my new surface cleaner that will be ready in a month or less, over 50" cleaning path but shaped different.
