Yes that is in the range that it is supposed to be. I have one that starts to spit it out if it gets too high.

yes, there should be a red dot in the middle of the glass.

I use it to supplement my fuel right now, it is too cold to use 100% bio because it gets thick when the temps drop.

I have to agree, it is not worth saving a few $$ to try and make your own mix on somebeody elses house.

I have used it on some cleanings. NaOH in strength can strip paint so you have to be careful. It is more effective on dirt and road grime that bleach won't touch.

For a rinse aid some put in Jet dry dishwasher rinsing aid to helpwith window streaks. Doesn't take too much and works form what I understand. Car wash soap w/wax works but is pretty costly to add enough to make it work very well.

Mold and algae are 2 different things. Most residential type mold is black while algae is green. They both however are cleaned with the same thing-chlorine bleach. The black streaks on gutters are cleaned with a butyl based degreaser and is brushed on then rinsed off. Oil spots are treated with degreasers as well, just spot treat the stains. You will lighten it but most likely not remove all of it as concrete is porous. Rust is oxalic acid, although you will most likely have to treat the entire area to achieve a uniform look. Tire marks may come off with just the surface cleaner. Do a search on here of pavers. I remember some posts in the past and they had before and after pics as well. You need to investigate the pavers closely, be sure they are solid color all the way through. You will also want to do a test spot with the products before you actually spray them all over. You don't want to change the look of them by removing too much color or surface.

I can get 15% but that is it. It is strong and unstable and the gas can be very hazardous.

Bleach is the common name given to chlorine. The 12% is the concentration of it in water. 12% is almost the stongest you can get, the common Clorox brand bleach is around 5-6%. The chemical compound name is NaHClO3. You can only purchase the 12% from pool suppliers and chem companies. Oxalic is an acid that you would not want to use to clean a house. Most of your house washes would be to clean mold and mildew and bleach/chlorine is what that is good for. The reason you would want to purchase 12% is when you use an x-jet the mixture will get diluted. If you use common 5-6% bleach/chlorine it will usulaly be too diliuted to do the job efficently and effectivley unless you apply it wiith a pump up sprayer.

I have never had a problem with vinyl siding but I would be careful with windows as they are softer plastic. Most people purchase it form a pool supplier, although Iget mine form my chem supplier.

Glad somebody on here knows enough about concrete. It seems I have been making it overly difficult by using oxalic. Bleaching out those kind of stains would be muh easier than applying oxalic to the entire area with a pump up.

Dave that is exactly why Oregon had it. The CCB was created to provide those provisions any time an improvement in the value of a home/business was performed. That was the reasoning pressure washing fell into the CCB category. I did stop some from buying $400.00 PW'er and getting to work, however non-enforcement and threats of fines did not stop the true lowballer that is willing to take his chances.

Yes it varies per state. Oregon had a CCB# (contractors certification board) requirement until mid July and dropped it. It is a system designed to collect information on contractors and make it available to the homeowners.

Concrete stains are typicaly removed with an acid. Try oxalic first and go from there.

I have actually found 3 different companies around here this year that have their name on the side of truck/trailer and when I searched there name in the state database, I find that they let their name expire years ago. This means they have no insurance and an invalid contractors license #. The part that really gets me is the companies that hire them to do the work don't even check them out.

Not over here. For once the West side is being represented and I am ready for it.

You had me hooked until that part.

Does anybody know the ratio to dilute 99.9% NaOH beads to make 50% caustic soda liquid? I have tried to find it online but only came up with a formula to dilute a liquid percentage as high as 80% to whatever percent a person wanted but nothing for diluting straight granules.

I would tell them you will do it 3x but after monitoring it may not need it more than 2x/year. This gives them the option and makes you seem even more trustworthy. One thing I don't want to do is make my services eat up more budget than they would like or expect. I have got accounts that the previous PW'er oversold the maintenance and they found it was costing too much money.

The pin lock poles can be found at paint stores. The only way I Know of to slow the draw rate of the X-Jet is with the proportioners, I think most just learn to spray faster and cover more area instead of over applying chems to one spot.

I use Ad-Aware from Lavasoft.com It is pretty well rated and finds those "data miner" cookies. It also finds registry keys as well. Best of all it is free unless you want the all inclusive version.

Most people with a Shurflo setup have it mounted on a cart with wheels. No pumping. The other option is backpack style sprayer but that is not recommended with any thing that can eat your skin, or cause sterilization.

It is a strong dangerous powder/beads. There is a lot more to making a soap than just NaOH. It will also cause discoloration on concrete and other surfaces if applied too strong or incorrectly.In nutshell yes you can use it as degreaser but always use PPE and care when trying anything.

Nope not part of a co-op, I just use it to make the fuel cost a little more bareable. Diesel fuel has jumped back up over $2.70 again and I use about 50 gallons/ week.

It can be used to make soap, strippers for wood and the kitchen guys use it for cleaning the hoods and ducts as it can be used for degreasing. I also use it to make bio-diesel.
