Yes, I've been reading all different posts. Suggestions appreciated. Dan

Thats what I use. 1/2 and 1/2 and a big bottle of dawn.

it is...unless your doing alot of roofs that day. You may have a 200 gal tank, but do you need 200 gal of mix?

Just because its 200 gal., you can stil mix only 50 or 100 gal in your 200 gal tank. My last roof was 35 gal sh.

u could clean the white house with 200 gallons! [lol] I have one of those huge totes [i think its like 300 gallons] and i only fill it based on the day's work. remember to try not to mix it until ur ready to use it, as when mixed the sh will begin to break down. this will be the case especially if u are using dishsoap and not ammonyx. im still using about 15 sh to 25 water. just multiply that until u get whatever amount u think u need. easy enough. good luck

It is a good idea to have a large tank for when you have a lot of roofs scheduled or a very large roof to clean that day.

I would not make up more mix than what you will use that day or in a few days because time, air, sunlight, soap, and water will start degrading the SH. Here after about a week the mix that is leftover will barely clean anything so I try to make up what I will use and if I have to make up a little bit more then that is ok because here I pay $2.58 on up per gallon. I wish it was like the Florida prices, around $1.00 to about $1.25 per gallon but it is a different part of the country and we don't have but a few places to get chemicals where in Florida you have a supplier within about a 10 minute drive in a lot of directions.

I like to keep the bulk SH separate from the mix so I have a bulk tank and a mix tank on the trailer (making up what I will use) so the bulk SH will stay strong as long as possible.

I have done most roofs with a 50/50 mix until I tried the Hang Tite from Lori at Pressure Washer Products, that stuff made the mix work better, dwell longer before running down and the overall effect was cleaning with less chemical which means more profit per job.

Thanks Lori.

A 50/50 mix is a big no no for a shingle roof, here in Florida. But our stuff is hot. We often need only 25 percent.  We dont even use that strong a mix for Tile Roofs. You want the weakest mix that will still clean, all things being equal.  It is no "sin" to have to go back and touch up a few spots that did not take, while you are still there. Contrary to what you think, overly strong chemical mixtures DO damage roofs! I have seen what strong chemical mixtures do to a roof in my early roof cleaning days, before I knew any better.  Our roof cleaning trucks have 2 tanks, one for tile roofs, one for shingle. In the beginning, I had only one tank, and 3 roofs to do one day, 2 tile, and one shingle. I was forced to do the shingle roof first !!!! I came back 3 years later, and SAW what it did ! Sure, strong chemical solutions clean faster, often in only one pass, with no touch ups.  But the roof cleaning chemical that cleans fastest, also kills plants fastest, and can even change the color of the Paint as it drips!

what happens when you use 60/40 and it doesn't clean well, does that mean the SH is weak?

are you saying never use 50/50?

what kind of damages can occur immediately and even three years later?

 

I have been using 1 quart of the Ammonyx Lo per 50 gallons of roof mix for regular roofs but for the very steep roofs I add another 1/2 quart per 50 gallon mix.

I really like this Ammonyx Lo a lot better than using dawn or other surfactants because it seems to make the chemical cling better and it does not seem to weaken the mix so it cleans better and faster.
