It works even better on extremely filthy roofs with just a little TSP added.
The Ammonyx LO reallly cuts down on the amount of TSP needed.
1/4 to 1/2 Cup of TSP per gallon maximum is plenty enough when using Ammonyx LO.
We clean a considerable number of filthy bare concrete tile roofs.
I still like some added TSP for them.
On a shingle roof, IF your customer can wait for a good rain, an "excess" amount of Ammonyx LO will dry to a film/haze.
But once a good rain comes, it re activates, and makes a stunning looking roof.
We found this out the hard way, using Ammonyx LO for the first week.
We had a really steep roof to clean, with tons of plants/shrubs all around the house, and no guttters.
Our men put an excess amount in the mix, to thicken it up.
It stuck well, and cleaned good.
It left a haze/film on the roof that was darn near impossible to rinse.
They ran out of daylight, and left.
it rained hard that night.
We came back early the next day, and were confronted with an absolutely showpiece roof!
I was telling Larry the other day, that the Condo Complex we are currently cleaning had customers actually complaining that "enough suds were not coming off of their roofs"
The first Condos we did were truly filthy, and we used a little more Ammonyx LO for them.
The second group of Condos were not a dirty, thus we used less Ammonyx LO for them
The second group customers complained that they were "short changed" because not as much Suds/Dirt were coming off their roofs :nono:
So, to make them happy, we filled one of our tanks with a water and Ammonyx LO ONLY mix, and re sprayed them
Got to make your customers happy I guess ?
