what do you guys apply the tfr with prior to washing off?   do you use a garden type pump sprayer to spray it on then was off?      or do you use a chemical inlet pipe on your pressure washer?    not used that yet?

I use a 1.5ltr prochem pump up sprayer,  and use about 3 ltrs for a small roof. You can adjust the spray to get the ornate things on top and a mist for the glass, leave it on for 10 mins and it cleans lovely. I used swafega non caustic TFR today and was more than pleased with the results

yeah i used tfr and it made thejob so easy, before i had to just use rotary washer brushes which took ages.  do you just wash it off or do you still need to scrub the algae off?

[BDCS]

I just clean it off with the WFP but a little effort given enough dwell time

[drive surgeon]

does it remove all the green off the panels by itself the tfr?

[BDCS]

No there has to  some aggitation but you could use one of those car cleaning brushes fed with the customers hose from a pair of steps
