it looks like formula 90 cost 100 bucks!
Like i said before, check with your “local” carpet cleaning supply 1st. you must be looking at a 50lb container? that would last you a loooong time and whole lotta screens! Look for a 6 lb jar, much cheaper.
Is tide with bleach alternative just as effective.
It works I believe better. IMHO, otherwise I never would have recommended it. By the way, if you all havent figured it out yet… try mixing it with Hot water from a tap. WOW!! Lance’s disclaimer, : if you get it from customers bathtub and carry the bucket through the house and spill water, you are on your own!;)Again, if you check with your local carpet or janitorial supply, look for a “bucket heater” about $50, start your job with filling water into bucket and plug in bucket heater, give it about 20 minutes and hot water.
stay away from pressure washing of screens, IMO it is hard on the material.
Besides the fact you can leave “streak” marks in them.
I use a soft nylon “truck brush” that you can find at almost any local janitorial supply. it has a screw on end to match most poles.
If any of you have any questions regarding any of this, please dont hesitate to call me anytime.
