chemical - NaOH

Does anyone use raw NaOH in the micropearls form (granular) instead of beads? Does it work as well?
 
We use a premixed solution...

We use neither. We use a premixed solution (25%) that has an additive that makes it slightly thicker to stick to the duct work a little bit. Then we dilute it before we use it.
 
We use a liquid kit, five gallons make 55 gallons. It can also be bought in bulk and your mixed priced can be well under $1.00 per gallon!!!!!
 
What is NaOH, what is the raw form? Potasium Hydroxide or Sodium Hydroxide?

NaOH = Sodium Hydroxide
KOH= Potassium Hydroxide

Caustics are strong alkaline chemicals, corrosive to many materials including human tissue. Sodium hydroxide (NaOH) and potassium hydroxide (KOH) are the two most important caustics used in industry, with over 10 million tons of NaOH alone produced annually in its various forms.

Rusty what is your additive to make it stick, or is that a closley guarded secret.
 
That’s an ancient Chinese secret. Oops, spilled one of the secrets to cleaning Chinese restaurants.

I'll have to ask our chemist what the technical name is, but it makes it just a little bit thicker than usual so that when it sprays on the duct work it stays just a little longer and kind of slides down.

We prefer to use the premixed (consistency and safety) even though it is a little bit more expensive.

Each 15 gallons (60 quarts) on average will clean about 40-60 restaurants which on average is about $8000 - $12,000 profit per container. So cost vs efficacy vs profit equals a premixed solution. We dilute 1 quart into a 2 gallon container and use that amount for the job.

We adjust the concentration by increasing or decreasing the amount of diluents that we add.

Disadvantage of the premixed is that the freezing point is around 50' F. So you have to take precautions to keep the temp inside of your trailer above that temp. We use portable ceramic disc heater with a thermostat to heat the inside of our well insulated trailers to keep it nice and toasty during the winter months.

Cost per 15 gallons + shipping is around $120. Which cost about $2.00 per quart. So your cost per job is around $2.00-$6.00 per job for chemicals.

Aw, Bryan, now you have "done made me" type too many words.
