Roof Cleaning Mix Ratios

This video is made to give the beginner a lesson on how to make a softwash roof cleaning mix.

Roof cleaning mix ratios. Again depending on climate the ratio may vary. We believe the starting ratio is 8oz for every gallon. Typically this is ajax and i ll dump 2 big containers per 50 gallons. We only use oxalic when there is rust that needs cleaning.

Same mix now added 2oz of leslie s fresh n clear now it started working with in minutes after applied to pavers and their is no he. So today i did a test old mix first i waited and waited 15 20min no result applied to pavers. Roof cleaning requires a little more skill set than house washing because the application is so hot it us much easier to kill plants and things of that nature. If it s running too much just add more soap.

Personally i go very strong and always apply 50 50. 2 2 gallons of normal 6 bleach mixed with 0 8 gallons of water will give you 42 000 ppm. As always our chemical dilutions start out at 1 ounce per gallon of mixture and you can adjust up to 4 ounces per gallon of mixture for the strongest cleaning ratio. Mix a solution of oxygen bleach and water into a pump style garden sprayer.

That s with the realization that 6 00 sodium hypochlorite is used and this is equivalent to 5 80 available chlorine. Follow the directions of the label of the oxygen bleach for proper mixing instructions. Another way to clean shingles with bleach is to combine 1 gallon of water with 1 quart bleach and 1 4 cup trisodium phosphate according to today s homeowner. The bleach to water ratio will depend on the concentration of oxygen bleach you are using.

You can adjust the amount of green wash bleach and water for your optimal cleaning solution. As for the soap i ll get any concentrated dish soap. On a standard shingle roof here i can do a 2000 sq ft house with 50 gallons of mix easy. Available chlorine is the amount of chlorine available for sterilization or moss killing in this case.

It also lets them see several examples of good and bad mix resu. Apply the oxalic scrub and the rust comes right up. As far as coverage per gallon that all depends on the roof.
