How much straight Sodium Percarbonate should I mix with water for a standard size load of laundry?

Question:I would also like to know the ratios that should be mixed for cleaning cedar wood siding..

Answers:
For light soils add 1ounce of Sodium Percarbonate with your laundry detergent per load. For moderate soils use 2 ounces and for heavily soiled articles use 4 ounces. To whiten and deodorize diapers or to destain cloth menstrual pads add 4-6 ounces of Sodium Percarbonate
In the laundry Sodium Percarbonate is used to destain, deodorize, and whiten.

To remove weathered stains from wood decking, fencing, siding, concrete, and stucco, use a general cleaning solution and apply with a clean lawn sprayer. Let stand 10-30 minutes, scrub if necessary and rinse thoroughly. Or mix a general cleaning solution in a bucket and apply with a broom or brush, then scrub and rinse thoroughly.

General Cleaning: Mix 4 oz of percarbonate in a gallon of warm or hot water. (1 oz per quart).
Heavy Cleaning: Mix 8 oz of Percarbonate in a gallon of warm or hot water. (2 oz per quart)
