There is a lot of information out there on mixing, and some may find that other methods work best. We have compiled some information that beginners and new washers might find useful! Please test everything yourself before trying. We are not responsible for any damage resulting from these instructions.
Take Into Consideration
House wash mix can vary depending on the ratio your downstream injector pulls, and the temperature (climate) you are washing.
A typical house wash can be done using 1 or 2, 5 gallon, buckets of mix. Start with a mix ratio of 1:1. This means for every gallon of bleach you use, add 1 gallon of water. As an example, in a 5 gallon bucket, mix 2 gallons of bleach, with 2 gallons of water, and typically 4-5oz of surfactant (depending on the surfactant you use).

Red Raider found at southside equipment (sales rep is Russ Johnson on facebook) is an amazing degreaser that can safely be used with house washing. We have started adding this to our house wash mix and we are very happy with results. We typically cut the surfactant use in half and replace it with Red Raider.
Example: 4 gallons of House wash mix will get 2 oz of ELEMONATOR (or your surfactant of choice) and then 2 oz of Red Raider. Surfactant measurements are more of a personal preference thing. Some guys like a lot of suds. Personally, too much can be overkill and cause you to spend way too much time rinsing. You have to find your happy place.
DO NOT use Dawn dish soap as a surfactant. It is not bleach stable, and can produce hazardous gas/fumes to your health.
Not Strong Enough?
If you are finding the mix is not strong enough step it up to 2:1. If that is not strong enough, go forward with straight bleach in a 5 gallon bucket with added surfactant. House washing is pretty fool proof. By the time the mixture comes out the end of your hose, the ratio is pretty low and it is rather safe to work with.
Cleaning & Upkeep
ALWAYS make sure to flush your down stream injector with a MINIMUM of 2 gallons of water after each job to ensure long lasting life of injector. We always shoot for 5 gallons.
