USE THE TWO BUCKET METHOD
I highly recommend the use of two buckets when washing your car. One of the buckets is going to be a clean water rinse for your wash mitt and the other bucket will contain your soapy car wash solution. When you see how dirty the water in your clean water rinse bucket gets, you will thank me for telling you about using two buckets when washing your car.
Fill your first bucket with about 2 gallons of water, add the appropriate dilution of car wash soap and then agitiate with a strong jet of water to create copious amounts of suds. These suds with help lift dirt and grime away from your paint.
Fill your second bucket with about 3 gallons of clean water. You will use this bucket to dunk your wash mitt in after using it to clean your vehicle.
The proper steps to using the two bucket method are as follows:
1. Prepare two five gallon buckets, one with clean water and the other with soapy car wash solution.
2. Rinse vehicle thoroughly. This will remove loose dirt and contaminants.
3. Dunk your wash mitt into the soapy car wash solution, gently glide mitt over vehicle to lift dirt from surface. Start at the top of vehicle and work your way down. This is important to prevent transferring dirt from the grimier lower areas up to the rest of the vehicle. Use long straight sweeping motions with the wash mitt. Do not scrub. Allow the soap and water mixture to do the work.
4. Dunk wash mitt vigorously into clean water rinse bucket to clean mitt and remove any dirt and contaminants that were removed from the vehicle surface.
5. Dunk wash mitt into soapy car wash solution again, gently glide over vehicle to lift dirt from surface.
Repeat this process until you have washed the entire vehicle and then rinse thoroughly.
