I'm gonna stop using sponge to wash car. Just found that sponge are easy and faster to wash, due to habit frommany years. But recently read an article from a detailing website, stated that sponge are the worst for car washing coz it hides dirt that damage car paint. And it cannot properly wash a car surface. Any suggesting for me? Using cloth better right?
Not all 'sponges' are detrimental to the paintwork. Good quality 'Sponges' that are specifically made for washing cars are as good as lambswool/sheepskin or microfibre wash mitt. Ultimitt, Shmitt, LC 'sponge' (all are now locally available) are a few samples of good quality 'sponges' that's quite safe to use.
The 2 buckets method means one bucket soap water one bucket clean water. Every time must wash the washing material with clean water before dripping it into the soap water again right?
Can I not use grid-guard by not dripping to deep under the bucket to avoid the dirt?
With a good quality wash mitt, the Two Bucket Method (TBM) would further *minimise* the chance of inflicting wash induced swirls.
To simply put it, pick up the soapy water from the shampoo bucket, wash the car a section at a time, wring the sponge/mitt, dip it in the other bucket containing water to rinse off the dirt that's been *captured* by the sponge/mitt and dip it back into the soapy water to wash again.
This way, whatever dirt that the sponge/mitt picked up during the wash cycle are released/rinse out so that it's not in the sponge/mitt to cause any swirl/scratches.
The grit guard main function is to *trap* the dirt at the bottom of the pail/bucket hence preventing them from being picked up by the sponge/mitt when rinsing. You don't really *need* the grit guard if you're really careful when rinsing the sponge/mitt but it's a good tool to have.
