| P21S wheel cleaners are just as safe as DP Gel, however, they are stronger. For someone who washes their own cars regularly, DP Gel is fine, no need for something stronger AND more expensive. However, for someone with a detailing business, Id recommend P21S Gel over DP Gel. But there are always those rare occasions where you might get someone who keeps up their car, and the DP Gel will be strong enough.
It all comes down to what you're doing. |
