After reading the
http://www.detailingworld.co.uk forum, I though about trying one of these.
This is a B&Q tile (or grout) sponge, softer then the traditional sponges and have lots of holes in to trap dirt. Sponges are a bit of a grey area, as their firm surface can trap and drag grit along the paint causing marring, but can produce a thick load of suds on the paintwork, more so then using a washmitt.
At £1.48, these are cheaper then a ultra-soft Zymol sponge (£5) or lambswool or microfibre washmitt (about £8). In fact, my local Sainsbury's wanted more than £1.48 for a normal sponge!
Hopefully, I can give it a try tomorrow, probably using the Zymol sponge on the top half then this one on the bottom half, relegating my Meguiar's microfibre washmitt to wheel cleaning duty.
