easy there, didn't mean to touch a nerve lol!!
Nobody said a babywipe will be a match for purpose products that are designed for maximum effect and give long lasting results.
But then as the original poster was going to go at it with a brush and some washing up liquid, may he wants a quick easy way to remove some of the grime, and in the past I have found baby wipes an effective non agressive way to remove grime from trim with ease.
The op asked for suggestions, and i gave one, he may opt for the specialised product route, he may not, now he has an option.
