Having been an advocate for Meguiar’s soft top cleaner, which I do still rate as a ‘off the shelf’ solution (much better than Autoglym) I’ve come across an even more effective and low cost option.
Stage 1, brush the hood and hoover any loose debris out (same as any other process)
Stage 2, soak the top (in sections) in a solution of water and Milton sterilising tablets, leave for 5 mins and then agitate with a brush and rinse thoroughly with clean water (sufficiently firm to work out stains/mould without damaging the material - a soft/medium toothbrush works well) - this will kill mould spores and remove mould stains. Work your way around the whole hood and put it down slightly to enable access to parts of the hood hidden when the roof is fully up!
Stage 3, wash the hood with Johnson’s Baby bath (the blue bottle) - this is very gentle but works brilliantly on soft top hoods after the Milton Steriliser stage, again rinse thoroughly and allow to dry.
(You may need to repeat stage 2 & 3 depending on how bad the hood is to start with)
