What can I use to clean it? Will it be ok to HWE? Also, what pre-spray would you recommend?

Not something I usually do but a client has asked me to take a look.

Thanks

Ive valeted soft tops with pressure washer (not too close mind) hwe or just by hand with a soft brush to aggitate. should probably seal it after a deep clean also. modern soft tops are hardwearing.

If it has gone really green it can be hard to clean even with a pressure washer. You will need to scrub with a soft scrubbbing brush or nail brush. you can use HWE but probably you will get better results with a pressure washer. Halfords or other car accessory shops sell cleaner and protector packages which are ok but protect the paintwork when using them. It is easy enough to make an improvement, to get it really good can be hard.

Done loads of these!
 Once i have gently pressure washed the roof to remove surface debris, I use Autosmart's G101 and a nail brush.
Leave to dwell for 5-10 mins and rinse off.
NEVER get the end of the lance nozzle too close as this can damage the fabric!!!

Dry the fabric and then use a solvent based protector

Leaving G101 on a canvas roof for 10 minutes is dodgy as its a very aggressive cleaner and could cause damage or fading, the idea is right but just to use a safer cleaning solution,

Thanks for the reply's!

Would a extraction machine on high psi be enough? I don't have access to a pressure washer.

I can turn up the psi to 800.

I would recommend to pre spray the roof with a non-caustic,non-corrosive, based cleaner then scrub the surface with a soft to medium bristle brush and just use a microfiber cloth and bucket of water to rinse down.

I have used alsorts G101, TFR dont let it dry and if using power washer don't get to close.
I do 4 soft tops on a reg basis never had a problem mingers may take a few goes.

The only way it could pose a possible threat is if it was left to dwell in direct sunlight , dwell time will vary depending on the level and type of soil.
G101 is not caustic and safer to use than TFR...

Hi Russ, I am only sharing my experience of using such products in the past and will never again use high alkaline based products on any of our clients surfaces, for safety when using cleaning chemicals if the ph value is over 10 its better not to use them as these high alkaline based chemicals will cause damage to surfaces. i will put my hand up and admit that in the past i have damaged clients surfaces from using high alkaline based chemicals as when i came into the industry many years ago no warned us of the detrimental damage these chemicals can cause, so i hope this information can be of benefit to the new guys coming into our industry.

I've done loads of these. I brush to loosen dirt, good vac, then pre-spray Mpower boosted with an oxygenator. If there's a lot of sap, I might add about 100ml of eco-pog to that mix. Good long dwell and brushing - extract. Then seal. takes an hour - happy customer
