Koch Chemie Green Star APC

If you're looking for a strong great value APC - then you've come to the right place. Koch Chemie Green Star is suitable for a wide range of tasks including engine bay cleaning, exterior cleaning and interior cleaning - as well as general tasks around the home or business. You must dilute this product down depending on the use you need to get the best results and the best cost benefits - so make sure to add some spray bottles on to your order. Pure Green Star is an alkaline solution of pH 12.5 - so this is not designed as a simple spray on product but instead an awesome dilutable product with a wide range of uses.

Exterior Surfaces. Dilute Green Star from 1:5 - 1:30. Use this dilution in a spray bottle or pump sprayer to clean wheels (avoid raw metal finish), under guards, engine bay, under body or exterior cleaning of heavy dirt areas. Diluted correctly this is safe for paintwork, glass etc... but make sure to not let it dry up on the surface. Dwell time should be 1-2 minutes.

Interior Fabrics. Dilute Green Star from 1:10 - 1:20. Use this dilution in a spray bottle or pump sprayer to clean interior fabrics & remove stains. Generally not recommended for leather cleaning (pH neutral is best for leather). Do not allow to dry up. Can be used in a shampoo machine.

Interior Plastics. Dilute Green Star from 1:20 - 1:40. Use this dilution in a spray bottle or pump sprayer to deep clean plastics and hard surfaces. Do NOT allow to dry. Not recommended for maintenance; but more heavy one-time cleaning of interior plastics. Dwell time should be 20-30 seconds.

Garage/Workshop Floors. Also great for this use! Dilute 1:40-1:120 with a mop or floor cleaner and rinse clean after use.

Snow Foam. Add 10-30ml of Green Star into an existing pH neutral snow foam pre-mix to enhance cleaning power.

For any purpose above always use on a cool surface and do not allow to dry. Do not use pure.

QTY: 1x1000ml Bottle or 11,000ml Tub

ALWAYS dilute as per the uses specified in the product description. Do not allow the product to dry - and ensure to rinse or remove thoroughly. If you have any questions contact United Car Care.

At first I was skeptical

I originally thought APC like this was just rebottled cleaner, stuff that could be equalled by Simple Green or dishwashing liquid in a bottle. Oh boy was I wrong! Cuts through anything with ease (1:10 dilution), pleasant smell, doesn't need a lot of pressure or liquid. Will get the bulk load straight away when available.

APC for anything

Splurged out and got the 11 litre bulk amount. Finding I'm using it for everything Varying the dilution makes it very versatile Even putting a splash into my MIT shampoo for more lift

My go to APC

Have used this for everything from interior plastics deep cleaning, engine bay perp for dressing, to brush and pad cleaning. Time to go 4ltr quantity, as I'm using all the time.

Very good on the Bike.

Like others I've been using this diluted 1:10 ratio in a 1L spray bottle (also a useful product) as a pre-wash dirt remover on wheels and the underside of the bike. It won't make the grime "fall off" But the grime comes away really easily with a brush or cloth. Especially as I don't want to use high pressure water around wheel bearings etc on the bike. I'd avoid leaving it too long on a surface and don't let it dry to be safe.

A very strong and efficient solution for an APC. Used 1:20 and it still powers through heavy grime, windscreen gunk, insects and generally anything that needs a scrub. It won't magically make nasty stuff disappear, but it helps a lot. Very, very efficient and the 1L bottle can last you quite a while if diluted correctly to you application. Tends to still foam up quite well when agitated with a brush at 1:20. Has a slight stale pond water kind of smell when sprayed in the air or evaporating, but nothing nauseating or irritating for me. Highly recommended for anyone on a budget.
